## Long description

The BlueOptics SFP9131BU2MK is a high-performance 2-meter OS2 singlemode fibre optic patch cable designed for reliable, high-speed data transmission. Featuring a CS connector on one end and an LC connector on the other, this duplex cable utilizes a 9 µm core diameter to ensure optimal signal integrity. Built with premium components and a durable, flame-retardant LSZH jacket, it is engineered to meet rigorous networking standards for professional environments.
Advantages
This patch cable offers exceptional signal quality with low insertion loss and high return loss, ensuring stable data transmission over long distances. The use of high-quality ceramic ferrules and branded fibres guarantees a long service life of up to 1500 mating cycles. Furthermore, the LSZH jacket provides enhanced safety by minimizing smoke emission and eliminating halogen release in the event of a fire, making it compliant with strict international safety and environmental standards.
Suitable for
Connecting optical transceivers in data centers
Linking patch panel ports in enterprise networks
High-speed telecommunications infrastructure
Professional environments requiring reliable OS2 singlemode connectivity
This cable is not suitable for multimode networking environments, as it is specifically designed for singlemode OS2 applications. Additionally, it should not be used in environments where the required cable length exceeds 2 meters or where the specific CS to LC connector interface is not supported by the existing hardware.
Key specifications
Cable length: 2 m
Fibre type: OS2 Singlemode (E9/125µm)
Connector 1: CS (UPC polish)
Connector 2: LC (UPC polish)
Jacket material: Low Smoke Zero Halogen (LSZH)
Core diameter: 9 µm
Duplex configuration
Operating wavelengths: 1310nm / 1550nm
To use the cable, carefully remove the protective dust caps from the connectors immediately before installation to prevent contamination of the fibre end-faces. Insert the CS and LC connectors into the corresponding ports on your networking equipment until you hear a secure click. Ensure the cable is routed with appropriate bend radii to maintain signal integrity and avoid physical stress on the connectors.
What to consider before purchase
Verify that your networking hardware supports CS and LC connector interfaces.
Ensure the 2-meter length is sufficient for your specific cable management needs.
Confirm that your equipment is compatible with OS2 singlemode fibre specifications.
Usage recommendations: Always inspect and clean the fibre optic connectors with appropriate cleaning tools before each connection to ensure optimal performance. Keep the included measurement protocol for your records to verify the cable's factory-tested attenuation values.
