SFP-10G-ZR-S uses the SFP+ form factor for hot-swappable placement in Cisco Ethernet SFP+ ports and optical uplink slots. Line operation provides 10 Gbps Ethernet signaling through Cisco 10GBASE-ZR S-Class interfaces for long-reach optical transport. Optical media is single-mode fiber with G.652 characteristics for extended-distance links across metropolitan and service provider spans. Duplex LC/PC connectors provide separate transmit and receive paths through PC or UPC patch cords in the optical interface. Wavelength operation uses 1550 nm optics across the 1530 nm to 1565 nm transmit window for long-reach signaling. Maximum reach is 80 km on OS1/OS2 across engineered G.652 single-mode links. SFP-10G-ZR-S carries the Commercial operating temperature class for standard Cisco S-Class module environments. Digital optical monitoring reports output power, input power, temperature, laser bias current, and transceiver voltage through DOM capability.
An EML transmitter launches stabilized 1550 nm optical output for Cisco S-Class long-reach Ethernet operation across SFP+ host ports. APD receiver architecture converts low-level single-mode optical input into electrical signaling for the host interface and diagnostic path. TX power delivers 0 dBm to 4.0 dBm average launch power across Cisco ZR optical operating conditions. RX sensitivity reaches -24 dBm at the receive minimum input level for 10GE LAN and WAN operation. Receiver overload tolerates -7 dBm at the maximum receive input level before optical front-end saturation occurs. With 64b/66b encoding, 10GBASE-R framing carries Ethernet payloads across the serial optical lane and host interface. SFF-8431 and SFF-8472 establish SFP+ electrical interface behavior and digital diagnostics for compatible host ports. At 3.3V, the host electrical interface supplies the module through the standard SFP+ low-voltage rail. Power consumption stays at 1.5 W for SFP-10G-ZR-S during Cisco 10GBASE-ZR optical operation across supported host installations.
Cisco 7600, ASR 1000, ASR 9000, Catalyst 4500-X, CRS, NCS 6000, and Nexus 9000 platforms match deployment. Deployment environments span metro Ethernet, service provider transport, data center interconnect, enterprise aggregation, and long-distance campus uplinks. Required cable grade is OS2 for 80 km installations over G.652 single-mode plant. Shorter links require inline attenuation to protect the receiver from high optical input power. Engineered ZR spans fit routed WAN edges, aggregation rings, and extended fiber paths needing long-reach Ethernet optics.

The Cisco SFP-10G-ZR-S operates as a long-reach 10 GbE uplink between sites connected by standard G.652 single-mode fiber. Its S-Class 10GBASE-ZR design supports links up to about 80 km and uses 1550 nm optics, keeping the link focused on Ethernet transport rather than FCoE. In this role, SFP-10G-ZR-S carries routed or switched uplink traffic across a metro fiber span. The network gains a defined 10 GbE intersite path without deploying separate optical transport equipment at the site edge router.
The SFP-10G-ZR-S sits in a data center interconnect handoff where two switching domains need 10 GbE over long single-mode fiber. Its Cisco ZR specification reaches about 80 km on G.652 SMF, and the S-Class profile keeps the optic scoped to Ethernet services. This placement fits direct switch-to-switch connectivity across a carrier dark-fiber route or private campus fiber span. The interconnect gains a single-port 10G optical path with distance aligned to the outside-plant fiber design and core uplink capacity plan.
The Cisco SFP-10G-ZR-S operates as a remote aggregation uplink where a downstream switch sends 10 GbE traffic back to a core site over single-mode fiber. Its 1550 nm 10GBASE-ZR optical interface supports about 80 km on G.652 fiber, giving the aggregation node reach beyond LR and ER optics. The S-Class module keeps the connection dedicated to Ethernet forwarding. The topology gains a long-span 10G return path that reduces intermediate active handoffs between the remote aggregation point and core site.

