## Long description

The BlueOptics SFP2121BU50MS is a high-quality 50-meter singlemode OS2 fiber optic patch cable designed for reliable and high-speed data transmission in professional network environments. