Description
The MXPD-243S transceiver is a high performance, cost effective module that supports data-rate up to 1250Mbps.
The transmitter section and the receiver section work independently in the transceiver. The receiver section contains an InGaAs PIN photo diode, a transimpedance amplifier and a post amplifier (with working data rate up to 1250Mbps), functionally transmit received optical power to steady electrical data.
This transceiver meets the Small Form Pluggable (SFP) industry standard package utilizing an integral LC-Duplex optical interface connector. An enhanced Digital Diagnostic Monitoring Interface compliant with SFF-8472 has been incorporated into the transceiver. It allows real time access to the transceiver operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage by reading a built-in memory with I
