Quantum Communication E2000 Connector Intelligent Type

The E-2000® connector is a high-precision fiber-optic connector with ultra-low insertion loss, spring-loaded shutters, and advanced alignment technology, ideal for critical quantum communication applications.

Key Features

Active Core Alignment (ACA) Technology: The E-2000® connector uses Diamond's patented ACA system, which ensures the fiber core is perfectly centered, achieving ultra-low insertion loss (typically ≤ 0.1 dB) and high return loss, critical for quantum communication where signal integrity is paramount . Spring-Loaded Shutters: The connector includes spring-loaded metal shutters that protect the ferrule end-face from dust and scratches while preventing exposure to potentially eye-damaging laser radiation . This feature is essential for maintaining optical performance in sensitive quantum systems. Push-Pull Locking Mechanism: The connector employs a secure push-pull latch system with color-coded frames for easy identification and error-free connections, supporting both simplex and duplex configurations . Optical Interface Variants: E-2000® connectors support a wide range of optical interfaces, including standard singlemode, multimode, polarization-maintaining (PM), VIS/NIR, and expanded-beam solutions. APC versions feature an 8° oblique polished ferrule for low back reflection, which is particularly important in quantum communication networks . Environmental and Sterilization Options: The connector can be sterilized using EtO and offers optional IP65 O-ring sealing for rugged and hygienic environments, ensuring reliability under harsh conditions .

Performance Specifications

• Insertion Loss: Typically ≤ 0.1 dB with ACA technology; standard UPC versions around 0.20 dB .
• Return Loss: ≥ 50 dB for UPC, ≥ 60 dB for APC .
• Operating Temperature: -25°C to +75°C .
• Durability: Designed for repeated mating cycles with consistent optical performance.

Applications in Quantum Communication

The E-2000® connector's precision alignment, low insertion loss, and high return loss make it suitable for quantum key distribution (QKD) and other quantum communication systems where photon-level signal integrity is critical. Its dust and laser protection shutters and robust mechanical design ensure stable performance in laboratory and field deployments.

Summary

The Quantum Communication E2000 Connector (Intelligent Type) leverages the advanced features of the E-2000® family, including ACA alignment, spring-loaded shutters, push-pull locking, and environmental sealing, making it a reliable choice for high-precision, low-loss optical networks in quantum communication applications .
