E1 / T1 to Fibre Converter
The Metrodata FC1X00 product family provides a high performance solution for extending and interconnecting E1 2Mbps G.703/G.704 and T1 1.544Mbps voice and data communication infrastructures using fibre optic cabling. This is an alternative product for the Probot 3005 E1 Fibre Modem.

With the need to extend, or interconnect, communication infrastructures over greater distances, and the cost of fibre falling dramatically, the Metrodata FC1X00 Fibre Converter product range provides an effective solution for the extension of E1 (2.048Mbps) or T1 (1.544Mbps) services.
There are three models in the range:
- FC1000: E1 2Mbps G.703 or T1 1.544Mbps over multimode fibre up to 5km
- FC1100: E1 2Mbps G.703 or T1 1.544Mbps over singlemode fibre up to 30km
- FC1200: E1 2Mbps G.703 or T1 1.544Mbps over singlemode fibre up to 70km
Using fibre optics the FC1X00 products extend the operating distance for a E1 2Mbps or T1 1.544Mbps G.703 interface to 5km using multimode fibre, or to either 30km or 70km using singlemode fibre. Despite these quoted maximum operating distances for the FC1X00 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 FC1X00 products are totally transparent to both payload and protocol and as such will support unframed or framed data such as G.704, ISDN PRI, T1 or E1.
The standard FC1X00 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 FC1X00 G.703 connection is configurable between twin BNC coaxial connectors or a single RJ45. The G.703 interface supports direct connection to equipment such as Routers or PBXs, however a cross-over cable must be used to connect to an NTU.
The FC1X00 has integral mains or 40 volt power supply, and can be desktop or rack-mounted. The FC1X00 range can easily be rack mounted in either a 1U two unit rack mount kit, a 6U eighteen unit rack mount kit.
The FC1X00 is also available in a card based format for use with the 4U 12-slot MetroCONNECT managed chassis.
The FC1X00 is part of a range of fibre conversion products from Metrodata. The wider product range offers fibre conversion solutions ranging from 300 baud RS-232, via Nx64kbps rates, through 2Mbps and up to 155Mbps for electrical to fibre conversion; or 155Mbps, 622Mbps or Gigabit Ethernet for fibre mode or wavelength conversion.

This application shows a pair of PBX systems connected over a multimode fibre using a pair of FC1000 units. This multimode fibre could be within a building (e.g. between two PBXs at either end of a large hotel), or across a campus (e.g. between two departmental buildings of a University).

This application shows a PBX being remotely connected to an NTE over a multimode fibre using a pair of FC1000 units. This multimode fibre could be within a building (e.g. between a PBX and a switch room at either ends of a building), or across a campus (e.g. between two departmental buildings of a University).

This application shows a pair of routers connected over a singlemode fibre using a pair of FC1100 units. This singlemode fibre could be between buildings (e.g. across a business park), or across a city (e.g. over a rented fibre).

This application shows an E1 router being remotely connected to an NTE over a singlemode fibre using a pair of FC1100 units. This singlemode fibre could be between buildings (e.g. across a business park), or across a city (e.g. over a rented fibre). Similarly T1 routers can also be connected over a singlemode fibre using a pair of FC1100 units.

This application shows an E1 router being remotely connected to an E1 G.703 satellite modem over a longhaul singlemode fibre using a pair of FC1200 units. This singlemode fibre could be across a city, or between cities (e.g. over a rented fibre).
