Figure 1: D-422-MG Block diagram
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. The D-422-MG module is supplied
together with the D-422-MG-C1 connector module. The optical output is made with a Fabry-
Perot laser diode for 1310±40nm or a DFB laser for 1550±40nm and the CWDM wavelengths
according to ITU-T G.694 from 1470±6nm up to 1610±6nm.
