This application shows how an FC4000 unit can be used to interface between a router with a 155Mbps STM-1/OC-3 port and a switch supporting 155Mbps STM-1/OC-3 electrical BNC connectivity. In this way historic Telecom switches with 155Mbps STM-1/OC-3 electrical BNC interfaces can be re-used in modern fibre based infrastructures, reducing costs and gaining benefits from the features of both legacy and modern equipment. This multimode fibre could be within a building (e.g. in a switch room or exchange), or across a campus (e.g. between two departmental buildings of a University).
Legacy OC-3/STM-1 155Mbps equipment is often fitted with G.703 BNC electrical interfaces. The FC4X00 product family enables connection of this equipment across fibre.
The FC4X00 product family also enables connection of OC-3/STM-1 BNC electrical equipment to OC-3/STM-1 fibre equipment.
There are three models in the range:
- FC4000 155Mbps OC-3/STM-1 G.703 BNC electrical to 5km multimode fibre converter
- FC4100 155Mbps OC-3/STM-1 G.703 BNC electrical to 30km single mode fibre converter
- FC4200 155Mbps OC-3/STM-1 G.703 BNC electrical to 70km single mode fibre converter
Using fibre optics the FC4000 extends the operating distance for a 155Mbps electrical signal to 5km using multimode fibre. Despite these quoted maximum operating distances for the FC4X00 products, specific installations may only operate over lower distances due to the variations in losses of different types of fibre cable, the use of connecting fibre cables, or patch panels. When operating over 50% of the maximum distances it is advisable to calculate all fibre optic connector and cable losses and compare these with the fibre optic loss budget specified for this product.
The FC4X00 products are totally transparent to both payload and protocol, and as such will convert whatever information at 155Mbps is received from one fibre mode to the other. It requires minimal configuration and has a single LED for status.
The standard FC4X00 is supplied with SC fibre connectors and operates at a nominal wavelength of 1300nm. Other wavelengths are available on request, e.g. 850nm, 1550nm, 1550/1300 WDM. Other connector options are also available on request, e.g. ST, FC.
The FC4X00 has integral mains or 40 volt power supply, and can be desktop or rack-mounted. The FC4X00 range can easily be rack mounted in either a 1U two unit rack mount kit, a 6U eighteen unit rack mount kit or is available as a 1U quad box (which contains 4 x FC4X00 units).
The FC4X00 is also available in a card based format for use with the 4U 12-slot MetroRack managed chassis.
The FC4X00 is part of a range of fibre conversion products from Metrodata. The wider product range offers fibre conversion solutions ranging from 2Mbps up to 155Mbps for electrical to fibre conversion, or 155Mbps, 622Mbps or Gigabit Ethernet for fibre mode or wavelength conversion.
