## Summary description

EFB Elektronik O1403.3 is a 3 m fibre optic patch cable for singlemode OS2 networks. It features LC to LC connectors and a 9 µm core diameter, suitable for high-speed data transmission and long-distance links. The yellow jacket identifies singlemode fibre and the cable is intended for network interconnects, patch panels and optical equipment connections.

## Long description

EFB Elektronik O1403.3 is a 3 m singlemode fibre optic patch cable designed for OS2 networks. The cable has LC to LC connectors and a 9 μm core diameter, providing a standardized singlemode interface for optical links. Its yellow jacket indicates singlemode fibre and the flexible construction makes it suitable for interconnects between patch panels, active equipment and optical transceivers in telecommunications and data centre environments.
Advantages
The LC–LC connector pair ensures compact duplex connections with low insertion loss and reliable mating to common singlemode ports. A 9 μm core diameter and OS2 specification offer low attenuation for long-distance links and stable optical performance. The 3 m length provides sufficient reach for rack-to-rack and equipment-to-patch-panel connections while remaining manageable in cable trays and underfloor ducts.
Suitable for
 Interconnecting patch panels and switches in data centres
 Connecting optical transceivers to network equipment
 Telecommunications backbone links and long-reach singlemode runs
 Laboratory, testbench and equipment connectivity for singlemode systems
Key specifications
 Fibre type: singlemode, OS2
 Connector type: LC–LC duplex
 Length: 3 m
 Core diameter: 9 μm
 Jacket colour: yellow (singlemode identification)
 Typical use: patch cable for optical interconnects
How to use
Route the cable between the two devices ensuring minimal bending and avoiding sharp kinks; maintain the manufacturer’s recommended minimum bend radius for singlemode fibre. Clean the LC connector endfaces with appropriate fibre cleaning tools before mating to prevent signal loss and connector damage. Insert each LC connector firmly into the corresponding duplex port until it clicks; secure any cable management clips or ties to avoid tension on the connectors. When disconnecting, depress the LC latch and pull straight out without twisting.
Usage recommendations
Store and handle the cable in a dry, dust-free environment. Use dust caps when connectors are not in use, avoid exposing the cable to temperatures or mechanical stress beyond the device specifications, and perform visual inspection and endface cleaning periodically to maintain optimal optical performance.
