1 / 18 page  HFBR-7934Z and HFBR-7934EZ/HZ/EHZ Four-Channel Pluggable Parallel Fiber Optic Transceiver Data Sheet Description The HFBR-7934Z transceiver is a high performance fiber optic module for parallel optical data communication applications. It incorporates 8 independent data channels (4 for transmit and 4 for receive) operating from 1 to 3.125 Gb/s 8B/10B encoded per channel providing a cost effective solution for very short reach applications requiring 12.5 Gb/s aggregate bandwidth. The module is designed to operate on multimode fiber systems at a nominal wavelength of 850 nm. It incorporates high performance, highly reliable, short wavelength optical devices coupled with proven circuit technology to provide long life and consistent service. The HFBR-7934Z transceiver module incorporates a 4 channel VCSEL (Vertical Cavity Surface Emitting Laser) array together with a custom 4 channel laser driver integrated circuit providing IEC-825 and CDRH Class 1M laser eye safety. It also contains a 4 channel PIN photodiode array coupled with a custom preamplifier / post amplifier integrated circuit. Operating on 3.3 V power supply this module provides LVTTL/LVCMOS control interfaces and CML compatible high speed data lines which simplify external circuitry. The transceiver is housed in MTP®/MPO receptacled package with integral finned heatsink. Electrical connections to the device are achieved by means of a pluggable 10x10 connector array.
