Fibre optic cable EFB Elektronik O1403.3, OS2 singlemode, LC–LC connectors, 3 m, 9 µm core, yellow

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.
