Connector Type
The high-density LC Duplex connector has a tabbed
locking mechanism similar to what you would find on a phone
jack. This enables secure connectivity and easy removal.
The SC (subscription channel) Duplex connector is a low
insertion loss connector using a push/pull locking mechanism.
Optical Fiber Cable
The SC-LC optical fiber cable required in this application
is a multimode duplex fiber optic patch cable with a core/clad
-
ding size 62.5/125 micron suitable for low-to-moderate-speed
data links (≤100Mbps). The following Fiber Instrument Sales,
Inc. part number X2YLM3FISC may be used to reference
the physical characteristics of the required cable assembly.
The full-duplex nature of the audio network interface requires
one fiber for transmit, and one for receive; hence dual zip cables are recommended.
Optical fiber cables are manufactured with a variety of jacket materials, which
directly affect cable cost, including Thermoplastic Elastomer (TPE), Kynar® and
Teflon® FEP. Physical properties of the jacket material determine a cable’s resistance
to abrasions, flame retardancy, etc.
Check local codes to be sure the cable you plan
on using is compliant in your application.

digitally controlled gain, up to a maximum of 70 dB, and displays remarkably high
performance and accuracy. Phantom power is available.
