摘要： A directly modulated multi-electrode DFB laser is used to transmit information in a TWDM environment where the output power and the output wavelength of the laser output signal are determined by the ratios of bias currents simultaneously applied to the electrodes of the laser by a control circuit. The total amount of current applied to the electrodes is kept to a constant value to maintain the temperature of the laser constant. The electrodes of the DFB laser are positioned so as not to experience any thermal coupling between them or with any other component of the DFB laser.

摘要： A manner of mitigating the self heating effect of a laser or other light source such as a laser in a network node of a communication network. A self-heating mitigation module is provided, the self-heating mitigation module includes one or both of a self-heating adjustment module to accelerate self heating at the beginning of a transmission and a sub-threshold lasing module that applies a sub-threshold current between transmissions. The self-heating adjustment module and the sub-threshold lasing module are preferable both used together and driven by a common signal, for example the burst_enable signal that facilitates transmission from the light source.

摘要： An optical line terminal transmitter front-end, an optical network terminal receiver front-end and a bit-interleaved passive optical network (BIPON). In one embodiment, the transmitter front-end includes: (1) a bit interleaver configured to group and interleave a plurality of user bit-streams to yield a combined single bit-stream, (2) an encoder coupled to the bit interleaver and configured to encode multiple bits of the single bit-stream into a multi-level code corresponding to a 2m-level multi-level signal and (3) a multi-level modulator coupled to the encoder and configured to modulate the multi-level code into the 2m-level multi-level signal.
