Singlemode Duplex Patch Cable

This one-meter duplex patch cable uses 9/125 µm singlemode fibre with ST connectors on both ends. It is built to OS1 specifications for high-speed, long-range data and voice transmission in professional networking environments.

Suited for short singlemode links

Network technicians who need a compact, low-loss link between singlemode transceivers, patch panels or distribution frames will find the 1 m length convenient. Installations that require angled-polish connectors, multimode fibre or longer cable runs should select a different product.

Fits tight singlemode pathways

The 10 mm minimum bend radius allows routing in dense racks or wall boxes without exceeding mechanical limits. UPC ferrules keep insertion loss at or below 0.35 dB and return loss at or above 55 dB, preserving signal integrity across the connection.

Highlights

  • Low insertion loss of ≤ 0.35 dB per connector

Questions about this item

What equipment must I already have to use this 1 m OS1 ST/ST patch lead?

You need devices with ST ports that accept 9/125 µm singlemode fibre, such as transceivers, patch panels or media converters.

How does this singlemode cable behave when connected to older 9/125 µm OS1 hardware I still use?

It meets the same OS1 specifications, so insertion loss stays ≤ 0.35 dB per connector and return loss remains ≥ 55 dB on legacy links.

How can I confirm the 1 m ST/ST link is performing within spec after installation?

Measure each connector with a singlemode light source and power meter; loss should read ≤ 0.35 dB and return loss ≥ 55 dB.
