Optical connector polishing machine POP311 product image
Optical connector installation work for detached houses and broadband compatible condominiums associated with FTTH. Excess length processing optical connector installation work associated with optical fiber laying in intelligent buildings, or regrinding of damage repair of already laid optical fiber connector end faces. These can be worked on site.
It can also be used as the world's first manual MT polishing machine by using the attachment for MT (sold separately).

You can watch a video of the polishing work that anyone can easily do.


battery powered

Easy-to-find rechargeable Ni-MH batteries (AA) and alkaline batteries (AA) can be used.

high speed polishing

Polishes optical connectors at a high speed rotation of 700 times per minute. Moreover, it can be easily done on site in 3-5 processes.
Adhesive removal ~ AdPC polishing ⇒ 150 seconds (SC connector/terminal)
AdPC polishing by regrinding ⇒ 50 seconds (SC connector/terminal)
(AdPC Polishing: Advanced PC Polishing)

high quality polishing

Generous use of technology cultivated in mass-production polishing machines at factories. Polishing quality is the same level as for factory use.

Features of exchangeable attachment jigs

Since the attachment is shared with the factory polishing machine ATP-3000, it can handle a wide range of polishing such as polishing of MPO connectors, single-core connectors (UPC/APC), various capillaries and fibers only.

MT connector polishing process (ferrule: 12MT-PPS-SM)

Process name Used film Time

Abrasive properties

Abrasive properties
RX(mm) >2000, RY(mm) >5,
