Overview
The 346A Interface System provides superior and reliable
transmission of analog signals in the most demanding applications.
A standard series 346A system consists of two electrical
transceivers for single-fiber operation at 850/1300 nm. A dualfiber version for 850 nm or 1300 nm may also be specified.
Maintains System Audio Quality
Incorporating optical AGC circuitry, the system does not require
field adjustments either during or after installation. Distortion
is kept very low throughout the system, enabling the quality
requirements of intercom, paging, and music systems to be met.
Superior Diagnostics
The SMARTS™ diagnostic technology provides LEDs that
monitor the operating status of the optical signal.
