SKU CH-BCSA-69HCH

Pack of 25 SC/UPC simplex single-mode couplers with zirconia ceramic ferrules for joining patch cords in panels

  • Connect two single-mode patch cords with 25 SC/UPC keystone couplers
  • Low 0.2 dB insertion loss keeps signal strong across the link
  • High 50 dB return loss minimises back-reflection in the network
  • Zirconia ceramic ferrule resists heat and acid for durable mating
  • Rated for 1000 mating cycles across 1200-1600 nm wavelength range

SC/UPC Coupler Pack — 25 keystone modules

This pack contains twenty-five SC/UPC simplex single-mode fiber couplers in a keystone form factor. Each module joins two SC/UPC patch cords for use in patch panels or wall plates. Network installers and integrators building single-mode infrastructure will find the quantity suited to multi-drop deployments.

Low-loss ceramic ferrules under continuous traffic

Zirconia ceramic sleeves rated for heat and acid resistance keep insertion loss at 0.2 dB and return loss at 50 dB across the 1200–1600 nm window. Interchangeability stays within 0.2 dB after repeated mating cycles. The design is rated for one thousand insertions without degradation.

Keystone footprint fits standard panels

The coupler snaps into any keystone cut-out on patch boards or wall panels, requiring no tools beyond a punch-down screwdriver for the panel itself. Alignment keys on the SC interface prevent cross-connection. The only common issue is dust on end-faces, so clean both connectors before mating.

Questions about this item

Does the ceramic ferrule in the SC/UPC keystone jack add heat or noise when the patch panel runs all day?

The zirconia ceramic sleeve is heat-resistant and acid-resistant with no moving parts, so it produces no noise and adds no measurable heat during continuous operation.

What cables must I already have to use these 25 keystone couplers in a patch board?

You need single-mode SC/UPC patch cords on both sides; each coupler joins two such cords in a simplex connection.

Will these SC/UPC couplers work with the older SC/APC patch cords I have in the rack?

No — the keystone jacks are SC/UPC only, so they cannot mate with angled-polish SC/APC connectors without excessive return loss.
