6925 CWDM The Emcore Model 6925 Coarse Wave Division Multiplexing (CWDM) is an all-fiber, bidirectional multiplexor / demultiplexor. The CWDM allows up to eight, channels to be stacked in the 1550 nm regions of optical fiber for both unidirectional and bidirectional applications. The Model 6925 implements high channel-to-channel isolation to ensure that no interference occurs between channels in a bidirectional configuration. CWDM technology increases the capacity of embedded fibers, allowing system growth without costly cable plant upgrades. The Model 6925 is an excellent choice for addressing the increased need for efficient and capable signal transmission.
