70 -- 11 FIBER OPTIC SWITCH BOXES SOL N00178-99-R-2012 POC James McCaffery, Code SD12D, (540)653-7942 WEB: NSWCDD Procurement Homepage, http://www.nswc.navy.mil/supply. E-MAIL: Questions concerning synopsis., mccafferyjg@nswc.navy.mil. DESC: The U.S. Navy/NSWCDD intends to negotiate on a sole source basis an indefinite quantity delivery order (firm fixed price) contract for acquisition of up to twenty-seven (27) each fiber optic switch boxes, from Litton network Access Systems Inc., P.O. Box 11966, Roanoke, VA 24022-1966. This device is a fiber optic switchbox containing fiber optic splices, repeaters, fibers, optical bypass switches and power supplies. The switchbox is for naval shipboard implementation of fiber optic token ring LANs. Optical bypass switches are used as Trunk Coupling Units (TCUs) and Switchbox Bypass Units (SBUs). Each switchbox enables remote nodes on the LAN to connect (via the TCUs) to either or secondary trunk cables (IAW NAVSEA DWG 6710785) The switchbox shall support up to two rings with separate power supplies for each ring. Repeaters are incorporated into the switchbox to ensure that signal power levels do not degrade below required levels along the LAN. Power for the repeaters is derived from the ship's power source and converted to appropriate levels inside the switchbox by internal power supplies (one supply per repeater). The power supplies also enable the SBUs. The SBU allows signals to the TCUs and the repeater only when power is available to the switchbox; otherwise the SBU bypasses the TCUs and the repeater. The TCUs route optical signals according to commands received along the electronic interface cable (EIC) (See NAVSEA DWG 6710785). When enabled, the TCUs route the optical signal to the remote node; when disabled, the signal bypasses the node, thereby eliminating the node from the LAN. This normally occurs when the node is powered off, but it can also act to isolate faults on the LAN by disengaging faulty or damaged nodes. Fiber optic splices are the only method of interconnecting fiber optic cables with elements used in the switchbox to minimize signal attenuation in the LAN. Cables shall enter the switchbox via Multi-Cable Transits (MCTs). Internal fiber pigtails shall be optical fiber cable components (OFCCs). See NAVSEA 6710782 and MIL-C-85045/16. This item is being purchased to support emergent switching requirements of the Aegis Combat Systems Center of the Naval Surface Warfare Center Dahlgren Division, Dahlgren, Virginia. Note 22 applies. All responsible sources may submit a proposal, which shall be considered. Solicitations and amendments will only be available via the World Wide Web at http://www.nswc.navy.mil/supply. No hard copies will be provided. Vendors should access the NSWCDD web site to ensure they have downloaded all amendments. For solicitations issued after 31 May 1998, DOD will no longer award contracts to contractors that are not registered in the Center Contractor Registration (CCR) database. Registration may be done by accessing the CCR Web site at http:www.acq.osd.mil/ec or via dial up modem at (614) 692-6788, (USER ID: ccrpub; PASSWORD pub2ccri). Any certified value added network (VAN) can be used for registration. A paper registration form may be obtained from the DoD Electronic Commerce Information Center at 1-800-334-3414.
