Fibre optic cable DELOCK 80159 OS2 50 m 2x LC → 2x LC, 9 µm, full duplex, yellow/blue

DELOCK 80159 is a 50 m single‑mode fibre optic cable (OS2) with 2x LC connectors on each end and a 9 µm core diameter designed for full duplex transmission. The cable supports high‑speed optical links for fibre networks, InfiniBand interconnects and long‑reach connections in server rooms and data centres. The jacket is halogen‑free (LS0H/LSZH) and the product is supplied in yellow and blue colours for clear identification of fibre legs.

Advantages

This DELOCK fibre optic cable offers low insertion loss (typically < 0.15 dB) and high return loss (> 55 dB), enabling reliable signal integrity over long distances. The 9/125 µm single‑mode fibre (OS2) and ceramic ferrules ensure stable mating and minimal attenuation. With a small cable diameter and a minimum bending radius of 25 mm, the cable is easy to route in constrained installations while maintaining performance. The LSZH jacket reduces toxic gas and smoke in case of fire, making it suitable for indoor installations.

Suitable for

• Connecting switches, transceivers and media converters in data centres
• Long‑reach single‑mode links between equipment racks or buildings
• InfiniBand and high‑speed optical interconnects requiring full duplex transmission
• Indoor installations where halogen‑free cabling is required

How to use

Inspect connector endfaces and remove protective dust caps before insertion. Route the cable to avoid sharp bends and maintain the specified minimum bending radius of 25 mm. Insert LC connectors into compatible LC ports on switches, media converters or transceivers, ensuring correct duplex orientation. Secure the cable along trays or racks using appropriate cable management to prevent strain on the connectors and avoid kinking the fibre.

Recommendations

For best performance, keep connector endfaces clean and use an inspection microscope or cleaning tools when necessary. Avoid tight bends and excessive pulling force on the cable during installation. Use the yellow and blue colour coding to maintain consistent labelling of transmit and receive legs, and store spare length coiled with a gentle radius to preserve fibre integrity.
