Communication over single fibre

Did you know Westermo ODW serial to fibre modems support communications over a single fibre?

Typically, communication over fibre requires two separate fibre cores for full duplex communications. But in some applications there is only a single fibre available. This may be due to a broken fibre core or there is only one core left in a multicore. The ODW-7xx fibre modems can solve this issue when matched with a Westermo Bi-Directional (BiDi) transceiver.

The BiDi transceiver uses two different wavelengths of laser light. One in each direction to transmit and receive data simultaneously. The different wavelengths of light are in effect isolated from each other so it cannot cause interference or errors in the data flowing in each direction. The use of BiDi transceivers can save costly replacements or increase the number of data services over an existing fibre cable.
