摘要： A method is provided to lower the overall power consumption of small form-factor pluggable (SFP) transceivers. The method includes receiving an indication to operate the SFP transceiver in a low power mode, and setting the SFP transceiver to a low power mode in response to the indication by at least switching off a thermal electric cooler (TEC) that controls a temperature of a laser diode of the SFP transceiver. The proposed method may be implemented whenever a reach is not more than a predetermined distance, for example, 65 kilometers. At such reduced distances, the TEC of the SFP transceiver can be switched off while still guaranteeing link functionality. The instant low power mode has the benefit of reducing the power consumption of the SFP transceiver so that, for example, host platforms with lower power delivery budgets can support the SFP transceiver for at least some applications.
摘要翻译：提供了一种降低小型可插拔（SFP）收发器的总功耗的方法。该方法包括以低功率模式接收操作SFP收发器的指示，并且响应于至少关闭控制温度的热电冷却器（TEC）的指示，将SFP收发器设置为低功率模式激光二极管的SFP收发器。每当达到不超过预定距离，例如65公里时，可以实现所提出的方法。在这样缩短距离的情况下，SFP收发器的TEC可以关闭，同时仍保证链路功能。即时低功耗模式有利于降低SFP收发器的功耗，例如，具有较低功率传输预算的主机平台可支持至少一些应用的SFP收发器。

摘要： An apparatus is provided comprising a small form factor pluggable module having an optical connector configured to be coupled to a plurality of transmit and receive single mode optical fibers and an optical transmitter comprising a plurality of uncooled laser diodes configured to transmit optical signals to a plurality of transmit single mode optical fibers via the optical connector. The small form factor pluggable module is a quad small form factor pluggable plus (QSFP+) 40GBASE-SR4 module that has been converted for use with single mode fibers by substituting their vertical-cavity surface emitting laser diodes (VCSEL) with longer range uncooled laser diodes. Example replacement lasers may include uncooled Fabry-Perot (FP) laser diodes or Distributed Feedback (DFB) laser diodes. To connect the module to lower grade fibers, a single mode-to-multimode mode conditioning patch cord is provided with a plurality of inline physical offsets, one for each pair of fibers.

摘要： Methods and apparatus for supporting a plurality of modulation formats using a single transmitter are disclosed. According to one aspect of the present invention, a transmitter arrangement that provides a signal to a modulator that creates an optical data stream from the signal includes an encoder and a switching/filtering arrangement. The encoder has a state that is varied between first and second encoder states. If the state is the first encoder state, the encoder encodes the signal in a format associated with an optical duobinary (ODB) modulation format. Otherwise, the encoder does not encode the signal in the format associated with the ODB modulation format. The switching/filtering arrangement receives the signal from the encoder, and provides the signal to the modulator. If the variable state of the encoder is the first encoder state, the switching/filtering arrangement has a low bandpass configuration. Otherwise, the switching/filtering arrangement has a high bandpass configuration.

摘要： A link probe for multimode fibers in optical networks is provided. An optical test probe signal is sent over a multimode fiber of an optical network link and a receiver converts the optical signal into an electronic signal with a trigger generated by the clock recovery section of an EDC (electronic dispersion compensation) unit. The digital signal is processed by a modified IEEE algorithm to determine a TWDP (Transmitter and Waveform Dispersion Penalty) parameter which quantifies the transmission quality of the multimode fiber and link suitability to LRM transmission.
