CDC MC Optical-4 Bridge

  • Overview

    The CDC MC Optical-4, a 1U rack mounted bridge, allows MegaCOMMS runs of 128 channels of 24-bit 96 kHz audio up to a distance of 2 km (6,561 feet) from bridge to bridge.

    The CDC MC Optical-4 has 4 pairs of MegaCOMMS ports (Tx, Rx) with a duplex optical LC port per pair allowing up to 512 channels of audio to be transmitted. Each of the four MegaCOMMS pairs are independent of each other allowing for complete flexibility to suite any application. The unit is also fitted with redundant PSUs as standard for peace of mind.

    Feature Summary

    • 512 channels can be sent up to 2 km (6,561 feet)
    • 0.011 millisecond of latency over 2 km
    • 4 pairs of MegaCOMMS ports (Tx, Rx)
    • 4 duplex multi-mode or single mode SFP LC optical ports
    • MegaCOMMS network ports glow either red or blue for Rx (receive) or Tx (transmit)
    • Dual PSUs as standard

    Cadac’s MegaCOMMS digital network allows the audio infrastructure to be designed to meet the requirements of the most challenging applications. With a choice of local I/O cards, stageboxes and audio network bridges plus a dedicated router to handle the dynamic management of the audio, the network can be as complex or as simple as required. 

    All Cadac digital audio is transmitted using Cadac’s proprietary MegaCOMMS digital interconnect protocol which provides less than 0.4 ms latency from analogue input on stage, through the CDC eight or CDC six, to analogue output on stage, plus robust error correction and advanced system clocking.

    The protocol provides up to 128 bi-directional channels of 96 kHz / 24-bit audio along with all control data and clock synchronisation. This is all carried on coaxial cable with runs of up to 150 meters (492 feet) from the console or MC Router. The benefit of combining audio, control, and clock into one single network simplifies connectivity, shortens set-up time and reduces investment in cabling infrastructure.
