# Product Documentation
# Product Description

  DLMD-12I is part of our Industrial Passive xWDM filter series and supports 12 Channel interconnection over double fiber using LWDM (LAN-WDM) 1269.23-1318.35nm wavelength. DLMD-12I unit is for harsh outdoor environments supporting IP65 water, dust resistance, -40 to 85C industrial temperature, telecom pole or wall installation options and comes with ODVA double LC connectors for easy fiber connection. Unit is small in size, light in weight, is simple to install, requires zero configuration or maintenance and is fully passive – no power supply or cooling required. DLMD-12I is deployed in the far end site and used together in a scenario with DHMD-21 which is deployed in the main site and Industrial DCMD-9I deployed in the middle site. DLMD-12I connects to DHMD-21 through the DC¬MD-9I upgrade port. DLMD-12I uses TFF (thin-film filters) with added band skip filters and provides ≤3 dB insertion loss.

    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 DLMD-12I 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.
