Techniques are disclosed for providing bi-directional data services involving a plurality of wavelengths. The data services may be hybrid in nature, including both digital and analog data signals. The techniques may be implemented, for instance, in an optical module, and allow one or more wavelengths to pass-through while other wavelengths are terminated or otherwise diverted. In one example embodiment, the techniques are embodied in a quad-port optical module having two input/output (I/O) ports and pass-through capability for at least one of the wavelengths, add capability for at least one wavelength, and drop capability for at least one wavelength. The module may further include transmit and/or receive capability for one or more signal types. The module can be operatively coupled with a bidi device or other suitable transceiver, to provide modular transmit-receive capability for a desired signal type.

A modular laser package system may be used to mount one type of laser package, such as a coaxial or TO (transistor outline) can laser package, to a circuit board, such as a transmitter board or a motherboard, designed to receive another type of laser package housing, such as a butterfly-type laser package housing. The modular laser package system may include a circuit board mounting platform, a laser housing mount to mount the laser package to the circuit board mounting platform, and a mounting base to facilitate mounting to the transmitter board or motherboard. The modular laser package system may also include a temperature control device, such as a thermoelectric cooler (TEC), and a temperature sensor, such as a thermistor, mounted to the laser housing mount to control and monitor the temperature of the laser package.
