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.
