Overview

SFP-10G-LR-S supports links up to 10 km on standard G.652 single-mode fibre, with a 2 m minimum. It uses a duplex LC/PC connector, draws 1 W, carries a blue bail latch and supports digital optical monitoring. It is rated for the commercial temperature range of 0 to 70°C.

S-class is Cisco's Ethernet-focused version of this module. Cisco publishes the same optical specifications, reach, power and temperature rating for SFP-10G-LR-S and SFP-10G-LR; the documented difference is that the S-class module does not support FCoE (Fibre Channel over Ethernet).

Typical uses

  • Building to building campus links
  • Data hall and inter-row 10G links
  • Metro and service provider access up to 10 km

Questions about the SFP-10G-LR-S

What is the difference between SFP-10G-LR-S and SFP-10G-LR?
Cisco lists both with the same wavelength, reach, power, temperature rating and bail colour. The S-class module does not support FCoE; the standard module carries no such restriction. For plain Ethernet links they connect to each other and to other 10GBASE-LR optics.
Will it work in my switch?
It fits Cisco SFP+ ports on Catalyst, Nexus, ASR, ISR and other platforms. Check the exact host and minimum software release in Cisco's transceiver compatibility tables before ordering.
Do I need an attenuator on short links?
No. Cisco's data sheet specifies attenuators only for ER and ZR modules. 10GBASE-LR is specified from 2 m up to 10 km.
How quickly can you confirm availability?
Listed availability shows when supply was last verified. For other quantities or destinations, send a request and we confirm supply and price in writing.
