## Long description

EFB Elektronik O0383.3 is a 3 m single-mode fibre optic patch cable designed for OS2 networks. It features an LC connector on one end and an SC connector on the other, a 9 µm core diameter and supports full duplex transmission. The cable is intended for high-speed optical links and network interconnects in environments such as server rooms, data closets and telecom racks where stable single-mode connectivity is required.
Advantages
The cable combines LC and SC terminations to provide compatibility with a wide range of networking equipment while preserving single-mode performance. With a 9 µm core and OS2 specification, it offers low attenuation suitable for longer runs within campus and data centre environments. Full duplex support enables simultaneous bidirectional data transfer over paired fibres, reducing latency for point-to-point links. The yellow jacket identifies the cable as single-mode, helping with cable management and rapid identification in bundled installations.
Suitable for
 Connecting servers, switches and optical transceivers with LC and SC ports
 Single-mode backbone links in data centres and telecom rooms
 Point-to-point links requiring full duplex optical transmission
 Patch panels and cross-connects where LC-to-SC adapters are not available
Key specifications
 Fiber type: single-mode (OS2)
 Length: 3 m
 Connectors: LC to SC
 Core diameter: 9 µm
 Transmission: full duplex (paired fibres)
 Jacket colour: yellow
How to use
Inspect connector endfaces for dust or contamination before insertion. Align the LC connector with the LC port and insert until it clicks; align the SC connector with the SC adapter or port and push until secure. Use appropriate cable management to avoid tight bends; maintain the manufacturer’s minimum bend radius for single-mode fibre. For removal, depress the LC latch and pull straight out for both LC and SC connectors to avoid stress on the ferrule.
Usage recommendations
Keep connector endfaces covered with dust caps when not in use, clean with approved fibre cleaning tools if performance degrades, and avoid bending the cable sharply. Match the cable type (OS2 single-mode) to your transceiver and link budget requirements to ensure expected optical performance.
