Function description:
The fiber optic transceivers offer a simple, convenient way to interface PCBs to single -mode fiber optic cables and integrate WDM (Wavelength Division Multiplex) coupler. Many performance versions are available which are fully compliant with SONET/SDH standards from and international IEC-825 standards.
The transmit and receive functions are contained in a single one-row, 9-pin (1x9) package with a Single SC or ST or FC connector interface. The transmitter incorporates a highly reliable 1310 nm or 1550 nm Laser and a driver circuit which converts Pseudo Emitter Coupled Logic (PECL) data to light. The receiver incorporates an efficient InGaAs/InP PIN photodiode converting the light signal into an electrical current which is amplified and regenerated into PECL-compatible data. The transimpedance amplifier IC has internal AGC for wide dynamic range. A Signal Detect status output flag is also provided.
The transceiver operates from a single +5V or +3.3V power supply over an operating temperature range of - 40C to +85C. The transceiver package is made of either conductive plastic (Single-SC) with black color or metal (FC and ST and SC) for excellent EMI shielding.
