305.0. "Certification Testers ??" by PEACHS::SCHULTZ (Peripheral Visionary...) Fri Jul 19 1991 16:09

    
    I've looked through this file and did not find this information
    available.
    
    What test equipment is required for the certification/repair of the
    62.5/125 MM Dual Window Fiber. I just finished watching the 3 DVN
    broadcasts, and they mentioned a tester that has been qualified for
    internal Field Service, but did NOT give a part number or cost. We will
    be installing a small FDDI network here in the Atlanta/CSC and I need
    to know what testers the wiring contractor should use for the
    certification process. I also plan on purchasing this tester so that we
    can do some of our own splicing/connectorization/troubleshooting of the
    Fiber runs in the future.

    Give me a call.  Here in the Atlanta Area, SSR NWSS contractors on BOA 
    all are required to have that equipment in hand when doing for for us. 
    Just step downstairs and ask someone in NWSS about it.  We have a set
    of the required test equipment in stock, if your sub doesn't.

305.2Part #'s & costs for testers BAGELS::LEVYMon Jul 22 1991 13:4814
     Dual Window Optical Loss Test Set, FC-10138-AC, ~$2800

     Used for accurately measuring attenuation of fiber cables at both
     windows. Required for cableplant certification. Also provides
     functionality of Optical Powermeter Kit (described below), with
     addition of a BN24D-01 cable.

     Optical Powermeter Kit, 29-28384-01, ~$500 

     Used on FDDI devices and the cableplant to isolate link problems.
     Strongly recommended for the SDU/branch DSE.

                                                
    
305.3Fibre TestingOTOOA::FELDBRUEGGETue Jul 23 1991 17:1325
    Hi!
    
    I've just returned from an internal fibre optics training seminar that
    was put on by the Photonics group in Kanata Canada. A major part of the
    seminar was about fibre optic attenuation and testing. This section of
    the course was delivered by the individual who is writting the fibre
    optic test procedures (installed fibre cables) for EIA.
    
    There is more to measuring fibre attenuation than putting a power meter
    on the cable and reading the numbers. An example - a correction factor
    for the difference in the operating wavelength of the LED light source
    of the power metre and the worst case wavelength (in the FDDI spec) of
    the FDDI products LED.
    
    OTDR's should not be used for measuring fibre attenuation (unless the
    FDDI hardware will use a LASER source). They can be off by as much as 
    3dB.
    
    The DECconnect Fibre Optic Installation manual section 7 contains a
    very good fibre test procedure. This section was written by the same
    organization that gave the seminar that I attended.
