High-Precision FC fiber Adapter – Durable Fiber Optic Coupler for Fast & Stable Connections

3 Requirement

3.1 Meet IEC_61754-13

3.2 Meet GR-326 core

3.3 Flame Rating: UL94-V0

3.4 ROHS compliance：RoHS2.0 & REACH

First, the core functions of the FC adapter

mechanical connection

Connectors (such as FC jumpers and pigtails) are tightly connected through a threaded structure to ensure stable transmission of optical signals.

end face alignment

The internal ferrule precisely aligns the connector end face, supports PC, UPC, APC and other end face types, and reduces reflection loss.

II. Main features

Structural characteristics

Thread locking: Metal threaded sleeve is used to provide high stability and is suitable for severe environments with vibration or frequent movement.

Round shell: The size is 2.5mm (the same as the ST adapter), but it is bulky and has lower space utilization than the LC.

Performance parameters

Low insertion loss: Single-mode typical value ≤ 0.3dB, multi-mode ≤ 0.5dB.

High return loss: PC type ≥ 45dB, UPC type ≥ 50dB, APC type ≥ 65dB (depending on the end face process).

durability: Plugging and unplugging life is usually more than 1000 times, and the metal structure has strong wear resistance.

Type diversity

Simplex/Duplex: Simplex adapts to a single connector, duplex integrates two independent channels.

Single mode/multimode: Adapt to different fiber types (single mode: 9/125μm; multimode: 50/125μm or 62.5/125 μm).

Material selection: The sleeve is made of ceramic (high precision) or metal (low cost), and the shell is mostly metal.

Application flexibility

Wide range of scenarios: Applicable to 1G/10G Ethernet, SDH/SONET transmission, video transmission, etc.

compatibility: Comply with IEC standards and support mixed insertion of different brands of FC connectors.

Environmental adaptability

high reliability: Threaded structure anti-loosening, suitable for industrial control, outdoor base station and other scenarios.

EMI protection: Metal shell shields electromagnetic interference to enhance signal stability.

III. Advantages and Precautions

advantage

Solid connection: Thread locking to avoid accidental disconnection, suitable for vibration environment.

Low loss: Ceramic sleeve ensures accurate docking of end faces and high transmission efficiency.

durability: Metal material is resistant to corrosion and has a long lifespan.

Precautions

plugging and unplugging time: The thread needs to be rotated and fixed, and the operation speed is slow.

Space occupancy: Large size, not suitable for high-density wiring.

Cleaning requirements: End face contamination can lead to increased wear and tear, requiring regular maintenance.

IV. Typical application scenarios

telecommunications network: Long-distance transmission link for SDH/DWDM systems.

CATV system: Optical signal distribution for cable television networks.

Industrial Control: Sensor connections for factory automation equipment.

Traditional data center: Maintenance of legacy systems for early network deployments.
