VoIP FTTx Carrier Ethernet Ethernet Demarcation Multi-Service Access Optical Transport Wavelength Multiplexing TDM NMS/EMS Network Optimization	Wavelength Multiplexing » Passive OADM Passive optical add/drop multiplexers (OADM) provide the ability to “drop and add” or “drop and pass” one or more of the wavelengths from the fiber locally. A Metrobility R4000 with an Optical Add/Drop Multiplexer (OADM) module or 4-channel multiplexer at the subscriber site provides the "drop and pass" or "drop and add" capabilities. Metrobility R4000 Managed Coarse Wave Division Multiplexing Sub-categories: Passive OADM Active CWDM

Metrobility’s Coarse Wave Division Multiplexing (CWDM) solution combines passive optical CWDM technology with Radiance Access Line Cards and Gigabit Ethernet line cards and superior network element management through NetBeacon® Element Manager to achieve maximum flexibility, scalability, and manageability. This combination creates a robust and flexible managed point-to-point or ring network solution. Metrobility’s CWDM solution is ideal for applications where dedicated bandwidth, enhanced diagnostics, and a secure PON connection are required on a single fiber pair.
The CWDM network provides a cost-effective “no new fiber upgrade” solution for adding a new services and customers to an existing fiber infrastructure.
