SMUGDESK 25PCS LC UPC Duplex Single-Mode Fiber Optic Coupler

SKU CH-CS0F-CT9T4

Pack of 25 LC UPC duplex fiber couplers that join two single-mode patch cables for extension or panel wiring

  • 25 couplers per pack support large-scale fiber deployments
  • LC duplex female-to-female design joins two patch cables for easy extension
  • Precision ceramic sleeves ensure low insertion loss and high return loss
  • Compact plastic housing fits patch panels, terminal boxes and network cabinets
  • Optimized for single-mode UPC connectors in data center, FTTH and telecom networks

Bulk pack of 25 LC UPC duplex couplers

This pack supplies 25 LC UPC duplex fiber optic adapters for single-mode networks. Each unit joins two LC duplex patch cords to extend cable runs or organise links inside patch panels and cabinets. The bulk quantity suits data-centre installs, FTTH roll-outs and campus network builds.

Single-mode only, no APC support

The couplers accept LC UPC single-mode connectors exclusively; they will not mate with APC angled end faces. Precision ceramic alignment sleeves give low insertion loss and high return loss for stable single-mode transmission. Compatibility is limited to the LC UPC duplex interface.

Extends cable runs in dense enclosures

The compact plastic housing saves rack space compared with larger adapter types and fits standard patch-panel cut-outs. It handles typical single-mode link distances found in enterprise and telecom deployments. Very long-haul or ultra-low-loss specialist links may require tighter-tolerance components.
