1. 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.

2. 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 sizeLC 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 lossUPC type ≥ 50dB, APC type ≥ 65dB, reducing signal reflection interference.
• durabilityThe plug-in life is usually more than 500 times, and the ceramic sleeve has a longer lifespan.

3. Type diversity

• Simplex/DuplexSimplex 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 selectionThe material of the sleeve is divided into ceramic (high precision, low loss) and plastic (low cost, easy production).

4. Application flexibility

• Wide range of scenariosSuitable for high-speed networks such as 40G/100G Ethernet, Fiber Channel (FC), and Synchronous Optical Network (SONET).
• compatibilitySupport for mixing LC connectors of different brands (subject to IEC standards).

5. Installation and maintenance

• Plug and PlayNo tools required, quick deployment.

• Modular designAdapt 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 requirementsEnd face contamination can lead to increased wear and tear, requiring regular cleaning with special tools.

  • plug-in specificationAvoid frequent insertion and removal of damaged sleeves or connectors.

  • Environmental adaptationMetal housing adapters provide enhanced EMI protection and are suitable for industrial environments.

IV. Typical application scenarios

1. Data CenterA high-density connection between the server and the switch.

2. 5G base station: Fiber optic wiring for the forward/return network.

3. security monitoringLink deployment of camera and video transmission equipment.

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