SFP-10G-ZR-S is a Cisco 10GBASE-ZR S-Class SFP+ optical transceiver for long-distance 10 Gigabit Ethernet over single-mode fiber. It uses a 1550 nm optical interface, dual LC connectors, and digital optical monitoring. Cisco lists support for links up to about 80 km on standard G.652 single-mode fiber.
SFP-10G-ZR-S identifies a Cisco SFP+ 10 Gigabit Ethernet ZR transceiver in the S-Class portfolio. SFP+ defines the compact pluggable form factor, 10G identifies the data rate, ZR indicates extended 1550 nm long-reach operation, and the final S marks Cisco's S-Class version for Ethernet-focused enterprise deployments.
SFP-10G-ZR-S is an optical transceiver module, not a fixed cable. It plugs into a compatible Cisco SFP+ port and connects to separate single-mode fiber patch leads. The module uses duplex LC connectors, so buyers should use LC/PC or LC/UPC single-mode fiber patch cords and avoid APC patch cords.
SFP-10G-ZR-S sits in Cisco's 10GBASE SFP+ family as the S-Class long-distance 1550 nm ZR option. It is positioned above LR and ER optics for longer single-mode fiber paths. Related Cisco 10G options include SFP-10G-LR-S, SFP-10G-ER-S, SFP-10G-ZR, SFP-10G-ZR-I, SFP-10G-LRM, and SFP-10G-SR-S.
SFP-10G-ZR-S uses the SFP+ form factor for 10 Gigabit Ethernet ports. Cisco SFP+ modules are hot-swappable, allowing replacement in compatible SFP+ slots without powering down the host platform. The compact form factor supports high port density on Cisco switches, routers, and fabric platforms compared with older XENPAK, X2, or XFP optics.
SFP-10G-ZR-S supports 10 Gigabit Ethernet operation through a 10GBASE-ZR optical interface. Cisco states that ZR is not part of the IEEE 10 Gigabit Ethernet standard and is built to Cisco specifications. The S-Class module does not support FCoE, so buyers needing broader protocol support should evaluate non-S-Class ZR variants.
SFP-10G-ZR-S uses a 1550 nm long-reach optical interface, with Cisco listing the optical wavelength range as 1530 to 1565 nm. This wavelength is used for long single-mode fiber spans. It should be paired with another compatible 10GBASE-ZR optical interface, using standard G.652 single-mode fiber and the required optical power budget.
SFP-10G-ZR-S supports link lengths up to about 80 km on standard G.652 single-mode fiber. Cisco notes that shorter links under 40 km require an inline optical attenuator to avoid receiver overload and possible damage. Final reach depends on fiber loss, splice quality, connector cleanliness, chromatic dispersion, patching, and link engineering.
SFP-10G-ZR-S uses a dual LC/PC connector for transmit and receive fiber strands. Cisco supports patch cords with PC or UPC connectors and does not support APC patch cords for these SFP+ modules. Buyers should use duplex LC single-mode fiber patch leads and verify polarity, loss, and connector cleanliness before installation.
SFP-10G-ZR-S supports digital optical monitoring as part of Cisco's SFP+ module family, giving compatible host platforms visibility into temperature, supply voltage, laser bias current, optical transmit power, and optical receive power. DOM is especially useful on 80 km ZR links because engineers can check receiver levels, attenuation, and fiber loss during commissioning.
SFP-10G-ZR-S is used for long-distance 10G Ethernet links over single-mode fiber. Typical uses include campus-to-campus connectivity, metro fiber handoffs, data center interconnects, service provider access, disaster recovery links, and enterprise aggregation paths. It fits designs where 10 km LR or 40 km ER optics do not provide enough reach.
SFP-10G-ZR-S fits enterprise, service provider, campus, and data center environments that need 10G connectivity across long single-mode fiber spans. It is especially relevant for sites separated by tens of kilometers. Buyers should confirm fiber route loss, provider handoff specifications, attenuation needs, and Cisco platform compatibility before selecting ZR instead of LR or ER.
