Fiber optic splice closure knowledge brief Published 23 Mar 2024

Prepared for preliminary research by the RIVO OPTICAL knowledge desk. Confirm cable count, splice capacity, sealing class, tray layout, protection sleeves and installation requirements against current standards and product documentation.

FA Fiber Array Inspection uses specialized endface inspection equipment like the FA-1 to ensure high-quality fiber array endfaces for optical modules and PLC coupling.

Overview of FA Fiber Array Inspection

Fiber Array (FA) inspection is a critical process in the production of optical modules, including 40G and 100G transceivers, and in PLC (Planar Lightwave Circuit) coupling. The inspection ensures that the endfaces of multiple optical fibers in an array are free from defects such as scratches, chips, or contamination, which could compromise optical signal transmission and coupling efficiency .

FA-1 Fiber Array Endface Inspector

The FA-1 is a widely used fiber array endface inspection device developed by Dimension Technology and other manufacturers like Sunma. Key features include:

  • High Magnification: 300X optical magnification allows detection of minute scratches and defects .
  • Optical Quality: Uses optical systems comparable to Easycheck, providing clear and stable images without frequent refocusing .
  • Fixture Design: Patented 3D platforms and adjustable fixtures accommodate different polish angles and fiber array sizes, improving inspection efficiency and reducing operator fatigue .
  • Applications: Suitable for inspecting 4, 6, 16, 32, 64, and 128-core fiber arrays, as well as PLC chip endfaces .
  • Operational Efficiency: The design allows quick replacement of fiber arrays and consistent positioning, enhancing throughput in manufacturing environments .
Fiber Array Polishing and Preparation

Before inspection, fiber arrays undergo polishing processes to achieve optimal surface flatness and optical performance. Common methods include:

  • Two-step Polishing: Rough polishing followed by fine polishing, achieving surface flatness
