ProLink PL‑CSC‑D‑SM — Fiber Optic Coupler, SC‑SC Duplex, Single‑Mode (SM)
The ProLink PL‑CSC‑D‑SM is a single‑mode SC‑SC duplex fiber optic coupler for terminating and joining SC duplex single‑mode patch cables in fiber panels and termination boxes — featuring zirconia ceramic alignment sleeves, low insertion loss, and high return loss. Designed for telecom, LAN/WAN, and data center passive fiber networks.
Description
ProLink PL‑CSC‑D‑SM — Single‑Mode SC‑to‑SC Duplex Fiber Coupler (SM, 9/125 µm)
Key Features:
Duplex SC‑SC Connectivity — Allows mating of two SC duplex single‑mode patch cables without conversion or adapters.
Single‑Mode Compatible (9/125 µm) — Designed for low‑attenuation single‑mode optical links.
Zirconia Ceramic Alignment Sleeves — Ensures precise fiber alignment for reliable optical performance.
Low Insertion Loss — Minimizes signal loss across the coupler interface.
High Return Loss — Helps reduce back reflections for stable SM optical connections.
Compact, Panel‑Friendly Design — Suited for mounting in fiber patch panels, termination boxes, or bulkhead panels.
