OTDR: Launch Cable; Receive Cable

[rjhintz]

I'm familiar with the use of a launch cable with an OTDR, but, in
reviewing the JDSU Fiber Test Reference Guide, http://lw.pennnet.com/whitepapers/wp.cfm?id=665,
discusses the use of a receive cable as well.

How important is a receive cable?

[Michael Stalnaker]

The receive cable allows the OTDR test to pass through the far end
connection. If the validity of the far end connection is needed then a
receive cable helps provide an accurate assessment.

The receive cable is required to make accurate and complete OTDR
characterizations in an optical path link.

The need for a receive cable makes sense, in the same way that using a
launch cable makes sense. The logistics of getting the receive cable
at the end point are complex (this is an inter-city singlemode shot,
so I was trying to avoid it). Thanks, though.
