Communication Channels

The Cisco Metro 1500 series operates using the International Telecommunication Union (ITU) wavelength grid of 200-GHz channel spacing. It receives the signal from the local device and converts it to the desired wavelength. Only single-mode fibers (remote or trunk fibers) are used for multiplexed data transmission.

The Cisco Metro 1500 series system provides communication within a broad range of data rates, up to 2.488 Gbps, and within a guaranteed optical budget. The system is transparent to any data communication protocol except wavelength channel modules (WCMs) with clock recovery. For more details on data rates, optical budgets, and supported protocols, see Appendix A, “Specifications.”

The Cisco Metro 1500 series system also provides monitoring and service functions such as loss of light and bit-rate control, as well as local and remote loopback.

Communication Channels

DWDM technology allows different channels to be combined for transportation over one fiber pair. A pair of multiplexer (MUX) and demultiplexer (DMX) modules assemble the channels into four groups of up to eight channels. The band splitter module (BSM) assembles and disassembles the four groups for the two remote fibers.

The optional remote switch module (RSM) provides line protection to the system. If the working line fails, the RSM routes the combined service automatically to a backup line. If used, the RSM is installed only in the primary chassis.
