Product information

Description

The BlueOptics SFP2121BU5MS is a high-quality 5-meter singlemode OS2 fibre optic patch cable designed for reliable and efficient data transmission in professional networking environments. Featuring LC-UPC to LC-APC connectors, this cable utilizes premium G.657.A1 fibre with a 9 µm core to ensure minimal signal attenuation and high signal integrity. The yellow LSZH (Low Smoke Zero Halogen) jacket provides both durability and safety, making it an essential component for modern fibre optic infrastructures.

Advantages

This patch cable offers exceptional performance due to its high-grade ceramic ferrules and precise manufacturing standards. The use of G.657.A1 fibre allows for tighter bend radii without compromising signal quality, which is beneficial in dense cabling environments. Furthermore, the inclusion of a measurement protocol ensures that each cable meets strict insertion loss requirements, providing peace of mind for critical network deployments. The LSZH material enhances safety by reducing toxic smoke emissions in the event of fire.

Suitable for

  • High-speed data centre interconnects
  • Enterprise local area networks
  • Telecommunications infrastructure
  • Fibre-to-the-Home (FTTH) installations
  • Professional server room cabling

This cable may not be suitable for outdoor environments where it is directly exposed to harsh weather conditions, UV radiation, or mechanical stress without additional protective conduit. It is also not intended for use with multimode networking equipment, as it is strictly designed for singlemode OS2 applications.

Key specifications

  • Length: 5 m
  • Fibre type: Singlemode OS2 (G.657.A1)
  • Core diameter: 9 µm
  • Connector types: LC-UPC to LC-APC
  • Jacket material: LSZH (Low Smoke Zero Halogen)
  • Colour: Yellow
  • Insertion loss: Less than 0.2 dB

How to use

To use the cable, carefully remove the protective dust caps from the LC connectors. Ensure that both the connector tips and the ports on your networking hardware are clean and free of dust or debris. Gently insert the connector into the corresponding port until you hear a soft click, indicating a secure connection. Avoid pulling the cable tightly or bending it beyond its recommended radius to maintain optimal performance.

What to consider before purchase

  • Verify the connector type required by your hardware (LC-UPC/APC compatibility).
  • Ensure the 5-meter length is sufficient for your specific cable path.
  • Confirm that your networking equipment supports singlemode OS2 fibre.
  • Check if your installation environment requires LSZH-rated cabling for fire safety compliance.

Usage recommendations

Always inspect and clean fibre optic connectors with appropriate cleaning tools before every connection to prevent signal degradation caused by contamination.
