As technology continues to advance, FTTH (Fiber-to-the-Home) access network technology is also constantly evolving. The pre-connectorized connector, as a new-generation passive device solution, has attracted widespread attention. It provides high scalability and flexibility, low insertion loss and cost, and dust/waterproof protection. This article will take you through the main pre-connectorized connector.
What is a Pre-Connectorized Connector?
The pre-connectorized connector is a passive device to terminates the end of optical fiber and enables quicker connection and disconnection than fiber splicing. It is factory-terminated and tested, ensuring a guaranteed level of quality. The fiber connection is a simple plug-and-play mechanism, eliminating the need for splicing throughout the process. The pre-connectorized connector is designed for FTTH, FTTA, and indoor and outdoor environments. It enhances the stability and reliability of optical links and reduces installation time and cost.
Types of Pre-Connectorized Connectors
1) Type B Pre-Connectorized Connector
Type B pre-connectorized connector adopts a screw and bayonet locking mechanism. It is compatible with a standard SC field install connector(FIC)/ fast connector or patch cord with a standard SC connector. In addition, it is suitable for a 2*3mm/4*7mm flat drop cable or a 5.0mm round cable.
2) Type C Pre-Connectorized Connector
Type C pre-connectorized connector adopts an external buckle locking mechanism: the outer shell of type C is connected with the buckle on the type C adapter. It is suitable for a 2*3mm drop cable or 5.0mm round cable and is compatible with a type C adapter. Thus, its structure allows greater security and protection against external mechanical and the environment.
3) Type D Pre-Connectorized Connector
Type D pre-connectorized connector uses a bayonet locking mechanism for field assembly. It is suitable for a 2*3mm drop cable or 5.0mm round cable and is compatible with a type D adapter. Thus, its structure allows greater security, protection against external agents, and tensile strength.
4) Type J Pre-Connectorized Connector
Type J pre-connectorized connector adopts an internal buckle locking mechanism: type J connector is connected with the buckle inside the type J adapter. It is suitable for a 2*3mm drop cable or 5.0mm round cable and is compatible with most adapters. Its structure allows greater security, protection against external agents, and tensile strength.
5) Type K Pre-Connectorized Connector
Type K pre-connectorized connector uses a thread locking mechanism: Only need to screw 1 round (360°) to lock the connector and adapter. It adopts a patented rotary compression sealing structure and has a low risk of sealing failure. Additionally, it is suitable for a 2*3mm drop cable or 5.0mm round cable and is compatible with a type K adapter.
What is IP68?
IP is the short abbreviation for Ingress Protection. The International Electrical Commission (IEC) defines the IP rating as international standard IEC 60529. To evaluate the anti-solid and waterproof enclosure performance, focus on the two digits XX at the end of IPXX. The ' 6' in IP68 indicates that there is no ingress of the duct. The '8' in IP68 denotes that the enclosure can withstand continuous immersion in water without allowing harmful water ingress.
Features and Benefits
The pre-connectorized connector provides the following features and benefits:
1. Low insertion loss and cost
2. High return loss and durability
3. High stability, flexibility, and reliability
4. Field assembly and factory terminated and tested
5. Easy installation and small size
6. Protection rating IP65/IP68
7. Available with SC/UPC or SC/APC connectors
Applications
The pre-connectorized connector is used in FTTH access networks, telecommunication networks, CATV networks, local area networks (LAN), fiber optic patch cords, pigtails, fiber optic distribution boxes, FTTA, 5G, etc.
Conclusion
The pre-connectorized connector can provide low-cost and easy installation in the FTTH access network field. It provides IP65/IP68-rated water and dust resistance to ensure the reliability of fiber connections in severe weather conditions.
