## Long description

The BlueOptics SFP2121BU50MM is a high-performance 50-meter singlemode fiber patch cable designed for reliable data transmission in professional networking environments. Featuring LC connectors on both ends and adhering to the OS2 fiber standard, this cable ensures minimal signal loss and high bandwidth capacity for demanding applications. The durable yellow jacket provides easy identification and protection for the internal fiber strands, making it an essential component for structured cabling systems.
Advantages
This fiber optic cable offers exceptional signal integrity over long distances, which is critical for maintaining high-speed network performance. The use of high-quality LC connectors ensures a secure and precise fit in standard SFP transceivers and patch panels, reducing the risk of connection instability. Its OS2 specification makes it ideal for long-haul telecommunications and high-capacity data center links, providing a robust solution that minimizes attenuation and supports future-proof network expansion.
Suitable for
High-speed data center interconnections
Telecommunication network infrastructure
Enterprise-level fiber optic cabling
Long-distance signal transmission between network equipment
This cable may not be suitable for short-range indoor applications where multimode fiber is already established as the standard, or in environments where the cable will be subjected to extreme physical stress, sharp bends, or high-temperature conditions that exceed the manufacturer's specified operating limits.
Key specifications
Length: 50 meters
Fiber type: Singlemode OS2
Connector type: LC to LC
Jacket color: Yellow
Application: High-speed data transmission
To use the BlueOptics fiber cable, carefully remove the protective dust caps from the LC connectors before insertion. Align the connector with the port on your networking hardware, such as an SFP module or patch panel, and push gently until you hear a click, indicating a secure connection. Ensure that the cable is routed through cable management trays to avoid excessive tension or sharp bends that could damage the internal glass fiber.
What to consider before purchase
Verify that your networking equipment supports LC connector interfaces
Ensure the OS2 singlemode specification matches your existing network infrastructure
Measure the required distance to confirm that 50 meters is sufficient for your installation
Usage recommendations: Always inspect the connector tips for dust or debris before installation. Use a fiber optic cleaning tool if necessary to ensure optimal signal performance. Avoid bending the cable beyond its minimum bend radius to prevent permanent signal degradation.
