Datasheet

MRV Optical Communications Systems®

The RD-DMDXA40 enables separation of the

active equipment from wavelength multiplexing

components. It may be used in conjunction with

active optical devices from MRV (see Fiber Driver®,

Lambda Driver®, OptiSwitch™, CrossConnect™,

Packet Optical Transport product lines) or from any

other DWDM-compliant manufacturers.

The RD-DMDXA40 may be used as a standalone

tabletop device or mounted in 1-unit space of

a 19” data rack. Rack mounting options include

standard flush front mount or mid-chassis NEBS

level 3 configurations. The RD-DMDXA40 front panel

features dual LC (DLC) fiber connectors for the 40

DWDM channels as well as a DLC fiber port pair for

the multiplexed DWDM trunk link.

With front accessible connections and no need for

power, the unit may be fully operational in minutes

after unpacking the box.
