    The 10Gtek’s WDM series comprises a set of CWDM passive modules mechanically compatible with the 10Gtek’s CWDM chassis (part number CWDM-CHASSIS-2=) and a 1300/1550 nm splitter cable. Compared to the previous 1000BASE-CWDM series of passive filters, this new set of devices sports a greatly reduced insertion loss (up to 50 percent), "power-tap" ports to allow live monitoring and troubleshooting of the CWDM signals, as well as the mixing of 1300-nm CWDM signals on the same fiber infrastructures.

    10Gtek’s CWDM solution applications:The 10Gtek’s CWDM solution based on CWDM gigabit interface converters (GBICs) and Small Form-Factor Pluggables (SFPs) and passive modules allows enterprise companies and service providers to provide scalable and easy-to-deploy Gigabit Ethernet and Fibre Channel services in their networks. The product set helps enable the flexible design of highly available and scalable multiservice networks.
    The 10Gtek’s CWDM GBIC SFP solution is a convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fibre Channel in campus, data-center, and metropolitan-area access networks.
    Because of the flexibility of the passive devices, 10Gtek’s CWDM solution helps enable the deployment of a variety of topologies to multiplex up to eight different wavelengths on the same pair of fibers in protected or unprotected configurations. A connection between two endpoints is protected when it is associated with two channels (typically of the same wavelength) traveling on diverse fiber routes (for example, clockwise and counterclockwise in ring configurations or on separate fibers in point-to-point scenarios). Single-wavelength OADMs are equipped with two channels traveling different network paths (east and west) to offer redundancy or protection in rings. On the other hand, because CWDM-MUX8A= and CWDM-OADM4-x= have only a single network port (that is, one fiber path), two CWDM-MUX8A= or two CWDM-MUX4-x= are required to connect to redundant (protected) fiber routes.
    Figures 1 through 10 illustrate the numerous protected and unprotected deployment scenarios of the Cisco CWDM solution with the Cisco WDM series of passive devices. The following conventions are adopted in the figures:

    • Colored circles represent transceivers (GBIC or SFP) at the corresponding color-coded wavelength connected to the filter equipment port.

    • N indicates the network port on the CWDM-MUX8A= and CWDM-OADM4-x=.

    • P indicates the pass port on the part number CWDM-OADM4-x=.

    • E and W indicate the network east and network west ports on the WDM-OADM1-xxxx=.
