Micro Capillary Tube – Round, Square & D-Type

Micro capillary tubes, also called precision glass tube, fiber optic capillary tubes, are made of borosilicate glass with a cavity inserted whose accuracy is ±0.005 mm. Borosilicate glass is a special kind of glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. So borosilicate glass capillary tubes are widely used in optical communication industry as packaging materials of collimator, pigtail, DWDM and other optical passive device.

Precision glass tubes can be divided into three types according to outer shape:

  • Round type.
  • Square type.
  • D-type.
A round micro capillary tube with a cavity inserted on blue background.

MCT-01: Round type.

A square precision glass tube with a cavity inserted on blue background.

MCT-02: Square type.

Two d-type micro capillary tubes with a cavity inserted in each on blue background.

MCT-03: D-type.

Fiber optic capillary tubes can be mainly divided into three types according to the quantity of inserted cavity:

  • Single mode.
  • Dual mode.
  • Multiple mode.
Three round micro capillary tubes with a cavity inserted in each on a blue background.

MCT-04: Single mode.

Two transparent dual mode glass tube under the microscope.

MCT-05: Dual mode.

Seven round micro capillary tubes with seven cavities inserted in each on blue background.

MCT-06: Multiple mode.
