摘要： In order to increase the capacity of a deployed passive optical network (PON) without replacing optical network terminators (ONTs), a PON is provided that is partitioned into multiple channels. The upstream and downstream channels in the PON are partitioned into M channels, with the number of channels on the upstream preferably equaling the number of channels on the downstream. In the downstream, the partitioning is accomplished by use of wavelength division multiplexing filters arranged in a way as to place groups of ONTs on M different wavelength bands, where all of the wavelength bands are within the downstream wavelength range of the existing PON. On the upstream, partitioning is accomplished using "injection locking" to narrow the possible wavelength range of each ONT transmitter to a portion of that possible in the existing PON.
