Hybrid ST/SC Converter

The Vszerda two-pack provides ST/UPC male to SC/UPC female adapters for single-mode 9/125 µm fiber. Each unit bridges ST patch cables to SC equipment ports in test labs and LAN installations. The ceramic-and-metal sleeve withstands more than 1000 mating cycles.

Insertion Loss and Temperature

Typical insertion loss measures 0.2 dB at 1310 nm and 1550 nm with return loss of 50 dB at the same wavelengths. Operating temperature spans -40 °C to +95 °C. The UPC polish keeps reflections low across the working wavelength range.

Test Instrument Compatibility

Adapters connect ST and SC patch cords directly to visual fault locators and optical power meters for continuity checks. The hybrid interface converts instrument ports without additional cables. Flame-retardant housing suits bench and field use.

Questions about this item

How do I install the ST/UPC male to SC/UPC female adapter without damaging the ceramic sleeve?

Align the key on the ST male connector with the slot on the SC female port, push straight in until it clicks, and avoid twisting which can chip the ceramic sleeve.

What maintenance will these hybrid adapters need after repeated use in a test lab?

Inspect the ceramic sleeve and end-faces for scratches after every 1000 mating cycles; clean with a fibre-optic cleaning pen if insertion loss rises above 0.2 dB.

At what temperature limit does the adapter's performance degrade first during sustained operation?

The operating range tops out at +95 °C; beyond that the ceramic sleeve and metal housing can shift, raising insertion loss above the rated 0.2 dB.
