Multiple Topologies and Configurations
The Alcatel-Lucent 1692 MSE sup- ports point-to-point links and ring networks with coarse optical add/drop multiplexer (COADM) technology. The terminal can support up to 16 wavelengths of unidirectional transmission or 4 wavelengths of one fiber bidirectional transmission. The back-to-back terminal, which normally is used as the hub node in a ring network, can add/drop 16 wave- lengths. The COADM node can add/drop 1, 2 or 4 wavelengths for unidirectional application, while it adds/drops one channel for a one fiber bidirectional application. There are two types of CPE: one channel CPEs and two channel CPEs; this provides a cost-effective solution when the remote network node has only one channel.
Figure 2 shows a two fiber ring network.
With the Alcatel-Lucent 1692 MSE, data applications are easily implemented
and network expansions, based on end-user demand, are simplified. Easy to install, operate and maintain, the Alcatel-Lucent 1692 MSE allows enterprise and network operators to simplify their overall deployment process, directly improving both CAPEX and OPEX. No amplification is required for short-haul applications; however if longer reaches are required, electrical regeneration can be provided for distances greater than 80 km.
With temperature-hardened compo- nents, the Alcatel-Lucent 1692 MSE can be installed in virtually any network environment, from a basement closet to a central office.
The Alcatel-Lucent 1692 MSE sup- ports the following network topologies:
•Ring networks
•Point-to-point links
•CPE configuration in point-to- point links
•CPE configuration in ring networks
