## Long description

The BlueOptics SFP2121BU20MS is a high-performance singlemode fibre optic patch cable measuring 20 meters in length. Designed for demanding network environments, this cable utilizes G.657.A1 fibre technology to ensure superior signal integrity and minimal data loss. It features LC to LC connectors with high-quality ceramic ferrules, providing a reliable and stable connection for professional telecommunications and data center infrastructure.
Advantages
This patch cable offers exceptional durability and performance due to its LSZH (Low Smoke Zero Halogen) jacket, which enhances safety in enclosed spaces by reducing toxic emissions in the event of fire. The use of premium-grade fibre ensures low insertion loss, making it an ideal choice for long-distance data transmission where signal quality is critical. Its flexible design and robust construction facilitate easy installation in dense cabling environments while maintaining high mechanical resistance.
Suitable for
High-speed telecommunications networks
Data center interconnects
Enterprise-level fibre optic cabling
Long-range signal transmission
When it may not be suitable
This cable is designed specifically for singlemode applications and will not function in multimode fibre optic systems. It is not intended for outdoor use without additional protective conduit, as the standard jacket is optimized for indoor environments.
Key specifications
Length: 20 meters
Fibre type: Singlemode OS2 (G.657.A1)
Connectors: LC to LC
Jacket material: LSZH
Core diameter: 9 µm
Colour: Yellow
How to use
To install the cable, carefully remove the protective dust caps from the LC connectors. Align the connector with the corresponding port on your networking equipment and insert it until you hear a distinct click, indicating that the latch is engaged. Ensure that the cable is not bent beyond its minimum bend radius to prevent signal degradation. After connection, verify the link status on your network hardware to confirm successful data transmission.
What to consider before purchase
Verify that your networking equipment supports LC interface connections.
Ensure that your system requires singlemode (OS2) fibre rather than multimode.
Check the required cable length to ensure 20 meters is sufficient for your installation path.
Usage recommendations: Always clean the fibre optic connector tips with an approved cleaning tool before insertion to prevent dust contamination, which can significantly impact signal performance.
