Optical Talk Set

Full-duplex fiber communication with an integrated stabilized light source

JW4103N optical talk set combines full-duplex digital voice communication and a stabilized optical light source in one handheld instrument. Designed for installation, optical testing, maintenance, and fiber attenuation testing, it is suitable for data networks, CATV networks, and telecommunications networks.

With a transmission distance of at least 100 km, this optical talk set supports communication over long fiber links while providing clear voice transmission with low background noise. When paired with an optional fiber-optic clip-on coupler, it can also support in-service communication without disconnecting the fiber link.
