## Summary description

The EFB Elektronik O2003.050 is a 0.5 m OS2 fibre optic cable with ST connectors on both ends. It features a 9 µm core diameter and supports full duplex communication, ensuring high-speed data transmission. Ideal for reliable networking and data center applications.

## Long description

The EFB Elektronik O2003.050 is a 0.5 m single-mode OS2 fibre optic cable fitted with ST connectors on both ends and a 9 µm core diameter. Designed for short interconnects in structured cabling and equipment links, the cable supports full duplex transmission and is suitable for use in networking, telecommunications and data centre environments where low attenuation and reliable signal integrity are required.
Advantages
This OS2 fibre cable delivers low loss and stable optical performance over single-mode links, ensuring consistent high-speed data transfer. Its ST connector terminations provide secure, easy mating with legacy and commercial networking equipment that use bayonet-style fibre connectors. The short 0.5 m length reduces excess slack in rack and patch panel installations and helps maintain neat cable management while minimising reflection and insertion losses associated with longer jumper cables.
Suitable for
 Connecting transceivers and fibre ports between network devices in racks
 Patch panels and short-distance interconnects inside data centres
 Telecommunications equipment requiring single-mode ST-terminated links
 Lab or bench testing where a reliable short fiber jumper is needed
Key specifications
 Fibre type: single-mode (OS2)
 Core diameter: 9 µm
 Length: 0.5 m
 Connector type: ST on both ends
 Transmission mode: full duplex
 Typical use: patch cord / jumper for optical links
How to use
Inspect connectors and cable jacket for any visible damage before installation. Align the ST connector bayonet key with the equipment receptacle, insert and twist to lock the connector in place. Use one fibre per direction to establish full duplex communication. Route the cable with gentle bends to avoid exceeding the minimum bend radius and secure it within the rack or panel to prevent strain on the connectors. When disconnecting, twist and pull the ST connector straight out without forcing.
Usage recommendations
Store the cable with protective caps on connectors when not in use, and clean connector endfaces with approved fibre cleaning tools before mating to maintain low insertion loss. Avoid tight bends and unnecessary mechanical stress; for installations requiring longer runs or outdoor exposure, select appropriate outdoor-rated or multi-mode variants as needed.
