SFP-10G-SR-S

SFP-10G-SR-S uses the SFP+ form factor for hot-swappable placement in Ethernet SFP+ ports on Cisco switch and router host slots. Link operation provides 10 Gbps Ethernet signaling through Cisco 10GBASE-SR S-Class host interfaces and compact optical module cages. Optical media is multimode fiber with 50-micron laser-optimized cabling for short-reach transmission across Cisco-supported campus links. Duplex LC/PC connectors provide separate transmit and receive paths through PC or UPC patch cords in the optical interface. Wavelength operation uses 850 nm optics across the 840 nm to 860 nm transmit-and-receive window for shortwave signaling. Maximum reach is 400 m on OM4/OM5, 300 m on OM3, and 82 m on OM2. SFP-10G-SR-S carries the Commercial operating temperature class. Digital optical monitoring reports optical power, supply voltage, module temperature, and laser-bias current through DOM capability.

A VCSEL transmitter launches shortwave optical output through the laser source for Cisco S-Class Ethernet-only SR module operation. PIN receiver circuitry converts incoming optical signals into electrical output for the host SFP+ interface and monitoring path. TX power delivers -7.3 dBm to -1.2 dBm average launch power across Cisco optical operating conditions and links. RX sensitivity reaches -9.9 dBm at the receive minimum input level for the short-reach optical budget. Receiver overload tolerates -1.0 dBm at the maximum receive input level before optical front-end saturation occurs. With 64b/66b encoding, serial 10GBASE-R framing carries Ethernet payloads across the optical lane and host interface. IEEE 802.3 and SFF-8431 establish Ethernet operation and SFP+ optical module interface requirements for host ports. At 3.3V, the host electrical interface supplies the module through the standard SFP+ low-voltage rail. Power consumption stays at 1 W for SFP-10G-SR-S during Cisco S-Class SR module operation across supported hosts.

Cisco 250 Series, Nexus 22XX, 30XX, 31XX, 3548, 93180, 93XX, ONE Nexus 55XX, UCS 62XX, and C4200 platforms match deployment. Deployment environments span data center, enterprise wiring closet, and service provider transport networks for Ethernet uplink projects and structured growth. Required cable grade is OM4/OM5 for highest-distance installations and OM3 for shorter supported runs. OM2 cabling serves legacy installed plant where the listed modal bandwidth remains within Cisco cabling limits. Campus aggregation, top-of-rack switching, access uplinks, and spare inventory planning fit the documented platform families.
