Types of optical fiber and application areas

Precautions for handling

We take the utmost care in the manufacture and quality control of optical cables; however, optical fibers are made of extremely thin quartz glass. To ensure maximum performance, please handle them properly.

Transportation, packaging

When transporting the product, protect it with cushioning material or similar to avoid strong impact or external force. Otherwise, the optical fiber may break. When handling the packaging box, follow the handling instructions indicated by the care marks printed on the box.
If the product is exposed to water or left for a long period in an extremely high-humidity environment, its optical characteristics may be affected. If such a situation may occur, seal the product securely in a poly bag or similar, and store and protect it with a desiccant.
When storing the product, store and manage it in accordance with the storage conditions specified for each product.
Using a cutter knife when taking the product out of the bag or untying a cable bundle may damage the product. Open the package with sufficient care.

Installation, mounting

When installing the cable, use the correct installation method according to the cable structure. For products with a tensile member for installation at the center of the cable, pull the cable by that tensile member. For cables without a central tensile member, pull the cable by gripping the entire cable with a cable grip or similar tool. In either case, if the product has an optical connector at the end, be sure to protect the optical connector securely and take care to prevent bending or external force from being applied. Never pull the cable by gripping the connector.
When routing the cable through narrow conduit or similar spaces, take sufficient care not to bend the cable below the minimum installation bending radius specified for each product.
During work in rainy weather or similar conditions, take care to prevent water from entering the cable.
After installation, when removing protective materials used to protect the cable, take care not to damage the product with a cutter knife or other blade.
When paying out a coiled cable, use a dedicated cable pay-off device, or lay the cable in a figure-eight pattern, to prevent the cable from twisting. Twisting may cause the optical fiber to break.
When mounting and fixing the optical cable, do not overtighten it with cable ties, cable clamps, or similar. When fixing the optical cable in a bent position, be sure to observe the minimum bending radius specified for each product.
After installation, when storing excess cable length, store it in as large a circular loop as possible.
When holding and fixing thin optical cords with clamp parts, use clamp parts dedicated for optical fibers that include cushioning material.

Installation in equipment

When attaching an optical plug connector to the mating device(optical module), clean the connector end face thoroughly with a dedicated cleaner before installation. If, by any chance, hard foreign matter that cannot be removed with a cleaner or similar is attached to the connector tip, do not force use; contact our consultation desk.
Check the insertion direction of the optical connector, and attach it after confirming that it mates smoothly without force.
When connecting or disconnecting an optical cable while the equipment is operating, strong light may be emitted from the optical fiber end face and the equipment-side optical module. Do not look directly with the naked eye. In the worst case, this may cause blindness.
Be sure to insert the optical connector firmly until it locks. If the lock is incomplete, it may come off during use.

Disposal

When disposing of optical cables and optical-related products, do not forcibly disassemble or incinerate them; dispose of them as general industrial waste. Forcibly disassembling them may cause extremely thin glass fragments to pierce the body.
For details, dispose of them in accordance with instructions from the relevant local authorities.
