Fibre optic cable EFB Elektronik O1403.15 — 15 m, G.657.A2 singlemode, LC to APC connectors, 9 µm core

EFB Elektronik O1403.15 is a 15 m singlemode fibre optic patch cable built with G.657.A2 fibres and a 9 µm core. The cable terminates with an LC connector at one end and an APC connector at the other, providing a low-back-reflection connection suitable for installations that require precise return-loss control. The jacket is available in blue, green or yellow to match common colour-coding schemes used in telecom and data centre environments.

Advantages

The G.657.A2 fibre specification ensures improved bend performance compared with older singlemode types, allowing reliable signal transmission in environments with tight routing. The 9 µm core maintains compatibility with standard singlemode equipment while the LC-to-APC termination combines a compact LC interface with an angled-polish APC to reduce back reflections. A 15 m length offers flexibility for patching between panels, active equipment and distribution points without excessive slack.

Suitable for

• Interconnecting optical transceivers and patch panels in data centres
• Telecommunication links requiring low return loss
• FTTx and premises cabling with limited bend radius
• Test setups and temporary patching where a 15 m reach is required

Key specifications

• Length: 15 m
• Fibre type: singlemode G.657.A2
• Core diameter: 9 µm
• Connectors: LC (one end) to APC (other end)
• Connector polish: angled (APC) to minimise back reflection
• Jacket colours available: blue, green, yellow

How to use

Route the cable along the chosen pathway, avoiding sharp bends or tight kinks and securing it with appropriate clips or cable management accessories. Insert the LC connector into the corresponding LC socket and the APC connector into the matching APC receptacle, ensuring correct keying and full seating. Verify signal continuity and return loss with appropriate test equipment before finalising installation. For repeated patching, handle connectors by their housings and keep endfaces clean to preserve optical performance.

Usage recommendations

Use dust caps when connectors are not in use and clean connector endfaces with approved fibre-optic cleaning tools prior to mating. Maintain bend radius greater than the minimum recommended for G.657.A2 to avoid increased attenuation, and match connector types (LC to LC, APC to APC) on equipment where specified to ensure optimal optical performance.
