 The EM2009-EM4 ESCON Multiplexer is a module for the Fiber 
Driver-LD CWDM/DWDM Solution. By multiplexing multiple channels via TDM into 
DWDM or CWDM the number of ports in a single fiber can be multiplied by a factor 
of TDM implementation, thus increasing the efficiency of fiber use as well as 
saving precious physical space. The first TDM product in Lambda Driver series is 
4x ESCON multiplexer module. The ultra compact design is ideally suited for 
ESCON applications, which often require many parallel links. A combination of 
the 4x ESCON Mux in the LD800/1600 chassis achieves extremely high levels of 
density - 128 ESCON services can be run over one fiber pair (with 32 
wavelengths). The electrically based multiplexing allows for a significant cost 
reduction and higher fiber utilization when compared to a pure optical 
multiplexing solution. The ESCON Mux link fiber interface can be 850nm/1310nm or 
CWDM grid for direct connection to the CWDM Mux.
