LC fiber optical adapter – Compact Fiber Optic Coupler for High-Density Network Solutions

LC series optical adapters are available in 5 different specifications:

1：LC Standard Adapter Specification

2：LC Duplex Adapter(SC Type)

3：LC Quad Adapter Specification

4：LC Quad Adapter With Shutter

5：LC Duplex Adapter With Shutter Specification

The following is a detailed description of the LC optical adapter:

First, the core functions of the LC adapter

linkage

As an intermediary device, it is used to precisely connect two LC connectors (such as fiber optic jumpers, pigtails, or cable ends) to ensure low-loss transmission of optical signals.

end face adaptation

Align the connector end face through the internal sleeve (ferrule), support PC (physical contact), UPC (meta-physical contact), APC (angular physical contact) and other end face types to reduce reflection loss.

II. Main features

1. Miniaturized design

Compact size: LC connector size is 1.25mm (smaller than SC's 2.5mm), and the adapter is smaller, making it suitable for high-density wiring environments.

High space utilization: More ports can be integrated into the rack or distribution box, saving space costs.

2. High performance parameters

Low insertion loss: Typical value ≤ 0.3dB (multimode) or ≤ 0.5dB (single mode).

High return loss: UPC type ≥ 50dB, APC type ≥ 65dB, reducing signal reflection interference.

durability: The plug-in life is usually more than 500 times, and the ceramic sleeve has a longer lifespan.

3. Type diversity

Simplex/Duplex: Simplex adapts to a single connector, and Duplex integrates two independent channels to support bidirectional transmission.

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

Material selection: The material of the sleeve is divided into ceramic (high precision, low loss) and plastic (low cost, easy production).

4. Application flexibility

Wide range of scenarios: Suitable for high-speed networks such as 40G/100G Ethernet, Fiber Channel (FC), and Synchronous Optical Network (SONET).

compatibility: Support for mixing LC connectors of different brands (subject to IEC standards).

5. Installation and maintenance

Plug and Play: No tools required, quick deployment.

Modular design: Adapt to panels, couplers, attenuators, and other devices for easy network expansion.

III. Advantages and Precautions

advantage

High density: saves more than 50% of space compared to connectors such as SC and ST.

Low cost: Modular design reduces overall wiring costs.

Easy to manage: Color coding (e.g. blue for multimode, yellow for single mode) makes it easy to distinguish.

Precautions

Cleaning requirements: End face contamination can lead to increased wear and tear, requiring regular cleaning with special tools.

plug-in specification: Avoid frequent insertion and removal of damaged sleeves or connectors.

Environmental adaptation: Metal housing adapters provide enhanced EMI protection and are suitable for industrial environments.

IV. Typical application scenarios

Data Center: A high-density connection between the server and the switch.

5G base station: Fiber optic wiring for the forward/return network.

security monitoring: Link deployment of camera and video transmission equipment.

FTTH (Fiber to the Home): End point box installation for home broadband access.
