622Mbps Singlemode to Multimode Fiber Converter

The FC6500 provides a new level of performance for connecting switches and routers to carrier singlemode fibers. As the demands for on-site communication increase, especially in the IP arena, fibre cable becomes the attractive solution in capacity, cost and quality.

Singlemode Long Haul to Multimode Fibre Converter

  • Simple single mode to multi mode conversion at 622Mbps
  • Use instead of expensive singlemode router interfaces
  • Zero configuration required - just plug & go
  • Easy to install & maintain
  • Integral auto-sensing power supply (100-250V AC or -40V DC versions)
  • 12-24V DC power supply available on request
  • External alarm relay port
  • Compact modem style unit, built to European standards
  • Rack mounting kits for 2 or 18 units available

High capacity routers, ATM switches and other CPE increasingly need to be interconnected by high-speed fibre links, and except within buildings most fibre installations are singlemode for performance reasons. However singlemode interfaces on CPE such as routers are inherently expensive, and so it is generally more cost effective to use a multimode CPE interface along with the Metrodata FC6X00 multimode to singlemode converter.

With the need to extend, or interconnect, communication infrastructures over greater distances, the Metrodata FC6X00 Fiber Converter product range provides a cost effective solution for the extension of STM-4/OC-12 (622Mbps) services.

There are two models in the range:

  • FC6000: 622Mbps multimode to singlemode fibre up to 30km
  • FC6500: 622Mbps multimode to singlemode fibre up to 70km

Using fibre optics the FC6500 extends the operating distance for a 622Mbps multimode fibre to 70km using singlemode fibre. Despite these quoted maximum operating distances for the FC6X00 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 FC6X00 products are totally transparent to both payload and protocol, and as such will convert whatever information at 622Mbps is contained within the light stream from one fibre mode to the other. It requires NO configuration and has a single LED for status.

The standard FC6X00 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 FC6X00 has integral mains or 40 volt power supply, and can be desktop or rack-mounted. The FC6X00 range can easily be rack mounted in either a 1U two unit rack mount kit, a 6U eighteen unit rack mount kit.

The FC6X00 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.

FC6500: multimode to long haul singlemode converter
FC6500 622Mbps STM-4/OC-12 Multimode to Long Haul Singlemode Fibre Converter

This application shows how a pair of FC6500 units can be used to extend an STM-4/OC-12 connection between two routers over long haul singlemode fibre. The FC6500 is a zero configuration, plus & play device. This singlemode fibre could be across a city, or between cities (e.g. over a rented fibre).
