  • Low insertion loss of 0.2 dB preserves signal strength
  • High return loss of 25 dB minimises back-reflection

Alphacool ST-ST Simplex Coupler Pack

This pack contains fifty simplex ST to ST couplers designed to join two single-mode fibre patch cords in a straight line. Network engineers and installers use them to extend links inside server racks, patch panels or optical distribution frames.

Low Loss Across Wide Temperature Range

Each coupler achieves an insertion loss of .2 dB and a return loss of 25 dB, maintaining those figures from minus 20 up to 70 degrees Celsius. Interchangeability loss stays at .25 dB and repeatability at .15 dB even after repeated mating cycles.

Screw Nut Mounting With Dust Protection

The screw nut mounting style locks each adapter firmly into standard rectangular panel cut outs. A dust cap ships on every unit to keep the ceramic ferrule clean during storage and installation. Rated for more than 1000 mating cycles.

Questions about this item

Does the 0.2 dB insertion loss stay consistent during continuous operation?

The coupler is rated for an operating temperature range of -20 to 70 and maintains 0.2 dB insertion loss across that range.

What type of fibre patch cords are required to use these 50 simplex ST-ST couplers?

You need single-mode fibre cables terminated with ST connectors on both ends to mate with the female-to-female UPC adapters.

Will the zirconia ceramic sleeves survive repeated re-patching alongside older ST hardware?

The sleeves are rated for more than 1000 mating cycles with 0.15 dB repeatability, so they handle frequent changes on legacy ST links.
