## Summary description

The EFB Elektronik O2561.3 is a 3m OS2 fibre optic cable featuring 2x SC connectors on both ends. With a core diameter of 9 µm, it supports full duplex communication, ensuring high-speed data transfer and reliable performance. The yellow color coding helps in easy identification and organization of cables in networking setups.

## Long description

The EFB Elektronik O2561.3 is a 3 m OS2 singlemode fibre optic patch cable with SC connectors on both ends in a duplex configuration. The cable uses a 9 µm core diameter suitable for long-distance singlemode transmission and provides stable, low-loss connections for network equipment that requires SC-to-SC terminations. The yellow jacket aids visual identification and cable management in patch panels and structured cabling installations.
Advantages
This fibre optic cable offers low attenuation and consistent optical performance appropriate for singlemode networks. The duplex SC connector arrangement supports full duplex data transmission and simplifies pairing of transmit and receive channels. The standardized connector form factor ensures compatibility with equipment that uses SC ports, while the 3 m length balances reach and tidy patching in racks and telecom cabinets.
Suitable for
 FTTx and backbone singlemode links in enterprise or data centre environments
 Patching between switches, optical transceivers and patch panels with SC ports
 Structured cabling where consistent colour coding and duplex connections are required
 Laboratory or test setups requiring reliable short-reach singlemode interconnects
Key specifications
 Length: 3 m
 Fibre type: OS2 singlemode
 Core diameter: 9 µm
 Connector type: 2x SC on each end (duplex)
 Jacket colour: Yellow
 Transmission mode: Full duplex
How to use
Route the cable between the two devices ensuring gentle bends and avoiding sharp kinks to maintain optical performance. Insert each SC connector into the corresponding SC port until it clicks or seats securely, observing correct Tx/Rx orientation for duplex links. Secure excess cable length using cable management accessories and avoid placing heavy objects on the cable or stressing the connectors. For installation inside racks or enclosures, follow standard fibre handling procedures to protect endfaces and maintain low insertion loss.
Usage recommendations
Inspect and clean connector endfaces before making connections, use appropriate bend radius limits (typically \>30 mm depending on cable construction), and store or route the cable away from sources of mechanical stress and strong electromagnetic interference. Use this cable where singlemode OS2 optical characteristics are required and where SC connectors are specified.
