## Overview

The SML Series CWDM Passive mux/demux Module offers a cutting-edge solution for expanding your fiber network with 8+1 duplex channels, featuring a broad 1310nm channel. With exceptional insertion loss, superior channel isolation, and robust thermal stability, this module is designed for seamless integration and reliable performance in any professional setting.

## Description

Note: Only the card is sold under this part number. The chassis is sold separately. The core of a CWDM application is the passive MUX/DEMUX unit. The new CWDM mux/demuxes from SML-1000 series adopt a modular format. Each mux/demux can be used as standalone or can be installed as card in a simple SML-1000 chassis with 4 slots. An SML-1000-CH chassis can be installed in 19" rack and occupies only 1U of rack space. The SML-1000-MD81-47-LCU mux/demux bundles the main 8 CWDM channels: 1471, 1491, 1511, 1531, 1551, 1571, 1591 and 1611nm and also adds an additional broad channel for 1310nm. This allows the CWDM solution based on this mux/demux to be deployed over an already existing 1310nm connection with a minimum downtime and minimal changes.

## Features

- covers main 8 CWDM channels: 1471, 1491, 1511, 1531, 1551, 1571, 1591, 1611nm and the 1310nm channels (with broad 90nm opening), making it perfectly suitable for adding channels over existing 1310nm fiber connections
