The discrimination unit discriminates a type of each of a pair of optical fibers based on a plurality of feature amounts obtained from imaging data provided from the imaging unit. The discrimination unit adopts a discrimination result by any of first and second discrimination algorithms. The first discrimination algorithm is predetermined by a method other than machine learning. The second discrimination algorithm includes a discrimination model. The discrimination model is created by machine learning using sample data. The splicing unit fusion-splices the pair of optical fibers to each other under a splicing condition according to a combination of the types of pair of optical fibers based on a discrimination result in the discrimination unit.

An adapter is configured to hold a loose tube fiber cable and is mountable into a fusion splicer. The adapter includes a clamp base having a first and second grooves, each groove having a centerline, a width and a depth. The depth of the second groove is greater than the depth of the first groove, such that a shoulder is formed between the first and second grooves. The centerlines of the grooves align. This allows for the loose tube fiber cable or splice-on connector to be properly positioned within the grooves. The first groove is V-shaped. The second groove may be V-shaped, U-shaped or square-shaped. A clamp cover seats on the clamp base. The clamp cover has a compressible pad which, when the clamp cover is placed into a facing relationship with the clamp base, the pad aligns with the first groove.

Techniques for aligning each of a plurality of optical fibers for coupling to a photonic integrated circuit (PIC). Transmission is detected from each respective optical fiber to the PIC using a probe, and the respective optical fiber is aligned based on the detected transmission. Each of the plurality of optical fibers is coupled to the PIC using at least one of: (i) laser splicing, (ii) laser spot welding, or (iii) arc welding.

An optical fiber alignment mechanism (100) operates to align optical fibers (102). The mechanism can include a key element (120, 130) arranged on the cladding (112) of an optical fiber (102). The key element (120, 130) can engage with a corresponding element of another optical fiber (102) to align the cores (108) of the mating optical fibers. The key element (120) of an optical fiber (102) can also be inserted into a corresponding keyway (226) of a fiber alignment hole (222) of a ferrule (200) such that the optical fiber (102) is oriented properly within the ferrule (200).

A ribbon transition tool modifies a 200 μm ribbon for splicing to a 250 μm ribbon. A spreader comb is fixedly mounted at the front end of the base of the tool. A straight comb is slidably mounted to the base behind the spreader comb. The combs each have a plurality of fiber channels corresponding to the fibers in the fiber ribbon. At the front end of the spreader comb, the channels have a spacing matching the initial spacing of the fiber ribbon. At the rear end of the spreader comb and throughout the straight comb, the channels have a spacing matching the modified spacing. An anvil is mounted into the base so as to be movable between a lowered position, in which the anvil lies underneath the straight comb, and a raised position, in which the anvil fills the gap between the combs when they are separated.
