SFP-10/25G-LR-S Overview
SFP-10/25G-LR-S is a Cisco S-Class optical transceiver built in the SFP28 form factor for supported Cisco 25GBASE switching ports. The module operates at dual 10G and 25G Ethernet data rates on supported SFP28 host interfaces in Cisco hardware. Its optical interface uses standard single-mode fiber for LR Ethernet transmission across long physical paths. A dual LC/PC connector provides the removable fiber interface for transmit and receive strands. The optical channel uses 1310 nm wavelength for both transmit and receive directions. Maximum supported link distance is 10 km over standard G.652 single-mode fiber. The hardware uses Cisco's commercial temperature class for normal operating environments. Digital optical monitoring is present through the module's diagnostic monitoring interface support. The S-Class part number separates this optic from industrial temperature and bidirectional Cisco LR variants in the portfolio.
TX power range delivers -8.2 to +0.5 dBm at 10G and -7.0 to +2.0 dBm at 25G. RX sensitivity reaches -14.4 dBm at 10G and -13.3 dBm at 25G. RX overload point accepts +0.5 dBm at 10G and +2.0 dBm at 25G. With RS-FEC, host ports operate the 25G link according to Cisco requirements. For 10G operation, the host port does not require FEC. SFP-10/25G-LR-S follows SFF-8402 for the SFP28 pluggable module interface. IEEE 802.3by and IEEE 802.3cc govern the 25G Ethernet optical behaviour. SFF-8472 provides the diagnostic monitoring interface for optical reporting. Average power measurements use dBm units for transmitter and receiver performance thresholds. Optical transmit and receive specifications use separate 10G and 25G values for power limits. At 1.3 W maximum power consumption, the module fits Cisco SFP28 port power budgets. FCoE support operates with appropriate host software support. RoHS 6 compliance addresses material restrictions for enterprise procurement documentation.
Cisco ASR 9000, Cisco Nexus 9300-FX2, and Cisco NCS 5500 hardware are compatible platform families. Data centre interconnect roles place the optic between switching blocks that need higher-speed LR links. Campus backbone designs use OS2 grade paths between distribution, aggregation, and edge locations. Aggregation layers use the same optic where port speeds transition from 10G to 25G. Metro handoff designs place the optic in supported Cisco SFP28 ports for longer Ethernet spans. ORM Systems sells SFP-10/25G-LR-S in new and certified refurbished condition for procurement teams.

SFP-10/25G-LR-S Use Case
Campus Distribution Fiber Handoff
SFP-10/25G-LR-S sits in compatible Cisco SFP28 switch ports to carry routed or trunked Ethernet between access aggregation and distribution over G.652 single-mode fiber. The optic presents a 10km LR path where MMF short-reach optics no longer fit the building layout or campus fiber design. Engineers set the host port for the required 10G or 25G operating speed and apply RS-FEC for 25G operation. The result is a longer distribution handoff with the same Cisco optic SKU supporting staged speed migration.
Data Center Leaf Interconnect
SFP-10/25G-LR-S occupies leaf, aggregation, or border switch SFP28 ports where the data center design requires single-mode fiber rather than short copper, DAC, AOC, or MMF reach. Network teams use the dual-rate optic to maintain 10G links during transition phases and move selected paths to 25G as host ports and upstream capacity change. The LC-connected LR link keeps 10km optical reach available across Cisco switching domains. The result is cleaner migration between 10G and 25G without replacing the SMF plant.
Optical Spares Standardization
The operations team holds SFP-10/25G-LR-S as a common spare for compatible Cisco links that require dual-rate 10G or 25G Ethernet over 10km single-mode fiber. The module replaces separate planning for short-reach MMF optics and 25G-only LR optics when the topology already uses SMF and SFP28 host ports. Engineers document LC patching, PC or UPC connector requirements, RS-FEC settings for 25G, and approved Cisco platform support. The result is faster field replacement with fewer optic types in the spares pool.