SFP-10G-ZR-S suits Ethernet workloads that need 10 Gbps transport over long single-mode links, including data replication, campus aggregation, storage Ethernet, WAN edge interconnects, service provider Ethernet, backup traffic, and high-capacity building interconnects. It is not intended for multimode fiber, FCoE, short unmanaged patching, or 25G upgrades.
SFP-10G-ZR-S can work in metro fiber deployments when the fiber route uses standard G.652 single-mode fiber and the optical budget fits Cisco's ZR specifications. The module is useful for long dark-fiber or provider-managed spans. Engineers should validate attenuation, chromatic dispersion, splice loss, connector loss, and any required inline attenuator before service turn-up.
SFP-10G-ZR-S is supported on selected Cisco platforms with compatible SFP+ ports, subject to Cisco's transceiver compatibility matrix. Cisco lists broad families for 10G SFP+ modules including Catalyst switches, Nexus 2000, Nexus 3000, Nexus 9000, Nexus 9500, MDS 9000, CRS routers, ME platforms, shared port adapters, SCE 8000, and UCS switches.
SFP-10G-ZR-S can work with supported Cisco Nexus switches when the exact model, line card, port type, and software release appear in Cisco's compatibility matrix. Common deployment areas include Nexus 3000, Nexus 9000, and Nexus 9500 environments that need long 10G single-mode uplinks. Buyers should confirm optic support before ordering for production fabrics.
SFP-10G-ZR-S can work with supported Cisco Catalyst switches that provide 10G SFP+ ports and list the module as compatible. Cisco's SFP+ data sheet references Catalyst families such as 3560, 3560-E, 3560-X, 3750, 3750-E, 3750-X, 3850, 4500, and 4500-X. Exact support depends on uplink module, switch model, and software release.
SFP-10G-ZR-S uses Cisco-specified 10GBASE-ZR operation rather than an IEEE-defined 10G Ethernet standard. Cisco lists 1550 nm SMF G.652 cabling, 80 km reach, 0 dBm minimum transmit power, -7 dBm maximum transmit power, -24 dBm receiver sensitivity, and a 1600 ps/nm maximum chromatic dispersion value for SFP-10G-ZR and SFP-10G-ZR-S.
SFP-10G-ZR-S is the S-Class enterprise-focused ZR module, while SFP-10G-ZR is the multirate ZR module. Both support about 80 km over G.652 single-mode fiber at 1550 nm. SFP-10G-ZR supports 10GBASE-ZR, 10GBASE-ZW, and OTU2/OTU2e, while SFP-10G-ZR-S is intended for Ethernet-focused deployments and does not support FCoE.
SFP-10G-ZR-S is a commercial-temperature S-Class optic with about 80 km reach, while SFP-10G-ZR-I is the industrial-temperature migration option listed by Cisco. SFP-10G-ZR-I supports about 70 km over G.652 single-mode fiber and operates across an industrial range, with optical traffic limitations during very low-temperature cold start. Cisco lists SFP-10G-ZR-I as the migration SKU.
SFP-10G-ZR-S is a 1550 nm ZR optic for up to about 80 km over single-mode fiber. SFP-10G-ER-S is a 1550 nm ER optic for up to 40 km over single-mode fiber. Buyers choose SFP-10G-ZR-S when fiber distance or optical budget exceeds ER reach, and SFP-10G-ER-S when 40 km is sufficient.
SFP-10G-ZR-S supports about 80 km over G.652 single-mode fiber at 1550 nm, while SFP-10G-LR-S supports 10 km over single-mode fiber at 1310 nm. SFP-10G-LR-S is normally used for campus or building links, while SFP-10G-ZR-S is selected for long metro, inter-site, or extended dark-fiber routes.
