This Service Delivery Point (SDP) unit is a 1RU sliding drawer, short depth module (e.g. 155mm deep body) and provides patching facilities only in an optical fibre equipment or termination rack. The SDP unit may also be used as a coupler tray, holding two couplers; either WDM or Monitoring/Interception types. It may be front, middle or rear mounted, in a 19” or 21” rack, and has an interchangeable, 12 position flat patch panel at the front face. The screw secured drawer only opens 95mm. A wide tray is provided at the front of the SDP unit, for guiding outgoing (Customer) patch cords. Fusion splicing is performed elsewhere. Various modules are available to suit different connector types. E.g. Part No’s: TC27102SC12S (SC through connector); TC27102ST12S (ST through connector); TC27102FC12S (FCPC through connector); etc. The unit has a universal rear entry for a 22mm ID/25 mm OD, flexible convoluted tube (e.g. Part No: TC1279-54), which allows entry from either side. This tube is available separately.
