QSFP-100G-SR1.2 Overview
QSFP-100G-SR1.2 is a Cisco QSFP28 SR-BiDi optical transceiver for 100 Gigabit Ethernet short-reach links. It uses multimode fiber, duplex LC connectivity, and 855 nm plus 908 nm bidirectional wavelengths. The module supports 70 m over OM3, 100 m over OM4, and 150 m over OM5. Its two optical lanes carry 50 Gb PAM4 channels across a two-strand MMF plant. Cisco positions the optic for data center, enterprise core, distribution, and service provider access designs. This hot-swappable form factor plugs into Cisco 100G QSFP ports without replacing LC fiber trunks. Commercial temperature class operation suits controlled rack environments and planned refresh windows. Digital diagnostic monitoring works through the QSFP management interface for optical and module telemetry. Its LC interface keeps patching familiar for existing multimode distribution frames. QSFP-100G-SR1.2 helps teams reuse 10G, 40G, and 100G duplex MMF cabling during speed upgrades.
VCSEL transmitter lanes deliver short-wave bidirectional signaling across 855 nm and 908 nm windows. PIN receiver lanes deliver optical recovery from the paired MMF channel with 4 dBm overload tolerance. QSFP-100G-SR1.2 specifies -6 dBm to +4 dBm transmit power per lane at 100G. Receiver input requires -7.9 dBm minimum power per lane for the published optical budget. The electrical host interface follows IEEE 802.3bm 100GBASE-SR4 behavior through four 25G electrical lanes. PAM4 encoding maps two 50 Gb optical lanes into the aggregate 100GbE link. KP4 FEC reduces transmission errors at the 100Gbps data rate. The optical budget supports 1.9 dB link loss for OM3, OM4, and OM5 at 100G. Average optical power values guide acceptance testing. SFF-8665 defines the QSFP28 mechanical solution, while SFF-8636 defines common management access. The module draws 3.9 W maximum from a 3.3 V QSFP supply during operation. Cisco lists IEEE 802.3-2022, IEEE 802.3ba, IEEE 802.3bm, GR-20-CORE, GR-468-CORE, and RoHS 6 alignment.
QSFP-100G-SR1.2 fits Cisco QSFP-100G portfolios across validated switches and routers listed in Cisco compatibility tools. Network teams deploy it in leaf-spine fabrics, top-of-rack uplinks, aggregation layers, and 400G SR4.2 breakout designs. OM4 cabling supports the common 100 m target, while OM3 and OM5 cover shorter or extended SR-BiDi runs. ORM Systems offers this Cisco transceiver in new and refurbished condition for upgrade, sparing, and lifecycle programs. Each supplied unit receives compatibility screening, optical inspection, and serialized handling before dispatch. Procurement teams gain tested inventory, responsive sourcing support, and straightforward replacement planning. Project buyers receive practical condition choices, quote traceability, and support for standardized sparing lists. Engineering teams keep fiber maps stable while moving access and aggregation ports toward higher speed. Buy QSFP-100G-SR1.2 from ORM Systems when you need LC duplex 100GbE without new MPO trunks.

QSFP-100G-SR1.2 Use Case
Leaf-Spine Fabric Uplinks
Network architects place QSFP-100G-SR1.2 between leaf and spine switches where 100GbE bandwidth rides existing duplex LC multimode trunks. The SR-BiDi design avoids MPO conversion work, preserves OM4 patching, and keeps rack projects focused on port upgrades. PAM4 lanes and KP4 FEC maintain signal quality across the short-reach fiber budget. Operations teams standardize spare optics across validated Cisco QSFP ports, reduce cabling disruption, and deliver predictable east-west throughput for virtualized, AI, and storage traffic across the data center fabric with consistent operational telemetry.
Top-of-Rack Server Aggregation
Infrastructure teams deploy QSFP-100G-SR1.2 on top-of-rack uplinks that aggregate dense server traffic over duplex LC MMF. The optic supports 100 m over OM4, matching many row and pod layouts without changing patch panels. Cisco QSFP28 compatibility, DOM telemetry, and tested ORM Systems supply support controlled turn-up and spare pool management. The design strengthens rack-level bandwidth, keeps migration windows shorter, and delivers stable north-south paths for compute, storage, and virtualization clusters. Teams preserve cable maps, simplify rollback plans, and deliver tested 100G uplink capacity per rack.
400G Breakout Migration
Network planners use QSFP-100G-SR1.2 as the 100G endpoint in validated 400G SR4.2 breakout projects. A spine or top-of-rack 400G port fans out to four 100G SR-BiDi links, while LC multimode cabling remains in service. The approach phases bandwidth growth by rack, link group, or site. Procurement teams source matched optics through ORM Systems, align spares with Cisco platforms, and deliver measured 400G migration outcomes without broad fiber replacement. Operations teams preserve LC workflows, reduce patching risk, and document repeatable upgrade results.
