Pdr manufactures fiber optic transceiver. It is a high performance and cost effective module which is used for serial optical data communication applications. This module is designed for single mode fiber operation at the wavelength of 1310nm to 1550nm or multi-mode fiber operation at the wavelength of 850nm to 1310nm. The transmitter section incorporates an advance fp / dfb laser for single-mode or vcsel for multi-mode. There is temperature compensation and automatic power control circuit. The salient features of fiber optic transceiver:
