CWDM allows the use of a single fibre to transmit up to 40 Km between the main radio unit and the remotes, utilising different wavelengths for transmission over a single fibre. This reduces the need to lay extra fibre cables in the field, which can be labour and material intensive. Additionally, it also enables mobiles equipment to be housed in the telecom exchange rather than in a hut or base station. This may be practical for remote locations or other areas which lack the necessary infrastructure or security. The various interconnection boxes, cables, SFP’s and other hardware offered by WBT, provides mobile network operators with a smooth upgrade path and helps to future proof for upcoming capacity requirements.
