Optical and TDM / SDH Multiplexers

Metrodata offer a variety of different products for multiplexing various services, using a variety of underlying technologies, such as Fibre, TDM and SDH.

These conversions are performed transparently and so are independent of protocol or router configuration. Comprehensive management functionality is also offered in our powered devices which allows the full range of monitoring and configuration control via either local or remote management. Devices can be managed locally using a terminal, or remotely using Telnet or SNMP via an IP network or in band management.

Metrodata's passive CWDM and DWDM Multiplexer family, MetroWAVE, offers a highly effective solution to enable Service Providers to maximise the bandwidth of dark-fibre links. Multiple different services, typically each of up to 10Gbps (even some 40Gbps), are run across conventional single-mode fibre links using different wavelengths. CWDM (Coarse Wavelength-Division Multiplexing) offers up to 16 different wavelengths for running different services, and this number can be increased by moving to or simply adding DWDM (Dense Wavelength-Division Multiplexing) wavelengths. Metrodata offers both CWDM and DWDM multiplexers, which have the added advantage of being totally passive in operation, which being completely unpowered are extremely reliable in operation, as well as being small, light and competitively priced.

Our MetroWAVE multiplexers are also used by Corporate and Public Sector customers, wherever multiple high-bandwidth or simply diverse services (e.g. Voice, Serial communications, Ethernet data and/or Telemetry) need to be transported across a single conventional fibre link. Metrodata offers a wide range of fibre media converters and fibre modems for different communications protocols, which can be used in conjunction with the MetroWAVE family.

Typical Example of use: Extending Voice and Data services
Typical Example of use: Extending Voice and Data services from a primary site to remote sites
  • Emux: products are typically used to multiplex ISDN30 and PBX Voice Trunks and Data from one location to another. This offers a simple method of delivering 4, 8 or 16 E1 services over single, dual or redundant fibre.

The MetroLAN product range multiplexes multiple Ethernet, E1, T1, E3 and DS3 services onto STM-1/OC-3 services (or fibre) using SDH technology.

  • MetroLAN1000: offers a sophisticated solution to the convergence of multiple Ethernet, E1 and T1 equipment using SDH multiplexing technology
  • MetroLAN2000: offers a sophisticated solution to the convergence of multiple Ethernet, E1, T1, E3 and DS3 equipment using SDH multiplexing technology
