Abstract
A pluggable miniature optical passive device comprises a casing (30), an optical device (40) is mounted in the casing (30), a first end of the optical device (40) is provided with a first ceramic ferrule (43). At least one fiber core (432) is provided in the first ceramic ferrule (43), a first end (41) of the first ceramic ferrule (43) extends out of the casing (30). A second end (42) of the first ceramic ferrule (43) is positioned in the optical device (40), and the second end (42) of the first ceramic ferrule (43) is coated with an antireflection film, a lens (45) is provided close to the second end (42) of the first ceramic ferrule (43), the lens (45) is positioned in the optical device (40). At least one optical fiber is further provided in the optical device (40), a first end of the optical fiber is provided at a side close to the lens (45) and away from the first ceramic ferrule (43), a light beam incident in the optical fiber of the optical device (40) via the ceramic ferrule (43) and the lens (45). The pluggable miniature optical passive device has a small volume, and low manufacturing cost and long service life.
