## Long description

The EFB Elektronik O2003.2 2 m ST Yellow is a single‑mode OS2 fibre optic patch cable designed for reliable point‑to‑point connections. With ST connectors on both ends and a 9 µm core diameter, this 2 metre cable supports full‑duplex transmission and is intended for use in structured cabling, telecommunications and data centre links where low attenuation and consistent signal integrity are required. The yellow jacket provides common colour coding for single‑mode installations and aids identification in multi‑cable environments.
Advantages
This fibre cable offers low insertion loss and stable optical performance due to its single‑mode OS2 design and 9 µm core. The ST connectors provide a bayonet coupling that is widely used in networking equipment and patchpanels, allowing secure and repeatable connections. The 2 m length balances flexibility and signal management for short to medium interconnects, while the yellow sheath simplifies visual organisation in racks and cabinets.

Key specifications
Fibre type: single‑mode OS2
Core diameter: 9 µm
Connector type: ST on both ends
Length: 2 m
Transmission: full‑duplex
Jacket colour: yellow (single‑mode colour code)
How to use
Inspect connector endfaces for dust or contamination before insertion to avoid increased attenuation. Align the ST connector with the mating adapter and push with a slight twist until the bayonet locks. Use appropriate cable management to avoid tight bends; maintain the manufacturer’s recommended minimum bend radius for single‑mode fibre to preserve optical performance. For removal, depress the bayonet release and pull straight out without twisting the cable sharply.
Usage recommendations
Store and handle the cable in a clean environment to prevent contamination. Regularly clean connector endfaces with approved fibre cleaning tools when reconnecting. Avoid kinking or exposing the cable to excessive tensile force and observe minimum bend radius guidelines to ensure long‑term signal quality.
