inear Fiber Array #linear #fiber #array One dimensional linear fiber array is made by placing M / MM / PM fibers on a V-grooved substrate at specified spacing ( pitch ). As for these V groove fiber arrays, or the so-called optical V groove array, they are normally fixed into the grooves with epoxy and pressed by a glass cover. The fiber array facet of the optical fiber V groove array is always polished to meet the desired precision and during the production, active alignment is also used to ensure the correct alignment of fibers so that the fibers can be arranged in a certain order to form an optical fiber array.

As a professional fiber manufacturer, MEISU offers the most extensive selection of linear fiber arrays for different applications by providing customizable V-groove block & id, precise fiber core pitch, various fiber types, and flexible channel numbers. At here, all the linear v groove fiber arrays will be featured with accurate fiber core position and low insertion loss. As for the linear fiber arrays produced by MEISU, they can be effectively used in the high-speed transceiver, WSS, electronic, Lidar, and imaging.

Linear Fiber Array Features


One dimensional linear fiber array is made by placing M/MM/PM fibers on a V-grooved substrate at specified spacing (pitch). As for the linear fiber array units, they can be configured in virtually any cross-section imaginable and the two ends of the linear fiber arrays may have different cross-sections. During the production of linear V groove fiber arrays, fibers are fixed into the grooves and pressed by a glass cover (lid). The material for v-grooved substrate and lid can be borosilicate glass, fused quartz or silicon. To meet the desired precision, the fiber array facet will normally be polished of any angle needed and active alignment will also be used to ensure the correct alignment of fibers while they are arranged in a certain order to form an optical fiber array.

As a professional manufacturer, MEISU offers the most extensive selection of fiber arrays for different applications by providing customizable V-groove block & lid, precise fiber core pitch, various fiber type, and flexible fiber counts. All the linear fiber arrays produced by MEISU will be featured with both accurate fiber core position and low insertion loss. Moreover, they will also be tailored for both technical and economic requirements. As for the use of MEISU's linear fiber arrays, they can be utilized in a high-speed transceiver, WSS, electronic, Lidar and imaging.

Linear Fiber Array FAQ
What Is The Materials For The V-grooved Substrate And The Lid?
What Is The Materials For The V-grooved Substrate And The Lid?
Borosilicate glass, Quartze or Silicone.

What Is The Smallest Core Pitch You Can Achieve?
It depends on the fiber cladding size, the core pitch is normally 2um bigger than the cladding diameter.

Is The Fiber Core Above Or Below The Top Surface Of The V-groove Substrate?
For regular 125um fiber, the fiber core is about 30 microns below the top surface of the substrate.

What Is The Thinnest Lid You Can Do?
The thinnest lid can be 0.1mm.

How Close Can The 0.9mm Protective Tubing Be To The V-groove Substrate ?
How Close Can The 0.9mm Protective Tubing Be To The V-groove Substrate ?
The minimum standard distance is 20 mm. If the customer needs all the fibers to be covered with protective tubing, we can add the metal case to the glass block and 0. 9mm tubing coming out of the case directly.
