Colorlight OP4 LED fiber optic transceiver
The Colorlight OP4 converts between optical and Ethernet data connections in an LED control system. It has two 2.5 Gb/s optical ports and four 1 Gb/s RJ45 ports. The V1.0 specification lists standard single-mode, dual-core LC optical modules with a transmission distance of 2 km.
Connections and installation
The OP4 supports automatic bidirectional optical/electrical conversion without driver installation or device configuration. It can be used in pairs or with a compatible master controller that provides optical output. Hot plugging is supported. All connectors are on the same side to simplify wiring behind or inside the LED screen.
Confirm optical rate, module type and controller compatibility before connecting a link. A controller having an optical port does not by itself establish compatibility with this 2.5 Gb/s transceiver.

Frequently asked questions
What optical data rate does the Colorlight OP4 support?
The OP4 specification lists two optical ports operating at 2.5 Gb/s. Its four RJ45 ports operate at 1 Gb/s each.
What fiber and connectors are specified for the OP4?
The specification recommends single-mode LC–LC fiber, 9/125 μm, with PC or UPC connectors. The listed optical modules use duplex LC connections at 1310 nm.
How far can the standard OP4 optical modules transmit?
The V1.0 specification lists a 2 km transmission distance for the standard single-mode modules.
Do I need two OP4 units for a link?
The OP4 can be used as a pair or with a compatible controller that already has optical output. Confirm the controller and optical interface compatibility before selecting the arrangement.
Does the OP4 need drivers or a separate configuration process?
The specification describes automatic bidirectional operation without drivers or device settings. The LED controller and screen still require the correct system configuration.
