The wall box is modularly constructed and can therefore be delivered in various sizes based on a basic unit and 1 or more extension units. The basic unit can hold up to 24 LC connectors. An extension unit must be used for CWDM 18.
- Passive optical multiplexer/de-multiplexer.
- Increases the capacity of existing networks by transferring several wavelengths on the same fibre.
- Independent of protocol and bitrate.
- Delivered in several combinations from 4 to 18 channel CWDM.
- DIN-rail mount or directly on wall.
- Simple access inside panel.
- May be extended with add-on units.
Passive CWDM units are a reliable and reasonable method for transferring several wavelengths/signals over the same fibre (wavelength multiplexing). In this way you may increase the capacity of existing fibre-cable significantly. Combined with OADM you may add or drop wavelengths on the way between the end points. A big advantage of using passive wavelength multiplexing is also that the method is protocol– and bitrate independent.
A complete system with components for two-way communication (multiplexer and de-multiplexer) in both ends are made using two units.

The DIN panel may be delivered with adapters, pigtails or pre-terminated cable type AXAI, QXXI or Micro-cable. AXAI have tight buffer and up to 24 fibre, a panel with 48 fibre will therefore be delivered with 2 cables. The panel may also be delivered with CWDM multiplexer and de-multiplexer. Two panels (one at each end of the link) will then make a complete system with necessary components for duplex communication. All connectors (both in and out) are at the front.
The DIN-rail clip is mounted in the back, on the short side. By using a bracket (not included) the panel may be mounted with the long-side towards the wall - either by using the DIN-clip or by screwing it directly to the wall. The same bracket enables you to place the panel on a standard flush-mounted wall-box (has C/C 60 mm key holes and opening for cables). The included plastic DIN-clip may be changed to a metal DIN-clip (not included) if required.
Both the units and the lid is hinged at the top to make it easy to work inside all units without taking everything apart. This also helps avoiding damage to the fibre because the units are opened and closed in a controlled way. The hinges are snap-locks, this enables the units to be fully disconnected without the use of any tools. The adapter plate may also be removed by loosening similar snap-locks.
