PDLC stands for Pushable Durable LC connector, also known as Outdoor PDLC or sometimes called a “Mini SC” style outdoor waterproof connector. It utilizes a standard LC (Lucent Connector) duplex as its internal interface, but adds a ruggedized, waterproof, and dustproof shell for outdoor environments. PDLC connectors are most common in FTTA (Fiber to the Antenna), outdoor base station, and harsh environment fiber deployments. They’re well-known for their use with Ericsson RRUs (Remote Radio Units) but are also used by Huawei and other telecom equipment.PDLC Fiber Optic Connector is the one of adding waterproof housing over the LC duplex connector. It’s stable, waterproof and dust-proof.It’s mostly used in FTTA and any other outdoor waterproof fiber optic connection.

IDC Fiber Optic Connector is connected to each other by metal screw thread with female and male types, adapter is not needed. It’s stable, and water& dust proof. 2cores, 4cores and MT multi-cores are optional. It’s mostly used in outdoor harsh environment of FTTA, well, sensing, electric power.

FLX Fiber Optic Connector can be used in providing SFP connections between Radio Remote Unit(RRU) and Building Base Band Unit (BBU). It’s compatible with various types of SFP converter, and it allows end users to choose converters to meet requirement of system.

NSN Fiber Optic Connector refer to a type of rugged, outdoor waterproof fiber optic connector widely used in telecom, especially for FTTA (Fiber to the Antenna) and harsh environment applications. NSN connectors are typically designed to be compatible with Nokia (formerly NSN – Nokia Siemens Networks) base station hardware, which is where the name comes from.,This is corrugated waterproof square rubber boot, with LC duplex connector built-in. it can be customized for other connectors like RJ45, MPO etc. It’s mainly used in terminal systems of Nokia Siemens. It’s flexible and dust proof.

ODVA fiber optic connector is a ruggedized connection interface designed specifically for industrial and harsh outdoor environments. “ODVA” actually refers to the Open DeviceNet Vendors Association, which developed a standard for robust, waterproof connections suitable for field-deployed fiber optic networks. The ODVA interface provides a robust, waterproof, and dust proof connection, mainly used in industrial, outdoor, and FTTx (Fiber to the x) applications.

OPT Fiber Optic Connector is a ruggedized, waterproof connector system that integrates standard indoor connectors (such as SC, DLC, and MPO) into a durable, sealed housing designed for reliability in both indoor and outdoor environments. Its screw-thread connection combined with rubber washers ensures an IP67-rated waterproof seal, making it suitable for harsh conditions.OPTH Floating Socket is a part of the OPT series ruggedized, waterproof fiber optic connectors. It is specifically designed to provide flexible, secure, and reliable connections—especially for outdoor or industrial environments where misalignment, vibration, and harsh conditions are factors.

Rosenberger is a global leader specializing in advanced connectivity solutions, and Rosenberger outdoor fiber optic connectors are engineered for use in harsh environments such as telecommunications, industrial, and FTTA (Fiber to the Antenna) networks.

Jonhon (JONHON Electronics) is a trusted manufacturer of ruggedized and high-performance fiber optic connectivity solutions, especially for outdoor and industrial applications. Their outdoor fiber optic connectors are widely used in telecommunications, military, aerospace, industrial automation, FTTA (Fiber to the Antenna), and other harsh environments requiring durable, waterproof connections.
Here is a comprehensive comparison table of the most common outdoor/waterproof fiber optic connector types and series—including the ones you listed and a few more. This will help you identify the differences in design, applications, compatibility, and core features.
