Optical transceiver extends copper's reach

A new four-channel optical transceiver extends the signal transmission reach of a copper interface up to 300m at 2.5Gbit/s or 100m at 3.125Gbit/s over multimode fibre ribbon cable.

A new four-channel optical transceiver module uses an internal media convertor to extend the signal transmission reach of a copper interface up to 300m at 2.5Gbit/s or 100m at 3.125Gbit/s over multimode fibre (MMF) ribbon cable.

Using the Fujitsu optical module, IT managers have the flexibility to implement either a copper or an optical solution using one low-cost copper I/O interface.

Applications include connections between systems in telecomms central offices and data centres; as well as in-system interconnects in routers, switches and transmission equipment.

The hot-pluggable optical module's high-speed electrical socket is based on Fujitsu's industry-standard microGiGaCN differential copper I/O connector.

The module works seamlessly with Fujitsu's XAUI-based 10Gbit Ethernet copper Xenpak modules and other industry-standard MDI electrical sockets for CX4, InfiniBand and Fibre Channel.

The optical module has 0.8W typical power dissipation and a case operating temperature range of 0 to +70C.

A media detect circuit is required on the host system to power the convertor and the module has LED indicators.

Other 10Gbit Ethernet products in the microGiGaCN line include: X2 CX4 modules in lowpak, midpak and highpak form factors with an integrated media detect circuit; and copper CX4 Xenpak modules with an integrated media detect circuit.

Both the X2 CX4 and CX4 Xenpak modules deliver 10Gbit/s Ethernet over 15m copper cable or VSR parallel optics through a single port.
