## Summary description

The EFB Elektronik O2003.1 is a 1 m OS2 fibre optic cable featuring ST connectors on both ends. With a core diameter of 9 µm, it supports full duplex communication, ensuring high-speed data transfer and reliable connectivity for InfiniBand applications. Its yellow color aids in easy identification in complex setups.

## Long description

The EFB Elektronik O2003.1 1 m ST Yellow is a single-mode OS2 fibre optic patch cable designed for point-to-point links and equipment interconnects. With ST connectors on both ends and a 9 μm core diameter, the cable supports full-duplex data transmission and is intended for high-speed, low-loss optical connections. The yellow jacket provides clear visual identification in cabling systems and helps separate single-mode runs from multimode infrastructure.
Advantages
This fibre optic cable delivers low attenuation and consistent transmission characteristics suitable for long-distance single-mode links. The ST connectors provide secure bayonet-style mating for rack-mounted equipment and networking panels. Its short 1 m length reduces excess slack and maintains tidy cable management in dense server rooms or instrument racks. The OS2 single-mode specification ensures compatibility with common telecom and datacom transceivers used in InfiniBand and other high-speed environments.
Suitable for
 Direct equipment-to-equipment connections in data centers and laboratories
 InfiniBand interconnects and other high-speed optical links
 Patching between optical panels and transceivers with ST interfaces
 Short in-rack or console connections where a 1 m fibre is sufficient
Key specifications
 Fibre type: single-mode OS2
 Core diameter: 9 µm
 Connector type: ST to ST (bayonet-style)
 Length: 1 m
 Colour: yellow jacket for single-mode identification
 Transmission: full duplex optical link
How to use
Inspect connector endfaces before installation and, if possible, clean them with an appropriate fibre cleaning tool to prevent signal loss. Align each ST connector with the corresponding port and insert with a slight push and a twist to engage the bayonet locking mechanism. Use gentle handling to avoid sharp bends; maintain a bending radius recommended for single-mode fibre to preserve performance. Route the cable along cable trays or within racks to avoid strain and secure it with suitable clips or ties without compressing the jacket.
Usage recommendations
For optimal performance, store and install the cable in a clean environment, avoid repeated mating cycles without inspection, and follow standard single-mode fibre handling practices. Choose this 1 m ST patch cable where short, low-loss single-mode connections are required, and match connector types and fibre specifications with existing equipment to ensure compatibility.