SFP-10G-ZR-S new Cisco ordering is now limited because Cisco's end-of-sale date for the SKU was June 10, 2026. ORM Systems can check remaining channel, surplus, or special-source availability where possible. Buyers should also consider Cisco's listed migration product, SFP-10G-ZR-I, when a currently supported Cisco replacement is acceptable.
SFP-10G-ZR-S can be requested from ORM Systems in certified refurbished condition when stock is available. Cisco also notes that SFP-10G-ZR and SFP-10G-ZR-S may continue through Cisco Refresh in limited supply until the last support date. Refurbished stock should be tested for DOM reporting, link stability, optical power behavior, and connector condition before dispatch.
SFP-10G-ZR-S pricing depends on condition, quantity, Cisco original status, remaining channel stock, refurbishment availability, warranty cover, and delivery destination. ZR optics usually cost more than SR, LR, or ER modules because they support longer reach and tighter optical requirements. ORM Systems can quote single modules, matched pairs, project quantities, or migration alternatives.
SFP-10G-ZR-S has an announced Cisco end-of-sale and end-of-life schedule. Cisco announced the milestone on June 10, 2025, set the last order date as June 10, 2026, and lists the last ship date as September 9, 2026. The last date of Cisco support is June 30, 2031.
SFP-10G-ZR-S lead time depends on remaining stock, required quantity, testing queue, matched-pair needs, and shipping destination. Since Cisco's last order date has passed, availability may rely on distributor residual stock, Cisco Refresh, certified refurbished inventory, or surplus supply. ORM Systems can check stock, confirm condition, and provide realistic dispatch timing before purchase.
Bulk pricing for SFP-10G-ZR-S may be available when ORM Systems can source multiple Cisco original, Cisco Refresh, or certified refurbished modules. Volume buyers should provide quantity, deadline, acceptable condition, target platforms, and whether SFP-10G-ZR-I substitution is allowed. Bulk orders are useful for long-distance 10G spares, metro upgrades, and multi-site network maintenance.
SFP-10G-ZR-S warranty terms from ORM Systems should be confirmed in the quotation because supply may be new-surplus, Cisco Refresh, or certified refurbished. Cisco support remains available only under eligible active service contracts until the listed support end date. ORM Systems can state reseller warranty duration, replacement process, testing scope, and any compatibility exclusions before shipment.
Refurbished SFP-10G-ZR-S stock should be tested for Cisco identification, DOM visibility, clean LC connectors, stable 10G link operation, optical transmit level, receive sensitivity behavior, and host platform acceptance. Long-reach ZR optics should also be checked carefully for receiver overload risk on short test links using proper attenuation before dispatch.
SFP-10G-ZR-S is part of Cisco's 10GBASE SFP+ module family and uses Cisco-specified 10GBASE-ZR operation over G.652 single-mode fiber. Cisco SFP+ modules include digital optical monitoring and Cisco quality identification. Buyers needing formal documentation should request current laser safety, EMC, RoHS, and country-specific compliance documents for the exact supplied module.
SFP-10G-ZR-S installs by inserting the module into a compatible Cisco SFP+ port, connecting duplex LC single-mode fiber, and checking link status and DOM levels. Engineers should clean connectors, verify the far-end optic, confirm route loss, and use an inline optical attenuator for links under 40 km to prevent receiver overload.
SFP-10G-ZR-S does not require a separate optic license, but the host Cisco platform must support the module, software release, and 10G SFP+ port type. Some platforms can restrict optics by hardware generation or software version. Buyers should check Cisco's compatibility matrix before ordering, especially for Nexus, Catalyst, MDS, UCS, router, and SPA deployments.
SFP-10G-ZR-S requires duplex LC single-mode fiber patch leads and a suitable G.652 single-mode fiber path. Cisco supports PC or UPC connectors and does not support APC patch cords. Installers may also need inline optical attenuators for links under 40 km, fiber cleaning tools, inspection scopes, labels, dust caps, and optical power testing.
