Are Hakusan 's SM MT Ferrule pre-angled?

No, the end face is flat. However, when actually connecting, the end face is polished at an angle. Also, it is compatible with pre-angled products from other manufacturers.

Is a special polishing jig required to polish the flat end face at an 8-degree angle?

No. You can use the same polishing jig as for MT Ferrule that are polished at an 8-degree pre-angle. Polishing conditions can be shared. (For measurements at the Ishikawa plant, we use Domaille, and at the development center, we also use SEIKOH GIKEN/NTT-AT. You can also inquire with the respective polishing machine manufacturers.)

If you polish from a flat surface to an 8-degree angle, wouldn't the increased amount of material removal cause misalignment of the hole position and result in variations in accuracy?

The product is designed to be in the correct position after polishing, and we inspect sampled products from the shipping lot for the fiber hole position and fiber angle after polishing, so there are no problems with the accuracy.

What equipment do you use to observe the end face shape?

Data-Pixel(D-Scope/Daisi MT）

MTCOMPACT

Do I need special polishing jigs or measuring jigs for end face observation?

Special equipment is required, and Domaille/SEIKOH GIKEN/NTT-AT can accommodate this.
After the NDA is signed, we will be able to provide you with the specific part number of the polishing jig.
A special measuring jig is also required. Data-pixel/DORC can accommodate this. (Sumix does not.) If there is a customer request, we can also work with Sumix.

What are the polishing conditions?

The polishing conditions for Slim & Short and Slim are different. Short can be polished under the same polishing conditions as regular MT Ferrule.

How do I connect MTCOMPACT series?

Slim: Clip connection only (usually uses ferrule clip and guide pin)
Short: Clip connection (dedicated clip and dedicated guide pin) or connection via MT-MPO adapter
Slim & Short: Clip connection (dedicated clip and dedicated guide pin) or MTCT connector connection
