High-Precision ST Multimode Fiber Connector for Optical Networks

The D-Link ST Multimode Fiber Connector (NCO-FMSST09) is designed to deliver reliable, low-loss fiber termination for professional optical networking environments. It is widely used in telecommunication networks, LAN and data communication systems, and optical equipment installations. Moreover, the ST connector’s bayonet-style locking mechanism ensures secure connections, even in environments with vibration or frequent handling.

Multimode ST Connector for Stable Data Transmission

This connector supports multimode fiber (MM) and is suitable for short- to medium-distance optical links. As a result, it is commonly used in enterprise networks, campus backbones, and data centers. In addition, the ST interface allows quick and easy installation, making it a preferred choice for field terminations and maintenance tasks.

High-Precision Ceramic Ferrule for Low Insertion Loss

A key feature of the D-Link ST Multimode Fiber Connector is its 2.5mm high-precision ceramic ferrule. This ferrule ensures accurate fiber core alignment and helps maintain insertion loss below 0.3 dB, as specified in the datasheet. Therefore, signal quality remains stable and consistent across connections. Furthermore, the ceramic ferrule maintains alignment accuracy even after repeated mating cycles.

Nickel-Plated Brass Housing for Durability

The connector uses a high-precision nickel-plated brass housing, which provides excellent mechanical strength and corrosion resistance. Consequently, it performs reliably in demanding environments such as telecom rooms and industrial installations. This robust housing also enhances the connector’s lifespan.

Strain Relief Boots for Fiber Protection

The connector is supplied with 900µm and 3mm strain relief boots, which protect the fiber from bending stress and mechanical damage. As a result, it is well suited for use with pigtail and buffered fiber cables, ensuring long-term reliability.

Standards Compliance and Long Service Life

The NCO-FMSST09 ST connector complies with IEC61754-20, IEC61300-2-2, and IEC61753-1 standards, ensuring compatibility and performance consistency. It also supports up to 1000 mating cycles and operates in temperatures from –40°C to +85°C, making it suitable for harsh environments
