The flashlink D-422-MG module provides an economical solution for transmitting RS-422 and GPI data signals via fiber optic cable. A pair of D-422-MG allows bi-directional transmission of up to 8 RS-422 and 16 GPI data lines for distances over 60km. When access to fiber is limited, D-422-MG can be combined with the flashlink optical multiplexing WDM, CWDM or DWDM products.The D-422-MG module multiplexes up to 8 RS-422 and 16 GPI inputs into an outgoing datastream while at the same time demultiplexing an incoming datastream into 8 RS-422 and 16 GPI outputs. The outgoing multiplexed stream is available both as an optical signal and as an electrical signal for use with a flashlink multichannel DWDM system.As stand alone unit, the D-422-MG module utilises 2 fiber strands for bi-directional data transport. Using either 2 fiber strands or optical multiplexing technology guarantees minimum possible latency for applications where timing is crucial.
