E1/T1 G.703 to 70km Singlemode Fibre Converter
The Metrodata FC1200 product provides a high performance solution for extending and interconnecting voice and data communication infrastructures using singlemode fibre optic cabling. Both North American T1 standards and European E1 standards are supported. 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 a cost 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 1.5Mbps over multimode fibre up to 5km
- FC1100: E1 2Mbps G.703 or T1 1.5Mbps over singlemode fibre up to 30km
- FC1200: E1 2Mbps G.703 or T1 1.5Mbps over singlemode fibre up to 70km
Using fibre optics the FC1200 extends the operating distance of an E1/T1 G.703 interface whether on a router, PBX or similar equipment over singlemode fibre. The FC1200 is totally transparent to both payload and protocol and as such will support unframed or framed data such as E1 G.704, ISDN PRI, 2Mbps G.703, T1 PRI and 23B+D.
The maximum operating distance of the FC1200 is 70km, although 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 standard FC1200 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 FC1200 E1 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 FC1200 has an integral mains or 40 volt power supply, and can be desktop or rack-mounted. The FC1200 can easily be rack mounted in either a1U two unit rack mount kit, a 6U eighteen unit rack mount kit.
The FC1200 is also available in a card based format for use with the 4U 12-slot MetroCONNECT managed chassis.
The FC1200 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.
