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.
