Product Detail

LC Fiber Optic Adapter with Inner Shutter

The LC fiber optic adapter with inner shutter is a high-performance optical coupler designed to connect two LC fiber optic connectors while ensuring precise alignment and reliable signal transmission. LC adapters are widely used in high-density fiber networks such as data centers, FTTH infrastructure, telecom systems, and optical distribution frames.

This LC duplex adapter features an internal metal shutter mechanism, which automatically blocks the laser beam when no connector is inserted. This safety design protects technicians from laser exposure and also prevents dust from entering the adapter port. According to industry specifications, fiber optic adapters typically use a ceramic or phosphor bronze sleeve to ensure accurate fiber alignment and low insertion loss.

ANFKOM LC fiber adapters offer stable optical performance with low insertion loss, excellent repeatability, and long durability for over hundreds of mating cycles. They are available in multiple configurations including simplex, duplex, flange, and flangeless designs, making them suitable for patch panels, optical cabinets, and fiber termination boxes.

LC fiber optic adapters with inner shutters are widely used in high-density fiber networks to improve safety and performance. For a broader overview of available types, specifications, and applications, explore our complete range of fiber optic adapters.

Advantages of Inner Shutter Fiber Adapters

The inner shutter design provides several benefits compared with standard fiber adapters:

• Laser safety protection – prevents laser light leakage
• Dust protection – keeps the optical port clean
• Improved reliability – protects the ferrule from contamination
• Higher safety for technicians during maintenance
• Better long-term optical performance

This type of adapter is commonly used in data centers, telecom cabinets, and fiber distribution frames.

FAQ

What is an LC fiber optic adapter?
An LC fiber optic adapter is a passive device used to align and connect two LC fiber connectors to extend fiber optic links.

What is the purpose of the inner shutter?
