Cisco SFP-10G-LR module is the single-mode 10G fiber optical transceiver, the Cisco 10G Base-LR Module supports a link length of 10 kilometers on standard single-mode fiber (SMF, G.652) and SFP-10G-LR SFP Plus optical transceiver from Solid-Optics offers up to 10Km link length on standard single-mode fiber. 

The Features

Figure 1. The appearance of SFP-10G-LR.
   ☆ 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
   ☆ 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
