HFCT-53D5

HFBR-53D5 Family, 850 nm VCSEL HFCT-53D5 Family, 1300 nm FP Laser 1 x 9 Fiber Optic Transceivers for Gigabit Ethernet Data Sheet Description The HFBR/HFCT-53D5 transceiver from Avago Technologies allows the system designer to implement a range of solutions for multimode and single mode Gigabit Ethernet applications. The overall Avago Technologies 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. Transmitter Section The transmitter section of the HFBR-53D5 consists of an 850 nm Vertical Cavity Surface Emitting Laser (VCSEL) in an optical subassembly (OSA), which mates to the fiber cable. The HFCT-53D5 incorporates a 1300 nm Fabry-Perot (FP) Laser designed to meet the Gigabit Ethernet LX specification. The OSA is driven by a custom, silicon bipolar IC which converts differential PECL logic signals (ECL referenced to a +5 Volt supply) into an analog laser diode drive current. Receiver Section The receiver of the HFBR-53D5 includes a silicon PIN photodiode 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 HFCT-53D5 utilizes an InP PIN photodiode in the same configuration. The post-amplifier also includes a Signal Detect circuit which provides a PECL logic-high output upon detection...
