CWDM Filters

A range of products is available to deliver various types of CWDM filter functionality. Filters for 1, 2, 4, 8, and 16 channels (wavelengths) are available.

“MUX and/or DMX bidirectional” modules implement a filter for a full set of channels on a single common fiber. They can be deployed unidirectionally (all ports multiplexing, or all ports demultiplexing) or bidirectionally (mixed, with some ports multiplexing and other ports demultiplexing). All modules include a separate 1310 nm overlay port.

“MUX or DMX complementary” modules are single-circuit single-fiber filters provided in matched pairs, one module for multiplexing, and its complement for demultiplexing. Insertion losses per channel are complimentary such that end-to-end MUX-to-DMX loss is the same for each channel on the fiber.

“MUX, DMX two-circuit combo” modules include a multiplexing circuit with its common fiber, and a separate demultiplexing circuit with its common fiber, packaged in one single-width module. Insertion losses per channel are complimentary such that end-to-end MUX-to-DMX loss is the same for each wavelength on the fiber.

OADM modules multiplex and demultiplex a subset of channels on the common line. They exist in dual-common fiber and single-common fiber versions. Dual-fiber OADMs package a drop (DMX) of channels from the line and separately package an add (MUX) of the same channels onto the line. Single-fiber OADMs have a single bidirectional common and express filter, permitting a wavelength to be either dropped or added uniquely on the line. In all cases, channels that are not dropped or added are expressed through.

Features:

  • LGX Modules
    LGX modules are packaged in the industry-standard format originally designed by Lucent Technologies. All are passive, with no power or ground, and have front access faceplate connectors. They are deployed in the Optelian family of CMS passive mounting shelves, or in any standard LGX-compatible passive mounting platform. For information on the CMS shelves, refer to the Spec Sheet. LGX modules for DWDM are available in single-slot and triple-slot widths.
  • DMS Modules
    DMS modules are packaged in a format similar to LGX but are more compact in height. All are completely passive with no power or ground, and have faceplate connectors for front access. DMS modules are designed to fit in the Optelian DMS-0104 passive mounting shelf. For detailed information on the Optelian DMS mounting solution, refer to the Spec Sheet. DMS modules for DWDM are available in single-slot and half-slot widths.
  • OMS Cards
    OMS format passive cards are designed to fit in the Optelian family of OMS active mounting shelves. They contain passive optical elements, and all optical signals are transported passively. The cards additionally have electronics to allow connectivity to the OMS shelf purely for system detection purposes. For information on the OMS shelves, refer to the Spec Sheet. All cards are single-slot width.
  • Splice Trays
    Optical devices are packaged in industry-standard outside plant (OSP) splice tray modules, such as FOSC-B. Custom packaging options are also available. Splice tray modules are designed to be installed in any general OSP enclosure, such as cabinets or huts.

DZS offers an extensive suite of passive networking products with the functionality required to serve optical transport requirements. CWDM solutions ranging from 1 to 8 channels per unit are available in a variety of packages for deployment in many environments. Customer-specific versions are an option. Multiple options for MUX-only, DMX-only, combined MUX and DMX, and OADM ensure maximum flexibility and ideal fit.
