Five yellow 3 metre duplex fibre patch cords SC UPC to LC UPC

Adafruit

Adafruit 5-pack SC UPC to LC UPC duplex OS2 9/125 fibre patch cords 3 m

SKU CH-8GA2-8WT6Z

Pack of five 3-metre duplex OS2 single-mode fibre patch cords with SC UPC to LC UPC connectors, 0.3 dB insertion loss and LSZH jacket

  • Five cords simplify multi-link installs
  • Low 0.3 dB insertion loss keeps signals strong
  • 50 dB return loss cuts reflection noise
  • A-B markings speed fault finding
  • LSZH jacket resists flame and smoke

Five-pack OS2 single-mode patch cords

This five-pack supplies 3-metre duplex cables with SC UPC connectors on one end and LC UPC on the other. The 9/125 µm G652D fibre core operates at 1310 nm and 1550 nm wavelengths for single-mode links. They suit installers or network managers who need multiple identical jumpers for patch panels or equipment racks.

LSZH jacket and ceramic ferrules

Each cord uses a 3.0 mm low-smoke zero-halogen outer jacket over a 0.9 mm buffered fibre with para-aramid strength yarn. A-grade zirconia ceramic ferrules deliver 0.3 dB insertion loss, 50 dB return loss and 0.2 dB repeatability. The assembly is rated for -20 °C to 70 °C operation.

A-B markings simplify polarity

Duplex cables carry A-B markers so transmit and receive fibres stay matched during moves or fault finding. Verify that your patch panels and transceivers accept SC UPC and LC UPC single-mode connectors before ordering. These cords do not support multimode systems or angled-polish interfaces.

Questions about this item

What wavelength range does the OS2 9/125 fibre support for single-mode transmission?

The patch cords use G652D fibre that supports 1310nm and 1550nm wavelengths, covering the standard single-mode operating windows.

What are the connector dimensions and jacket size for rack or panel mounting?

Each duplex cord has SC UPC and LC UPC connectors with zirconia ceramic ferrules, a 0.9 mm buffered fibre, and a 3.0 mm LSZH outer jacket.

How do I identify the correct Tx and Rx fibres when installing the duplex patch cords?

The cables include A-B markings on the duplex clips; match the A leg to the transmitter port and the B leg to the receiver port to avoid crossed fibres.
