With the general over-capacity of fibre in Service Providers' core networks, we are witnessing the use of metropolitan dark fibre being used for point-to-point links over distances of 40km or even further.
Wave Division Multiplexing is opening up far more bandwidth capability for individual fibres, using more than one colour of light to increase the capacity of existing fibres from 1Gbps to multiples of 10Gbps.
Examples of the Wide Variety of Optical Multiplexing Technology from Metrodata.
Metrodata fibre multiplexers offer a variety of ways to converge multiple applications across a single fibre link whether this link is short haul or long haul, singlemode or multimode fibre:
- Emux - Multiple E1 G.703 over Resilient Fibre
- MetroLAN1000 - Multiple E1 G.703 and Ethernet over Fibre
- MetroLAN2000 - Multiple E1 G.703, E3, DS3 and Ethernet over Fibre
- MetroWAVE - Multiple CWDM wavelengths over Fibre
Metrodata fibre multiplexers are supplied as standard with SC or LC 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 either available on request, e.g. ST, FC or can be supported using fibre patch leads.
Vendor compatible fibre transceivers are also available including SFP, SFP+, SFP and XENPAK including long haul and CWDM.
