Abstract
Methods and apparatuses to provide wavelength locked WDM Passive Optical Networks ('PONs') are described. A first transceiver transmits a set of optical signals in a first direction along a wavelength channel. A second transceiver transmits another set of optical signals along the same wavelength channel in another direction. The wavelength of the first transceiver is locked using an optical power of the optical signals of the second transceiver. The wavelength of the second transceiver is locked using the optical power of the optical signals of the first transceiver. A WDM MUX/De-MUX is coupled between the first transceiver and the second transceiver. An in-line gain element can be coupled to the WDM MUX/De-MUX to amplify the optical signals. The first transceiver and the second transceiver operate in a saturated gain condition.
