Huawei Fiber Optic Module Patch Cord Connection Method

Fiber and communications infrastructure knowledge brief Published 13 Sep 2024

Prepared for preliminary research by the ROGER FIBRE knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Huawei fiber optic patch cords are connected by matching the correct connector type to the optical module, ensuring proper polarity, and following pre-terminated or splicing procedures for hybrid cables.

Connection Overview

Huawei fiber optic patch cords, including pre-terminated XC/UPC or hybrid OPGW cables, are designed for FTTR (Fiber To The Room) and indoor deployments. They integrate optical data transmission with electrical power supply in hybrid cables, allowing non-fusion splicing installation for indoor conduit wiring. Proper connection ensures minimal signal loss and reliable network performance.

Step-by-

Step Connection Method

Prepare the Device and PortsRemove dust plugs from idle optical ports on the device (e.g., AP, ONU, or OLT). Install optical modules compatible with the patch cord (LC, SC, or XC/UPC connectors) into the device.

Check Cable Type and Polarity

Ensure the patch cord matches the fiber type: single-mode for long distances, multimode for short intra-data center links. Confirm connector type compatibility with the optical module (LC, SC, MPO/MTP, or XC/UPC). For duplex connections, maintain correct Tx/Rx orientation to avoid signal mismatch.

Connect the Patch Cord

Insert the fiber connector into the optical module until it clicks securely. For hybrid cables, separate the optical fiber from the power lines and connect the phoenix connector to the DC power port, tightening screws to secure the copper core. Route the cable according to cabling requirements, minimizing pigtail length and leaving sufficient slack for maintenance.

Secure and Test

Bundle cables using cable ties and avoid sharp bends to prevent fiber damage. Test the optical link using an optical power meter or OTDR to verify signal integrity and low insertion loss.

Optional Splicing

If using a hybrid cable that requires splicing, splice the main cable with the pigtail using standard fiber splicing techniques. Minimize pigtail length and ensure proper strain relief.

Best Practices

Dust Protection: Always keep dust caps on unused ports to prevent contamination. Connector Care: Avoid touching the fiber end-face; clean connectors with alcohol wipes if necessary. Cable Management: Use proper bend radius and secure cables to prevent microbends or macrobends that can increase loss.

Compatibility Check: Verify that the patch cord, optical module, and device are compatible in terms of fiber type, connector type, and distance requirements. By following these steps, Huawei fiber optic patch cords can be connected efficiently, ensuring high reliability, low latency, and optimal network performance.
