DWDM
Passive Components
The Emcore Model 2925 Dense Wave Division Multiplexing
(DWDM) is an all fiber bidirectional multiplexor / demul-
tiplexor. The DWDM allows four, eight, 12, 16, 24 or 32
channels to be stacked in the 1550 nm regions of optical
fiber for both unidirectional and bidirectional applications.
The Model 2925 implements high channel-to-channel
isolation to ensure that no interference occurs between
channels in a bidirectional configuration.
DWDM technology increases the capacity of embedded fibers, allowing system
growth without costly cable plant upgrades. The Model 2925 is an excellent
choice for addressing the increased need for efficient and capable signal
transmission.
