1.25Gb/s SFP LX Optical Transceiver Module, 1310nm,,20km Reach

Applications
● Gigabit Ethernet data link
● Data storage networks
● Fiber Channel Switch Infrastructure
● Optical access network
● Other optical links
Description
Optcore 1250Mbps SFP LX is a high performance and cost effective optical transceiver module. It is designed to
meet Gigabit Ethernet application. The 1.25G SFP LX optical transceiver consists of two sections: the
transmitter section consists of a high reliability 1310nm FP LD with monitor photo detector (MPD) in eye safety;
the receiver section consists of a high-speed InGaAs PIN photodiode (PD) and trans-impedance preamplifier.
The output of the PD drives the post-amplification, quantizing, and optical signal detection circuits. The receiver
is built in the LOS monitoring function. For further information, please see SFP MSA and SFF-8472 standard.
