摘要： An optical signaling header technique applicable to optical networks wherein packet routing information is embedded in the same channel or wavelength as the data payload so that both the header and data payload propagate through network elements with the same path and the associated delays. The header routing information has sufficiently different characteristics from the data payload so that the signaling header can be detected without being affected by the data payload, and that the signaling header can also be removed without affecting the data payload. The signal routing technique can overlaid onto the conventional network elements in a modular manner using two types of applique modules. The first type effects header encoding and decoding at the entry and exit points of the data payload into and out of the network; the second type effects header detection at each of the network elements.

摘要： A flexible optical harness containing lasers and photodetectors that are pre-aligned to light conduits may be provided. Light may be transmitted through an optical conduit comprising a core region surrounded by a cladding region. The coupling between optical conduits and emitting laser and receiving photodetector occurs via an interface between each designated optical conduit and between each photodetector and each designated optical conduit. A detector's active area forms an interface with the designated light conduit's core. The laser's emission area forms an interface with the designated light conduit's core. The said optical harness may, in addition, be combined with a flexible conducting harness between common blocks.
