Three-Pack ST/UPC to LC/UPC Adapter

This three-pack provides ST/UPC male to LC/UPC female hybrid adapters for single-mode 9/125 µm fiber. Each unit joins an ST patch cable to an LC patch cable in telecommunications, CATV, optical measurement or maintenance projects. The ceramic-and-metal sleeve withstands over 1000 mating cycles across a -40 °C to +95 °C operating range.

Insertion Loss 0.2 dB at 1310/1550 nm

The decisive specification is the low insertion loss of 0.2 dB at both 1310 nm and 1550 nm wavelengths, paired with 50 dB return loss. These figures confirm the adapter meets transmission requirements for standard single-mode links without adding significant attenuation.

Visual Fault Locator Continuity Testing

Beyond simple cable coupling, the adapters enable continuity checks on ST or LC patch cords using a visual fault locator. This built-in diagnostic capability lets technicians verify fiber paths quickly during installation or troubleshooting without extra test hardware.

Questions about this item

What does the 0.2 dB insertion loss mean when the adapter is installed in a live link?

At 1310 nm and 1550 nm the adapter adds only 0.2 dB of loss, so the signal budget is barely affected in single-mode runs.

Which polish and wavelength specs govern the return loss on this hybrid connector?

Both ST/UPC and LC/UPC faces are polished for 50 dB return loss at 1310 nm and 1550 nm.

What physical space and temperature range must the patch panel allow for these adapters?

Ceramic-sleeve simplex bodies fit standard bulkhead cut-outs and operate from -40 °C to 95 °C.
