Specifications and Regulatory Information
Specifications
tween normalization and insertion of the DUT
• amplitude stability of the system
• scale fidelity
If the DUT and associated cables are polarization maintaining, temperature is
tightly controlled, and the DUT is inserted without removing connectors, the
amplitude accuracy should be the same as the amplitude stability value.
Angled Connector Specifications
Wavelength and amplitude accuracy specifications require an angled connec-
tor from the source output to the normalized receiver input ports.
Angled contact connectors help you to control return loss. With angled fiber
endfaces, reflected light tends to reflect into the cladding, reducing the
amount of light that reflects back to the source.
N O T E
If the contact connector on your TLS is angled, you can only use cables with
angled connectors with your TLS. The receiver input has flat connectors and
the TLS output has angled connects. Do not connect an angled patch cord to
the flat receiver input connector or a flat patch cord to the angled TLS
connector output.
The angled connector symbol is typically colored green. You should connect
straight contact fiber end connectors with neutral sleeves to straight contact
connectors and connect angled contact fiber end connectors with green
sleeves to angled contact connectors.
