Huawei Fiber Optic Composite Patch Cords are connected by linking the optical fiber to the optical module and the electrical conductors to the DC power port, using pre-terminated connectors or splicing as required.

Connection Overview

Huawei Fiber Optic Composite Patch Cords, such as OPGW hybrid cables used in FTTR solutions, integrate optical and electrical functionalities for simultaneous data transmission and remote power supply . The connection process involves both the optical fiber and the electrical conductors.

Optical Fiber Connection

1. Remove Dust Plugs: Before connecting, remove dust plugs from the optical ports on the device and the patch cord .
2. Install Optical Modules: Insert compatible Huawei optical modules (e.g., SFP+ or XC/UPC connectors) into the device ports .
3. Connect Fiber: Align the Tx (transmit) of the local device with the Rx (receive) of the peer device. Ensure the wavelengths of both optical modules match .
4. Splicing (if required): For field-terminable cables, splice the main hybrid cable with a pigtail using standard fiber splicing techniques. Minimize pigtail length and reserve sufficient cabling space .
5. Avoid Bending: Maintain a bend radius of at least 40 mm to prevent signal loss or fiber damage .

Electrical Connection

1. Prepare Power Conductors: Separate the two power cables at the end of the hybrid cable, exposing the copper cores (~7 mm), .
2. Insert into Phoenix Connector: Place the power cables into the provided phoenix connector. Tighten the screws to clamp the copper cores securely .
3. Connect to Device: Insert the phoenix connector into the DC power port of the device .

Installation Considerations

• Pre-Terminated vs Field-Terminated: Huawei offers pre-terminated cables with XC/UPC connectors for quick deployment, or field-terminable options for custom lengths .
• Routing: Route cables according to cabling requirements, using cable ties or clips to secure them. Avoid exposure to sunlight or excessive heat .
• Safety: Never look directly into the optical transmit interface to prevent eye injury .
• Flame Retardancy: Ensure indoor cables meet UL94-V0 standards for safety .

Summary

The Huawei Fiber Optic Composite Patch Cord connection method combines optical module insertion, fiber alignment, optional splicing, and electrical connection via phoenix connectors. Using pre-terminated cables simplifies installation, while field-terminable cables allow flexibility. Proper handling, bend radius maintenance, and safety precautions ensure reliable data transmission and power delivery in FTTR deployments .
