How to use the jumper optical module

To jumper an optical module, select a compatible fiber optic jumper, match the module's wavelength and connector type, and connect carefully while avoiding excessive bending or contamination.

Selecting the Right Fiber Jumper

Before connecting, ensure the fiber jumper matches the optical module's specifications:

• Transmission medium: Single-mode fiber (yellow) for long distances, multimode fiber (orange) for short distances .
• Connector type: Common connectors include LC, SC, FC, ST, MPO, or MTP. Duplex modules require duplex jumpers, while simplex modules use single fibers .
• Wavelength and data rate: Ensure the jumper supports the module's operating wavelength (850nm, 1310nm, 1550nm) and data rate (10G, 25G, 40G, 100G, etc.), .

Connecting the Jumper

1. Insert the optical module into the device slot, ensuring the label faces the correct direction (up or down depending on the port), .
2. Attach the fiber jumper to the module's port, pressing until the latch clicks or securing with screws for FC/ST connectors .
3. Avoid bending the fiber excessively; maintain a minimum bend radius of 400mm to prevent signal loss .
4. Use protective caps on unused connectors to prevent dust or oil contamination .

Best Practices

• Ensure both ends of the jumper match the module's wavelength to prevent transmission errors .
• Keep jumper lengths appropriate for the installation, avoiding unnecessary slack or tight loops .
• For duplex connections, maintain correct polarity: transmit (Tx) to receive (Rx) and vice versa .
• When removing a jumper, press the clip or handle gently and wait at least 0.2 seconds before reinserting to avoid damage . By following these steps, you can safely and effectively jumper an optical module, ensuring reliable optical signal transmission and minimizing insertion loss or damage to the fiber connectors.
