The HFBR-2531Z with Fibre Optic Transmitters, Receivers, Transceivers manufactured by Broadcom is a vertical 5 Mbit/s transceiver designed for high speed transmission of data over fibre optic cable. The device operates at a wavelength of 1310 nm, has a rise time of 140 ns and a fall time of 145 ns. It is RoHS compliant and is capable of realising data speeds of up to 100 MBytes/s over short distances. It is also useful for long distance data transmission, as it has a distance of up to 30 km when used with Single-mode fibre or up to 500 m when used with Multi-mode fibre. The device can be used in local area networks (LANs), metropolitan area networks (MANs) and wide area networks (WANs). It is suitable for use in applications such as network switching, optical test equipment, and medical instrumentation.
