Abstract: A method, a system, and an apparatus provide for a cable modem termination system (CMTS). The CMTS may include a virtual machine configured to provide a plurality of virtual CMTSs (vCMTSs). The CMTS may also include a plurality of subscriber groups. Each subscriber group of the plurality of subscriber groups may be assigned to a vCMTS of the plurality of vCMTSs. Additionally, each vCMTS is configured to provide a process.

Abstract: 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.
