TIPS for Fast Fiber Connector

June 22, 2021

 

1)What is Fast fiber connector:

Fast fiber connector is used for field-assembled optical fiber connector "without fusion splicing of pigtail". It is widely used in fiber to the home (FTTH) optical access networks and the environment which need fast and easy fiber optic connection. It is not only available for single-mode, but also for multimode fiber. The fast connector is suitable for different type of cables such as 900 microns, 2mm, 3 mm and 3.0*2.0mm drop cable type.

 

2)Type of Fast fiber connector:

 

Pre-polished Ferrule Fast Connector

Features

  • Pre-embedded fiber and pre-polished ceramic ferrule (PC/APC) ensures excellent optical performance
  • Matching oil (Same refractive index as fiber) used in the high precision core parts to ensure the high stability and reliability of the connector
  • ALL connectors tested for insertion loss and return loss before leaving the factory
  • easy to assemble
  • Over 98% splicing success rate for single time assemble, total splicing success rate more than 99%
  • More than 5 times for re-assembling
  • Life Span over 15 years   

Straight-through Fast connector

Ferrule in optical fiber straight-through fast connector have no reserved fiber, there is no splice point in V-Groove, fiber end can be checked when construction, and without intermittent points in it.

Features

 

  • Using straight -through structure. All-metal fiber clamp. High-temperature resistance & high humidity resistance
  • Ultra strong environmental adaptivity. Besides working in ordinary environments, fast connector can be quickly fixed and works stably at various severe environment (severe cold, dust, high-temperature, high humidity)
  • Few special installation tools, construction is simple and fast, high reliability, the follow-up maintenance is almost free after the installation
  • High rate of working connections, above 99%
  • Reusable

3) Similarity:

Only normal fiber preparation tools are required, such as fiber stripping tool, wipes and a fiber cleaver. No electrical power supply is needed.

 

4Difference

Dawnergy’s Pre-polished Ferrule fast connector: There is a pre-polished fiber inside the connector, after you strip the fiber, you could insert the fiber into the connector until it touch the pre-embedded fiber.

Straight-through fast connector: There is no pre-polished fiber inside the connector, after you strip the fiber, you could insert the fiber into the connector up to the connector face.
