# Product Documentation
21 Channel 25G Ready Double Fiber Hybrid MUX/DEMUX Datasheet - DHMD-21
# Product Description

  DHMD-21 is part of our Industrial Passive xWDM filter series and sup¬ports 21 channel interconnection over double fiber using 9 CWDM channels, 1331-1371nm and 1471-1571nm wavelength from ITU-T G.694.2 grid and 12 LWDM (LAN-WDM) channels, 1269.23-1318.35nm wavelength. DHMD-21 is a 1U unit deployed in a standard 19-inch telecom sub rack, is simple to install, requires zero configuration or maintenance and is fully passive – no power supply or cooling required. DHMD-21 is deployed in the main site and used together with Industrial DCMD-9I deployed in the middle site and DLMD-12I which is deployed in the far end site. Both Industrial DCMD-9I, DLMD-12I are deployed in harsh outdoor environments. DHMD-21 uses Compact CWDM and LWDM TFF (thin-film filters) technology with band skip filters to achieve ≤4.0 dB insertion loss. Unit has a monitor port, which ensures easy troubleshooting without downtime.

    xWDM filters are data rate or line protocol neutral and are used in combination with colored optical transceivers which ensure desired application and data rate. Typical use case for DCMD-21 filters are 5G/4G Mobile Fronthaul Network Baseband Unit (BBU) and Remote Radio Head (RRH) interconnection (CPRI/eCPRI protocol), Enterprise Network 25G/10G Ethernet links or Datacenter 32/16/8G Fiber Channel connections.
