Colorlight OP1 Ethernet-to-fiber transceiver
The Colorlight OP1 converts Ethernet twisted-pair signals to optical Ethernet. Its SC single-mode fiber connection is specified for a 10 km transmission distance, with a 10/100/1000Base-T RJ45 port for copper Ethernet. The device uses DC 5 V power and provides indicators for link status, data activity, speed, duplex mode and power.

Link setup and status checks
Match the SC optical connection, fiber type and link partner before installation. The specification identifies single-mode fiber; it does not provide a wavelength or a complete matching-pair configuration, so confirm those details for the intended link.
The Link/Act indicators distinguish a connected port from active data transfer: steady light means the link is connected, flashing means data is being exchanged, and off means the port is not connected normally. Use the rear DIP switches only after confirming the required link speed and fault-alarm behavior.
Frequently asked questions
What fiber connector does the Colorlight OP1 use?
The OP1 V1.1 specification identifies an SC optical connector and single-mode fiber. Confirm the matching optical link partner before installation.
What transmission distance is specified for the OP1?
The listed single-mode fiber distance is 10 km. The recommended CAT5e copper Ethernet distance is up to 100 m.
Which Ethernet speeds does the OP1 support?
The RJ45 port is specified as 10/100/1000Base-T. The optical interface is listed as 1000Base-X, and DIP switches provide forced 100 Mbps modes for the optical and Ethernet ports.
What power supply does the OP1 need?
The specification lists DC 5 V, 1 A, with device power consumption no greater than 1.6 W.
What do the OP1 rear DIP switches control?
They enable or disable link-fault alarm, storm suppression, forced 100 Mbps optical operation and forced 100 Mbps Ethernet operation. Match the settings to the link configuration.
