Systems in the 310B series provide reliable voice-grade transmission of audio signals in most applications.
Incorporating AGC circuitry, the system does not require field adjustment. A unique two-color LED at the
transmitter end indicates input audio level and clipping. The basic characteristics of fiber — no hum or
pick-up, no interference from electromagnetic fields or radio frequencies, and no possibility of ground
loop interference since fiber is not an electrical conductor — ensure that the quality requirements of
intercoms, paging, and public address systems are met.
