Fiber optic LC loopback adapter ACT EA9004 singlemode 1310 nm black

The ACT Fiber optic LC loopback adapter EA9004 is designed for singlemode operation at 1310 nm and comes in a durable black housing. Intended for testing and troubleshooting fiber optic links, this LC loopback provides a stable return path to verify transceiver and link behavior in data centres and telecommunications environments.

Advantages

The adapter supports singlemode 1310 nm testing, has a compact LC connector footprint and a robust black housing for repeated lab or field use. It enables quick verification of transmit/receive pairs without additional patchcords and helps isolate faults during maintenance.

Suitable for

• Loopback testing of singlemode fiber transceivers at 1310 nm
• Diagnostic checks in data centres and telecom racks
• Verification of transmitter/receiver functionality during equipment maintenance

Key specifications

How to use

Insert the LC loopback adapter into the LC receptacle of the transceiver or port to be tested, ensuring proper alignment of the connector. Once fitted, the adapter creates an optical loop that reflects the transmit signal back to the receiver, allowing link tests and diagnostics. Remove the adapter after testing and store it in a protective case to avoid contamination of the ferrule.

Recommendations

Keep connector endfaces clean and handle the adapter by the housing to prevent damage or contamination. Use in environments compatible with singlemode 1310 nm equipment and follow standard fiber-optic safety and ESD procedures.
