24 Fibers MTP Female Type 1 Fiber Loopback Module, OM4

This 24 loopback module provides a compact optical self test for parallel ports. It routes transmit lanes back to the receive lanes inside a rugged housing, so you can verify port function, run burn-in tests and diagnose link faults without a second device.

Product Highlights

• Fiber Type: OM4 50/125μm
• Fiber Connector: MTP® Female, UPC
• Insertion Loss: MM (BIF)≤1.2dB
• Return Loss: MM≥25dB
• Insert-Pull Test: 50times, IL Change<0.5dB
• Factory tested, individually packed

Typical uses are switch and NIC port validation in production, burn-in testing before shipment, troubleshooting suspect links in the field, and verifying cabling channels end to end. It lets a single technician confirm that a parallel port transmits and receives correctly on every lane.

Loopback testing isolates faults quickly: if the link comes up with the loopback installed, the port and transceiver are healthy and the problem lies in the cabling or far end. If it does not, the fault is local. This simple test saves hours of guesswork during commissioning.

Ordering is simple: send us LPM-OM4-24MTP and your required lengths and quantities, and we return a factory quote the same working day. Small trial orders are welcome before you commit to a full project rollout.

We do not ship untested product. Each unit is measured on calibrated equipment for optical performance and visually inspected for end face quality before packing. Batch traceability is maintained so any field issue can be tracked back to production.

Products are packed in anti-static or PE bags with connector dust caps fitted, then boxed in sturdy export cartons. Custom labels, barcodes and carton markings are available on request.

As a factory we can modify almost every detail of this product: length, jacket material and color, polarity, gender, breakout geometry, labeling and packaging. Non-standard variants are routine work for us, not a special project.
