Optcore’s OSP10G-311DxR is a high performance and cost-effective 10GBASE-LR lite SFP+ transceiver module for
10 Gigabit Ethernet links up to 1.4km over single mode fiber.

SKU: STI-OSP10G-311DCR Category:


The transceiver features a highly reliable 1310nm FP
transmitter and PIN photo-detector into duplex LC optical connector. It complies with SFP+ MSA specifications
(SFF-8431, SFF-8432), 10 Gigabit Ethernet specifications (10GBASE-LR/LW per IEEE 802.3ae ), and 10G Fibre
Channel (1200-SM-LL-L). It’s suitable for use in 10G Ethernet switches, routers, network interface cards (NICs), fiber
media converters and storage networking equipment. Additionally, the 10GBASE-LR lite SFP+ 2km transceiver has been integrated with an enhanced digital diagnostic
monitoring interface (DDMI) per SFF-8472, which provides real-time monitoring of the transceiver temperature, laser
bias current, optical power, received optical power and transceiver supply voltage. All transceivers are Class 1 laser
products comply with FDA/CDRH and IEC-60825 standards. There are three versions of the series 10GBASE-LR lite SFP+ 2km transceiver for different applications. The Standard
grade (0~70ºC) is for commonly commercial application, the Extended grade (-10~85ºC) is for Extended temperature
application, and the Industrial grade (-40~85ºC) is made with robust and reliable components to meet the needs of
Industrial Ethernet application under harsh environmental conditions.
