WDM-Wave Division Multiplexers- WDMs

Pluggable WDM



SFPs provide an extremely powerful, low cost and flexible WDM system. Since SFPs come in each CWDM wavelength, a full WDM system is easy to construct using the media converter or cross-connect systems for any protocol.


For Ethernet The technologically advanced Fiber DriverT WDM1616 Wave Division Multiplexer (WDM) from MRV Communications presents a cost-effective means for creating and managing high capacity fiber optic networks. Using a separate wavelength for each data channel, it multiplexes sixteen Gigabit speed, Full Duplex data channels over a single link of low water peak attenuation fiber (e.g. Corning? SMF-28eT). What would normally take sixteen pairs of fiber to transmit instead only takes one pair.

An affordable alternative to Dense Wave Division Multiplexers (DWDM), the WDM1616 is designed with Coarse Wave Division Multiplexing (CWDM) technology. With link distances of up to 35 km and support for Gigabit Ethernet, Fibre Channel, and FICON, the WDM1616 is an excellent solution for a wide variety of applications in Metro, Campus, and Government/Military environments.WDM, MRV provides a powerful eWDM solution, where SFP or GBIC optics with CWDM wavelengths plug directly into OptiSwitch modules designed for WDM use. This allows a truly simple-to-configure WDM system for sending large amounts of Ethernet data over a few fiber optic cables.

Overview
The Fiber Driver-LD series consists of multi-functional, compact and modular CWDM/DWDM systems specifically designed for metropolitan service providers and enterprises requiring a flexible, cost-effective system to multiplex, transport and switch high-speed data, storage, video and voice applications. The LD systems can create up to 64 independent virtual fiber links over a single pair of fibers over distances of up to 100km. The system supports different network topologies such as Point-to-Point, Star, Linear Optical Add/Drop Mux and Ring. Service providers and Enterprise customers deploy the LD systems to maximize the bandwidth and service flexibility of their networks.

The LD WDM systems use a modular architecture comprising three different chassis that are rack-mountable shelf:
LD1600 chassis can host 16 transponders plus OADMs, Muxes/Dmuxes, 1+1 redundancy, service and 2 management modules (for redundancy)
The LD800 chassis can host 11 transponders, OADMs, Mux/Dmux, 1+1 redundancy, service module and 1 management module
The LD400 chassis can host 5 transponders, OADMs, Mux/Dmux, 1+1 redundancy, service module and 1 management module

Modular System
High density form factor supports
- 1 to 16 CWDM channels
- 1 to 64 DWDM channels
- Hybrid CWDM and DWDM for transparent upgrade
The modules are hot swappable, allowing scalable, in-service expansion or channel maintenance
Multifunctional transponders provide transparent light paths compliant to ITU-T grid CWDM/DWDM wavelengths
A transponder module can be used in any LD family chassis
Rate independed: protocols of all data rates in the range of 10 Mbps to 2.7 Gbps are supported
Protocol transparent: Mix different protocols such as E3/DS3, SONET/SDH, Fast Ethernet, ESCON, Gigabit Ethernet, Fiber Channel, etc.
Multifunction, flexible SFP access transponders (TM-xSFP)
Special low dispersion solution for distances of up to 640 km.
Additional loop-back and power monitoring functionalities and other diagnosis information
