DWDM Filters

A range of products is available to deliver various types of DWDM filter functionality. Filters for 1, 2, 4, 8, 13, 40, and 80 channels (wavelengths) are available.

“MUX, DMX complementary pair” 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. OMS versions exist that include an Express/Expansion port to pass and continue all other wavelengths.

Terminal MUX, DMX products multiplex and demultiplex a full set of channels aggregated on a common line, with capacity ranging from 40 to 80 channels per unit. These are implemented in enclosed mounting shelves. Single line single circuit units (MDX-4000 and MDX-5000) support a choice of either 20 channels bi-directionally (MUX and DMX), or 40 channels unidirectionally (all MUX, or all DMX). All other versions are dual-line dual circuit modules, supporting simultaneously all channels MUX and all channels DMX.

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.

Band OADMs are dual-common fiber modules that drop a composite of several channels per port and add a composite of the same channels from the add port. In all cases, channels that are not dropped or added are expressed through.

Features:

DWDM, MUX, DMX Complimentary Pair – LGX

• 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.
• Enclosed Mounting Shelves
  Passive shelves are available for high-fanout power splitter application, and high-fanout DWDM MUX/DMX application. The shelves are enclosed metal units that mount in standard 19-inch and 23-inch racks. They have faceplate connectors for front access. Units are available in 1RU and 2RU height.

DZS offers an extensive suite of passive networking products with the functionality required to serve optical transport requirements. DWDM solutions ranging from 1 to 80 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.
