The transmitter section of the AFBR-53B3EZ consists of an 850 nm Vertical Cavity Surface Emitting Laser (VCSEL) in an Optical Subassembly (OSA), which mates to the fiber cable. The OSA is driven by a custom, silicon bipolar IC which converts diff erential PECL compatible logic signals into an analog laser diode drive current. The high speed output lines are internally ac-coupled and diff erentially terminated with a 100 Ω resistor.
The receiver of the AFBR-53B3EZ includes a GaAs PIN photodiode mounted together with a custom, silicon bipolar transimpedance preamplifi er IC in an OSA. This OSA is mated to a custom silicon bipolar circuit that provides postamplifi cation and quantization.
The post-amplifi er also includes a Signal Detect circuit which provides a PECL logic-high output upon detection of a usable input optical signal level. This single-ended PECL output is designed to drive a standard PECL input through a 50 ohm PECL load. The high speed output lines are dccoupled, diff erent from the transmitter.
