Description

  The Bi-Directional transceiver is a high performance, cost effective module ,which is compliant with LC Optics interface with built in WDM for Bi-Directional serial optical data communication applications. This module is designed for Single-Mode single fiber, operates at the normal wavelength of 1310/1490nm.

Standard AC coupled CML for high speed signal and LVTTL control and monitor signals.

The transmitter section incorporates FP and driver IC with temperature compensation and automatic power control circuit, which make the transmitter section output power and Extinction ration stabled in operation temperature.

The receiver section incorporates an efficient InGaAs photodiode and transimpedance with AGC for wide dynamic range.
