With the general over-capacity of fibre in Service Providers' core networks, higher bandwidth products and services will begin to appear, probably at an economic price. We are witnessing already the use of metropolitan dark fibre being used for point-to-point links from 10, through 100 to 1000 Mbit/s, up to 25 km.
Given fibre access to large corporate's and business parks we shall soon witness a growth in demand for higher than 155Mbit/s. The SDH Fibre-based core networks exist - as soon as the SP's rollout scalable high speed services, 622Mbit/s will appear.
Wave Division Multiplexing (WDM) will open up far more bandwidth capability for individual fibres, by using more than one colour of light to increase the capacity of existing fibres.

Metrodata fibre converters offer conversion to singlemode short haul fibre, singlemode long haul fibre and multimode fibre from:
- E1 G703 BNC/RJ45 interface
- E3/DS-3 G.703 interface
- STM-1/OC-3 interface
- Multimode Fibre interface
- Async RS232
- EIA 530, V.35, V.36, X.21, Synchronous RS232
- Ethernet - see Ethernet media converters
All Metrodata fibre converters are supplied as standard with SC connectors operating at a nominal wavelength of 1300nm. Other wavelengths are available on request, e.g. 850nm, 1550nm, 1550/1300 WDM, CWDM. Other connectors are available on request, e.g. ST, FC.
Select your application from the tabs below:
Extend both voice (e.g. PBX) and data services (e.g. Router with E1 G.703 interface) over multimode or singlemode fibre.
Extend your E3/DS3 services over extended distances using multimode or singlemode fibre.
Extend RS232 Asynchronous Data over Fibre at Rates up to 256kbps
