Fiber Optic Adapter

The Flame Retardant Grade of the Adapter

The flammability UL94 is the most widely used flammability standard for plastic materials. It is used to evaluate the extinguishing ability of the material after being ignited. According to the burning speed, burning time and anti-drip ability, there are many ways to judge the extinguishing ability. HB, V0, V1, V2 are different flame retardant grades, because their grades are different, the flame resistance test method is also different, and the test judgment standard is also different. The flame retardant grades are gradually increased from HB, V-2, V-1 to V-0.

Insertion Loss

The insertion loss is generally required to be less than 0.2 dB. If the insertion loss is too high, it will affect the optical transmission.

Durability

The fibre optic cable adapter needs to be plugged and unplugged frequently during use, so the durability of the adapter should be high. The normal standard requires that the number of plugging and unplugging can reach more than 500 times without affecting the performance.

Working Temperature

-40℃~75℃ is the normal working temperature range of the FC to ST adapter.

The Material of the Fiber Optic Adapter Alignment Sleeve

The alignment sleeve is the most important part of the optical fiber adapter. Generally, metal or ceramic materials are used. The optical fiber adapter made of ceramic will have a relatively good effect. Because the crystal structure of the ceramic is hard and it is not easy to deform, it can achieve rapid alignment and high precision fiber end-to-face connection.

Others

When choosing a fiber optic adapter, you can select relatively high-quality and stable fiber optic adapters through the above important factors. Of course, you also need to consider other factors that affect quality, such as tensile strength and compliance standards. Fiber optic adapters are widely used in communication room, FTTH fiber to the home, local area network, fiber optic communication system, fiber optic connection transmission equipment, national defense combat readiness, etc. Although the optical fiber adapter is small, its quality directly affects the entire optical fiber link. Therefore, the selection of the fiber optic adapter should be rigorous and comprehensive.

Step 1: Inspect the fiber optic connector, component, or bulkhead with a fiberscope.

Step 2: If the connector is dirty, clean it with a dry cleaning technique.

Dry cleaning: Using a reel-based cassette cleaner with medium pressure, wipe the connector end face against a dry cleaning cloth (single swipe per exposure) in one direction. For angled physical contact (APC) polished connectors, ensure that the entire end face surface mates with the cleaning cloth. Dry cleaning will generally remove airborne contamination and should be attempted first. Inspect the connector end face for contamination after cleaning.

Step 3: Inspect the connector.

Step 4: If the connector is still dirty, repeat the dry cleaning technique.

Step 5: Inspect the connector.

Step 6: If the connector is still dirty, clean it with a wet cleaning technique followed immediately with a dry cleaning in order to ensure no residue is left on the end face.

Wet cleaning: Lightly moisten a portion of a lint free wipe with fiber optic cleaning solution (or > 91% Isopropyl Alcohol) and applying medium pressure, first wipe the end face against the wet area and then onto a dry area to clean potential residue from the end face. For APC polished connectors, ensure that the entire end face surface mates with the cleaning wipes. Wet cleaning is more aggressive than dry cleaning, and will remove airborne contamination as well as light oil residue and films.

Step 7: Inspect the connector again.

Step 8: If the contaminate still cannot be removed, repeat the cleaning procedure until the end face is clean.

Note: Never use alcohol or wet cleaning without a way to ensure that it does not leave residue on the end face. Or it will cause equipment damage.
