Optocore provides a synchronous and redundant transport solution for video, audio and data over optical fibre.
Functioning as a redundant ring network, the Optocore optical fibre-based network system allows nodes to place and retrieve video, audio and data onto a 2GB network with an ultra low latency of 41.6 microseconds anywhere on the network.
Channels available on the Optocore network system include 768 audio channels, 32 serial data channels (32 universes of DMX), 1 video channel, and the option of either 2 additional video channels or 100Mbps Ethernet.
The channels can also be mixed and matched to suit the amount of data required in each format by a simple firmware change.
While this flexibility and data capabilities come with a price tag, the high convenience factor from the large distributed network of multiple formats makes the price tag pale in significance.
Optocore has however introduced a cost-effective version utilising a redundant ring topology on Cat5 called SANE (Synchronous Audio Network plus Ethernet). SANE essentially works the same way as the Optocore fibre optic network system with the same network latency, but limits the amount of channels that can be accessed from the network.
The SANE network system offers 64 audio channels and 100Mbps Ethernet, which can be used to distribute a DMX over IP stream out to moving lights and dimmers in multiple locations around the network by simply dropping a node in the required area.
One of the best features of the Optocore products is that nodes can be used to bridge the fibre Optocore network with the SANE network. This allows the nodes on each network to essentially share the available I/O from either network between the nodes up to the maximum channel and node count of each of the networks.
Optocore’s open protocol has encouraged various manufacturers including Studer, Soundcraft, SSL, Digico and AVID to come on-board to develop nodes, which not only allow control of their own stage boxes but also the high quality preamps available in the Optocore nodes.
These nodes use the most commonly used audio transport protocol across the manufacturers’ MADI to provide both audio and control information to be sent and received from the consoles to their respective stage boxes and the Optocore preamps.
Two devices have been designed for this application:
- DD2FR-FX, providing 128 x 128 MADI channels on two duplex fibre links
- DD4MR-FX, providing 128 MADI inputs and 128 MADI outputs on four coaxial links
Both nodes provide SANE and Optocore for connection to either network. The DD32R-FX builds itself on the DD32E to provide 32 configurable AES channel (64 audio channels in all) with both Optocore and SANE network ports.
The newly available Optocore AD/DA models, the X6R and the V3R are designed to be used with either the DD32R-FX or as a standalone break into the Optocore/SANE network for those units with available ports.
Available in 16-channel (X6R) or 8-channel (V3R) options, the X6R and V3R AD/DA units offer sample rates up to 192KHz and 0dB to +70dB gain in true 1dB steps, providing an effective range of I/O for the audio network.
The Optocore network also includes the V3R-FX and X6R-FX intercoms, a new line of 4-port and 8-port intercom converter units designed for use with Clear-Com Matrix systems. These units also feature 2 x Ethernet ports that allow full-duplex communication and control data between Clear-Com panels and Eclipse matrix frames to help maximise communications systems drops around large productions.
