SFP+ 10G ELR Single Mode Fiber SMF 20km Optical Transceiver Module 1310nm LC DDM
SFP+ 10G eLR 20km SMF Transceiver Module LC DOM
Description
The 10G eLR transceiver module is designed for use in 10 Gigabit Ethernet links up to 20km over dual strand single mode fiber (SMF) with an LC duplex connector. They are compliant with SFF-8431, SFF-8432 and IEEE 802.3ae.
The 10G eLR SFP+ transceiver consists of two sections: the transmitter section uses a 1310nm multiple quantum well DFB laser and is a class 1 laser compliant according to International Safety Standard IEC-60825, the receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.
Digital diagnostics monitoring is available via a 2-wire serial interface, as specified in SFF-8472.
Featuring low power consumption and high speed, this 10G SFP+ transceiver is ideal for 10 Gigabit Ethernet (10GbE) Switches,Routers,Network Interface Cards (NICs) and Media Converters,etc.
Each transceiver is 100% optically inspected and tested before shipping.
