Embodiment Construction
[0030] figure 1 A schematic diagram of an adjustable ONU transceiver according to an embodiment of the present invention is shown. This adjustable ONU transceiver 1 includes an optical coupler 10, a bidirectional amplifier 11 (such as SOA), a comb filter 12, two optical circulators (the first optical circulator 13 and the second optical circulator 14), a light source 15 And downlink receiver 16. Preferably, FP-LD or RSOA can be used as the light source. In one embodiment of the invention, the optocouplers are arranged 80:20. It should be understood that in practice, the above ratios can be changed to other values (eg 90:10 etc.) depending on the parameters in the construction.
[0031] In this scheme, the tunable ONU transmitter and receiver are interrelated by sharing the same bidirectional amplifier 11 and comb filter 12, and thus greatly saves the cost of the ONU. The uplink wavelength is generated through a feedback loop, which includes an optical coupler 10 , a bidi...
