Fiber Array (FA) 4CH 42.5° for 400G Optical Modules

Description

Fiber Array (FA) is an assembly in which multiple optical fibers are arranged at a defined channel pitch and precisely fixed onto a V-groove substrate. This model assembles a single 4-fiber ribbon onto the V-groove substrate at a defined pitch and polishes it into a 42.5° endface, used for fiber coupling inside 400G optical modules, which significantly reduces the coupling alignment loss of the waveguide device.

Product Features

• 4 channels with a 42.5° endface, used for fiber coupling inside 400G optical modules
• Single 4-fiber ribbon assembled with neat pigtail routing
• Channel pitch accuracy and endface quality are controlled, with good batch-to-batch consistency
• Ribbon color and pigtail length can be customized to requirement

Typical Applications

• Fiber coupling and alignment inside 400G optical modules
• AWG and WDM devices
• High-density optical modules and optical engines

Materials & Process

• V-groove substrate: quartz (JGS2, Borofloat 33, etc.) or silicon, precision-grooved to form V-shaped channels
• Fiber: standard singlemode fiber or polarization-maintaining fiber; pigtails or patch cords can be added per application
• Fixing and bonding: after the fibers are placed in the V-grooves they are secured with low-shrinkage, low-stress UV or epoxy adhesive
• Endface polishing: endface flatness and fiber height are controlled; 0°, 42.5° and protruding-fiber endfaces are supported

Note: A / B / C are array reference-face dimensions — the customer drawing governs. Ribbon color and pigtail length can be customized to requirement.

Customization and quotation: this product is built to drawing. Channel count, pitch, substrate size and material, and endface angle can all be specified.
