摘要: An electro-optic transceiver module, method of manufacturing, and method of transmitting signals are provided that allow multiple optical signals at different wavelengths (e.g., according to CWDM) to be combined for transmission via a number of optical fibers that is smaller than the number of electrical channels according to which the optical signals were generated. Thus, CWDM may be used in connection with lower-cost VCSEL technology (e.g., as opposed to higher-cost edge-emitting lasers) by providing for wavelength compensation at the VCSEL driver to offset any changes in wavelength that may have otherwise occurred at the VCSELs. In particular, a microcontroller of the electro-optic transceiver module correlates a monitored temperature of the VCSELs to an actual wavelength of the corresponding optical signals transmitted by the respective VCSELS and determined an adjustment in a current supplied by the VCSEL driver to each VCSEL to achieve more precise and consistent wavelengths at the VCSELs.

摘要: An apparatus and method of assembly are described that provide improved mechanisms for cooling an optoelectronic transducer in a fiber optic system. The apparatus includes a thermoelectric cooler (TEC) secured to the optoelectronic transducer for removing heat from the optoelectronic transducer in response to instructions from a TEC driver, as well as a microcontroller electrically connected to the TEC driver for monitoring temperature and communicating with the TEC driver to selectively activate and deactivate the TEC at least partially based on the monitored temperature and/or other measured/detected data to effect a more efficient cooling mechanism for optoelectronic transducers, such as VCSELs. In addition, the user may be able to configure the system to maintain the optoelectronic transducer within a user-defined range of temperatures. In this way, a longer life and better performance of the optoelectronic transducer may be achieved, and datacenter costs related to cooling and/or maintenance may be minimized.
