DescriptionThe HFBR-56xx/HFCT-56xx family of interface converters meet the Gigabit Interface Converter specification Rev. 5.4, an industry standard. The family provides a uniform form factor for a wide variety of standard connections to transmission media.
The HFBR-56xx/HFCT-56xx converters can be inserted or removed from a host chassis without removing power from the host system. The converters are suitable for interconnections in the Gigabit Ethernet hubs and switches environment. The design of these converters is also practical for other high performance, point-topoint communication requiring gigabit interconnections. Since the converters are hot-pluggable, they allow system configuration changes simply by plugging in a different type of converter.
The mechanical and electrical interfaces of these HFBR-56xx/HFCT-56xx converters to the host system are identical for all implementations of the converter regardless of external media type. A 20-pin connector is used to connect the converter to the host system. Surge currents are eliminated by using pin sequencing at this connector and a slow start circuit. Two ground tabs at this connector also make contact before any other pins, discharging possible componentdamaging static electricity. In addition, the connector itself performs a two-stage contact sequence. Operational signals and power supply ground make contact in stage 1 while power makes contact in stage 2.
The HFBR-56xx/HFCT-56xx has been developed with 850 nm short wavelength VCSEL technology while the HFBR-56xx/HFCT-56xx is based on 1300 nm long wavelength Fabry Perot laser technology.
