摘要： In a WDM optical network DML signals are sideband filtered to compensate for chirp with a feedback loop carrying signals from a monitor unit which helps maintain the sideband filter offset from a peak output of the DMLs. Network components with filtering characteristics, such as AWGs, can be used as the sideband filters. The monitor units monitor the Q-factors or BERs of the filtered signals and the sideband offset is maintained by temperature control of the sideband filters with respect to the DMLs.

摘要： A method, an apparatus and a system for gigabit Ethernet (GbE) using only 2 pairs of wires for a single communications link are described. This network communication may be referred to as 2-pair 1000Base-T. GbE using only 2 wire pairs per link may offer increased port density over a conventional 1000Base-T link. As an alternative, 2-pair 1000Base-T may also provide increased link bandwidth over the existing 1000Base-T standard. When a given number of conventional links in a system are replaced by the same number of 2-pair 1000Base-T links, the system bandwidth may also be consequently increased. Transformers and power supplies may be combined with GbE utilizing only two wire pairs to provide power over Ethernet (PoE) solutions.

摘要： Optical transceiver modules with multiple channel connection with connectors on a motherboard of a line card for network devices, such as a switch, router, crossconnect and the like, are presented. The modules have staggered electronic boards which can engage the connectors which are laterally displaced on the motherboard. The connectors are also arranged so that one of them can engage an optical transceiver module in an SFP connection so that the motherboard connectors are compatible with multiple channel and single channel (SFP) connections.

摘要： Techniques for multiple channel optical transceivers for use in network devices are provided. In general, a row of optical emitters are disposed adjacent to a row of optical detectors in order to provide increased bandwidth and reduced optical crosstalk. Each row can be electrically coupled to an associated transmitting electronic board or detecting electronic board to reduce electronic crosstalk. The configuration of the optical emitters and detectors allow enhanced flexibility in dressing out the optical fibers and routing them to other network devices.
