DataLink RS232C (OPT120K-SYNC) long distance optical converter

Manufacturer: DataLink
Model: OPT120K-SYNC

Features

  • OPT120K-SYNC is an optical synchronous modem that extends the distance between synchronous devices up to 120 km using single-core optical fiber.
  • Enables two-way communication while reducing cost.
  • Features a noise-resistant metal shell with a grounding point.
  • Equipped with a high-performance optical transmitter and sensitive receiver for stable, long-distance communication.
  • Immune to lightning and external noise, reducing the risk of equipment damage.
  • Plug-and-play operation—no configuration needed; just connect and power on.
  • Offers flexible mounting with DIN rail bracket or direct screw-mount.
  • Utilizes a single-mode SC connector for optical fiber connection.

Specifications

RS232C long distance optical converter
  • RS232C optical converters are used in pairs.
  • RS232C can be extended up to 120 km by optical conversion (single core).
  • It communicates bidirectionally between start-stop synchronous devices and synchronous devices via optical fiber.
  • No settings are required for communication.

Connection configuration

Through optical conversion, the communication distance between two synchronous devices can be extended by 120kM.
