Description The HFBR-53A5VEMZ transceivers from Avago Technologies allow the system designer to implement a range of solutions for multimode Gigabit Ethernet applications.
The overall Avago transceiver product consists of three sections: the transmitter and receiver optical subassemblies, an electrical subassembly, and the package housing which incorporates a duplex SC connector receptacle.
The transmitter section of the HFBR-53A5VEMZ/FMZ 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 differential PECL compatible logic signals into an analog laser diode drive current. The high speed output lines are internally accoupled and differen-tially terminate with a 100 Ω resistor.
The receiver of the HFBR-53A5VEMZ/FMZ includes a GaAs PIN photo-diode mounted together with a custom, silicon bipolar transimpedance preamplifier IC in an OSA. This OSA is mated to a custom silicon bipolar circuit that provides post-amplification and quantization.
The post-amplifier also includes a Signal Detect circuit which provides a TTL logic-high output upon detection of a usable input optical signal level. The high speed output lines are internally ac-coupled.
