| MRV's eWDM systems provide a simple, efficient, flexible and cost effective solution for deploying Gigabit Ethernet services in Campus, Metropolitan area access networks, highways, the transportation industry and Cable TV - MSOs. The Ethernet WDM (eWDM) solution's building blocks are: - OptiSwitch WDM - pluggable module with WDM SFP - LDP300 - All Optics Chassis (passive) - CWDM Optical Add-Drop Multiplexers (OADMs) • Easy Deployment and flexible implementation: - Passive Optical Solution - No-power required - No configuration needed - Can work with standard LD family OADM/MUX modules - Interfaces directly to WDM (SFP/GBIC) pluggable optics • High availability and redundancy protection: - OADM: O-BPSR and O-UPSR for system and fiber cut protection - OptiSwitch GER module for fiber signal redundancy - Protocol (RSTP MPLS) redundancy • Investment protection - Enables enterprises and service providers to increase the bandwidth of existing GE optical infrastructure without adding new fibers |
