MPO Fiber Optic adapter

The Multi-fiber Push On Adapter is a high-density connectivity solution designed for MPO/MTP type multi-fiber connectors, widely used in data centers, 40/100/400G Ethernet, Fibre Channel (FC) and parallel transmission systems. Its unique multi-core integrated design significantly increases cabling density and becomes a key component for high-speed network deployments.

 Parameter:

The following is a detailed introduction and a point-by-point description of its characteristics:

First, the core functions of the MPO adapter

1. multichannel parallel transmission
   Multi-core optical fibers (e.g. 12-core, 24-core) are supported through a single connector to achieve simultaneous transmission of multiple signals to meet high bandwidth requirements.

2. Precise end face alignment
   The MT (Mechanical Transfer) sleeve design is adopted to ensure accurate alignment of multiple fiber end faces (e.g. PC, UPC, APC) and reduce insertion loss.

3. polarity management
   Control the direction of the connector through key design to avoid polarity errors, and support Method A/B/C and other polarity schemes.

II. Main features

1. High-density design

• multicore integrationSingle adapter supports 12/24/48 core fiber, and the space efficiency is 4-8 times that of LC.
• Compact structure: Width of about 12.7mm (12 cores), thickness of only 3-4mm, suitable for rack-type dense wiring.

2. Performance parameters

• Low insertion loss：
  • 多模（OM3/OM4）：≤0.5dB（典型值）
  • 单模（OS2）：≤0.7dB（典型值）
• High return lossUPC type ≥ 60dB, APC type ≥ 70dB (reduce reflection interference).
• durability: Insert and unplug life more than 500 times (depending on the material of the sleeve).

3. Type diversity

• core number selection: 12 cores (mainstream), 24 cores (high density), 48 cores (ultra-high speed).
• End face type: PC (physical contact), UPC (metaphysical contact), APC (angular physical contact).
• schema support: Multimode (50/125μm, 62.5/125 μm), single mode (9/125μm).

4. Polarity management

• key designMake sure the transceiver channels are paired correctly through different key combinations (e.g. Type A/B/C).
• compatibility standard: Support IEC 61754-20 and TIA-604-10 specifications, suitable for mainstream equipment.

5. Application extensibility

• Modular supportCan be integrated into wiring frame, Coupler, attenuator, splitter and other equipment.

• Easy to expandCompatibility with single-core systems is achieved through MPO-LC conversion lines.

III. Advantages and Precautions

• advantage
  • high densitySingle port supports multiple channels, saving rack space.
  • Easy to expandSupport 40G/100G/400G network smooth upgrade.
  • Low lossMulti-core parallel transmission reduces overall link loss.
• Precautions

  • Cleaning requirements: Multi-core end face contamination will cause all channel performance to decline, requiring special cleaning tools.

  • polarity matchingThe polarity scheme required by the equipment must be strictly followed (e.g. Method B).

  • plug and unplug toolSpecial plugging and unplugging tools are recommended to avoid fiber damage.

IV. Typical application scenarios

1. Data CenterThe core switching area of 40G/100G Ethernet and InfiniBand networks.

2. 5G transmissionHigh-density wiring for front-pass/middle-pass/return networks.

3. Supercomputer CenterDirect fiber connection of parallel computing nodes.

4. Optical Fiber Distribution Frame (ODF)Termination and skipping of multi-core optical cables.
