Ciena 134-0005-950 Multiwave/Metro/CoreDirector/CN4200 DWDM transmission Optical Transmission Module

The Ciena 134-0005-950 is a Timing Module for Ciena’s DWDM optical transmission systems (the MultiWave/Metro/CoreDirector/CN4200 product families). A timing module distributes the reference clock and synchronisation signal across a shelf’s line and tributary cards, keeping every wavelength channel aligned to the same timing source so multiplexed traffic stays synchronised end to end. Failed or drifting timing hardware is one of the more disruptive faults on a DWDM shelf, since every card sharing that reference is affected rather than just one channel. This unit is supplied as a spare for engineers maintaining, expanding or restoring redundancy on an existing Ciena optical installation. Confirm the exact shelf and chassis variant against your platform before ordering, since the 134-prefixed common-equipment range spans several Ciena optical generations.
