Structure of CWDM SFP transceiver
The CWDM SFP transceiver consists of three sections: a uncooled CWDM DFB laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit.

The transceiver integrates the receive and transmit path on one module. On the transmit side, the serial data stream is passed to a laser driver. The laser driver biases and modulates an uncooled direct modulated laser (DML), enabling data transmission over single-mode fiber through an industry-standard LC connector. On the receive side, the optical data stream is recovered from a PIN or avalanche photodetector (APD), sent to a transimpedance amplifier, and then passed to a post amplifier. This module features a hot-pluggable SFI-compliant electrical interface.

This integrated fiber optic transceiver provides a high-speed serial link at signaling rates from 100 Mbps to 3.1 Gbps. The module complies with the small form factor pluggable (SFP) multisource agreement (MSA).
