Abstract:
Network devices, systems, and methods, including program instructions are disclosed which provide a converged fabric for Fiber Channel over Ethernet (FCoE). A network device includes a Fiber Channel Controller (FCC), located outside of a lossless Ethernet network. The FCC has a processing resource coupled to a memory. The memory includes program instructions executed by the processing resource to terminate Fiber Channel (FC) Initialization Protocol (FIP) frames, generated to and by initiator and target devices, on the FCC.
Abstract:
An optical connection infrastructure has optical conduits between first devices and at least one second device. Dynamic reconfiguration of the optical connection infrastructure can be performed from a first connection topology to a second, different connection topology based on programming of the first devices.

Abstract:
Optical transmitter apparatus 10 comprising a reflective optical amplifier 12, a driver 14, an optical splitter 16, polarisation compensation apparatus 18 and an optical router 20. The reflective optical amplifier is arranged to receive an optical seed signal. The driver is arranged to generate a drive signal arranged to cause the reflective optical amplifier to amplify the optical seed signal to form an optical signal. The optical splitter is arranged to receive the optical signal and to split off a part of the optical signal to form a further optical signal. The polarisation compensation apparatus is arranged to receive the further optical signal and to rotate a polarisation of the further optical signal by a pre-determined amount, to form a further optical seed signal. The optical router is arranged to receive the further optical seed signal and to direct the further optical seed signal to the reflective optical amplifier for amplification thereby.
Abstract:
An optical network unit is provided comprising a tunable laser, wherein the tunable laser is tunable such that a point-to-point connection to another optical network unit established via an optical fiber. Also, a method for processing data in an optical network and an according communication system are suggested. The tunable laser can be adjusted based on a detected collision, and a frequency grid can be supplied from a centralized component.
Abstract:
A fiber to copper patch terminal includes selectively activated circuitry for controlling an associated transceiver to produce a condition where normal communication with a connected power patch panel module has been temporarily interrupted. The patch terminal includes a selectively activated location identification function. This function when activated causes the optical transceiver to transmit a location signal preferably during a period where communication is awaiting resetting. In a preferred embodiment the patch terminal is designed to transmit the location signal during a period where Ethernet communication as awaiting completion of a reset.
Abstract:
Fiber optic cable assemblies (40) and fiber optic terminals (318-1,318-2) supporting port mapping for series connected fiber optic terminals are disclosed. In one embodiment, a fiber optic cable assembly (40) is provided. The fiber optic cable assembly (40) includes a fiber optic cable (41) having a plurality of optical fibers disposed therein between a first end (42) and a second end (43) of the fiber optic cable (41). The plurality of optical fibers on the first end (42) of the fiber optic cable (41) are provided according to a first mapping. The plurality of optical fibers on the second end (43) of the fiber optic cable (41) are provided according to a second mapping. In this regard, the fiber optic cable assembly (40) provides port mapping of optical fibers to allow multiple fiber optic terminals (318-1, 318-2) having the same internal fiber mapping to be connected in series in any order, while providing the same connectivity to each of the terminals (318-1, 318-2) in the series.
