GoodConnections acoplador de fibra óptica LC/APC a LC/APC dúplex, carcasa SC simplex, plástico verde, monomodo, casquillo de circonia LW-KULCAPCK

For fibre links that demand stable low-loss mating without panel clutter, this GoodConnections duplex coupler pairs two LC/APC ports in a single SC-simplex cut-out. The green plastic body follows the APC colour convention, while the zirconia ceramic sleeves keep insertion loss under 0.2 dB and return loss above 60 dB across more than 500 mating cycles. Unlike generic adapters, it is built for single-mode OS2 paths where angled physical contact is non-negotiable.

Highlights

• Duplex LC/APC to LC/APC alignment in an SC-simplex housing footprint
• Zirconia ceramic sleeves for repeatable, low-loss connections
• Typical insertion loss below 0.2 dB; return loss above 60 dB
• Green plastic housing for instant APC identification
• Panel-mount design for FTTx, LAN, data centre and telecom use

In daily use

Installation is straightforward: clip the coupler into any standard SC-simplex panel cut-out and connect LC/APC patch cables from both sides. The duplex layout keeps transmit and receive fibres paired, reducing cable clutter in high-density fibre management. The angled polish minimises back reflections, making it suitable for RF-over-fibre, PON and other single-mode applications where signal integrity matters. The all-plastic housing resists everyday handling while remaining lightweight for large deployments.

Final note

GoodConnections engineered this coupler for technicians who refuse to compromise on return loss. The green SC-simplex body saves panel space while the duplex LC/APC interface keeps single-mode performance consistent from first insertion to last.
