The DN9680 provides a high channel count solution to the 100 metre limitation that Ethernet and CAT5 cabling imposes on the physical size of AES50 networks. A pair of DN9680 units allow up to eight AES50 connections (192 bidirectional channels) to be extended by up to 1,000 metres via single mode optical fibre or 100 metres via CAT5 copper cable, greatly simplifying long haul cable connections due to the use of a single bidirectional snake cable.
DN9680 acts as a bidirectional multiplexer and demultiplexer, and combines the eight incoming AES50 streams into the outgoing snake connection, and simultaneously also takes the incoming snake connection and unbundles the eight AES50 streams and routes them to the corresponding AES50 ports. A snake system consisting of a pair of DN9680 units routes the incoming AES50 streams to the outgoing streams on a one-to-one port basis, so that the snake is transparent in use, only incurring a small propagation delay of 250 microseconds.
As standard, DN9680 is compatible with single-mode dual fibre cable. As an option, the DN9680-MM upgrade kit allows conversion for use with multimode dual fibre cable over a 500 metre range.
