Cisco SFP-10G-LR Compatible - 10GBASE-LR SFP+ 1310nm 10km DOM LC SMF Transceiver Module


Category : Data Center Networking
Brand : Cisco
Model : SFP-10G-LR=


The Cisco® 10GBASE SFP+ modules (Figure 1) give you a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications.

Features and benefits

Cisco SFP+ modules offer the following features and benefits.

  • Industry’s smallest 10G form factor for greatest density per chassis
  • Hot-swappable input/output device that plugs into an Ethernet SFP+ port of a Cisco switch (no need to power down if installing or replacing)
  • Supports “pay-as-you-populate” model for investment protection and ease of technology migration
  • Digital optical monitoring capability for strong diagnostic capabilities
  • Optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link
  • Cisco quality Identification (ID) feature enables a Cisco platform to identify whether the module is certified and tested by Cisco

The Cisco 10GBASE-LR Module supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF, G.652).
