Legacy STM-1/OC-3 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 STM-1/OC-3 BNC electrical equipment to STM-1/OC-3 fibre equipment.
There are three models in the range:
- FC4000: 155Mbps STM-1/OC-3 G.703 BNC electrical to 5km multimode fibre converter
- FC4100: 155Mbps STM-1/OC-3 G.703 BNC electrical to 30km singlemode fibre converter
- FC4200: 155Mbps STM-1/OC-3 G.703 BNC electrical to 70km singlemode fibre converter
Using fibre optics the FC4X00 products extend the operating distance for a 155Mbps electrical signal to 5km using multimode fibre or to either 30km or 70km using singlemode 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.
The FC4X00 is also available in a card based format for use with the 4U 12-slot MetroCONNECT 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.
Applications
- Interfacing between multimode and electrical BNC ports operating at 155Mbps STM-1/OC-3
- Interfacing between a 155Mbps STM-1/OC-3 electrical BNC port and a singlemode leased line service
- Interfacing between a 155Mbps STM-1/OC-3 electrical BNC port and a long haul singlemode leased line service
This application shows how a 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).
This application shows how a FC4100 unit can be used to interface between a legacy switch with 155Mbps STM-1/OC-3 electrical BNC ports and a standard STM-1/OC-3 leased line circuit delivered over singlemode fibre. 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 singlemode fibre could be between buildings (e.g. across a business park), or across a city (e.g. over a rented fibre).
