摘要： An optical transceiver that includes a modification that prevents interoperability with standard transceivers, while enabling them to work in the same slots and equipment as standard transceivers, provided that they are interoperating with a similarly modified transceiver on the other end of the optical link. Ideally, the polarity of the data in both the transmit and receive direction is inverted resulting in valid data for a link when a pair of modified modules are used and invalid data when a modified module is used with a standard fiber optic transceiver. The function is otherwise transparent to the host equipment.

摘要： A tunable semiconductor laser comprises a gain section having an MQW active region, a uniform pitch grating DFB region, and first waveguide. A composite reflector, including a second MQW region and a second waveguide, forms a cavity resonator with the DFB region. A voltage applied to the composite reflector induces a quantum confined stark effect, thereby allowing the wavelength to be altered. In one embodiment, the current drive to the active region and the shape of the first waveguide (e.g., a raised-sine function) are mutually adapted so that N longitudinal modes have essentially the same threshold gain and so that the DFB region spanned by the first waveguide is segmented into N zones, each zone providing optical feedback at a different wavelength corresponding to a different longitudinal mode.
