Abstract: A method for managing optical transceivers includes obtaining laser measurements for a laser operating in an optical transceiver in a network device, obtaining a failure profile for the laser, making a first determination that the laser measurements match the failure profile, and based on the first determination, initiating a remediation action for the optical transceiver.

Abstract: A semiconductor optical amplifier (SOA) receives a multiwavelength input optical signal and amplifies the multiwavelength input optical signal to generate an amplified multiwavelength optical signal. A waveguide is coupled to receive the amplified multiwavelength optical signal. The waveguide includes an enhanced chromatic dispersion segment configured to increase chromatic dispersion experienced by the multiwavelength optical signal as the multiwavelength optical signal propagates through the waveguide and is amplified by the SOA. This increase in chromatic dispersion reduces noise, such as four-wave mixing noise, in the amplified multiwavelength optical signal.

Abstract: Embodiments of the present disclosure include optical transmitters and transceivers with improved reliability. In some embodiments, the optical transmitters are used in network devices, such as in conjunction with a network switch. In one embodiment, lasers are operated at low power to improve reliability and power consumption. The output of the laser may be modulated by a non-direct modulator and received by integrated optical components, such as a modulator and/or multiplexer. The output of the optical components may be amplified by a semiconductor optical amplifier (SOA). Various advantageous configurations of lasers, optical components, and SOAs are disclosed. In some embodiments, SOAs are configured as part of a pluggable optical communication module, for example.
