363.0. "Optical loss measurement on single mode fiber" by UTRTSC::DENIJS () Wed Oct 16 1991 13:17

I know there is a Dual Window Optical Loss test set (intelco) part nr
FC-10138-AC used for cable plant certification.

Is there a separate set required for Single mode fiber certification ?

If so, can somebody give a partnumber?

Thanks in advance,
Peter de Nijs.

INTELCO SDU Power Meter - 29-28384-01

INTELCO Multimode power loss test kit (includes power meter, light source, 
connectors, and cables - FC-10138-AC

INTELCO Singlemode power loss test kit (does not include power meter. Includes 
laser source, connectors, and launch cables) - 29-29033-01

FC-type adapter (used to adapt SM fiber to SDU meter)- 29-29036-01

Hope this helps,
Brad
363.2some clarifications to a good summaryBAGELS::LEVYWed Oct 16 1991 17:2716
    re: .1
    
    Minor nits:
    
    Only the multimode test kit is manufactured by Intelco. The SDU Power
    Meter is made by EXFO. The singlemode source kit is made by Fotec.
    
    The FC-type adapter is used with the power meter in the Intelco kit.
    
    To make single-mode loss measurements, you need all three pieces:
    
    1) Intelco power loss kit
    2) Fotec single-mode source kit
    3) FC-type adapter
    
    The SDU power meter shouldn't be used to certify optical cables.

Interesting, I was going by information provided to me from Ed. Services and the
course they are/or will be teaching on FDDI. In there material it states that 
everything is made by INTELCO. 

I take it the Multimode Intelco power loss kit includes the EXFO SDU power meter?
So, the SDU power meter should only be used for relative power loss measurements
on singlemode fiber as discribed in Appendix B on the DECconcentrator 500 
Single-mode Option Card Installation guide.

Is a OTDR the only acceptable method for certification for single-mode?

I'm I loss or all wet? Or should I just go home for the day?.....8*)
363.4what's used whenBAGELS::LEVYThu Oct 17 1991 12:1916
    I'll follow up with Ed Services to correct their course material.
    
    The Intelco kit has a dual window source and a temperature-stabilized 
    power meter that can make both relative & absolute power measurements.
    Both devices are made by Intelco. The kit costs a little under $3000.
    
    The SDU power meter is made by EXFO. It only does absolute power
    measurements, and is not temperature-stabilized. It costs about $500.
    
    To certify single-mode cables, you use the Intelco meter and a laser
    source, which is made by Fotec. The source kit costs about $700.
     
    The OTDR is used for certifying splices & intermediate connections, as
    well as measuring distance. It also establishes a baseline profile of
    the fiber. It shouldn't be used for making power loss measurements.
    It's used on both single-mode and multimode fibers.

Thanks for all the inputs and interrest.
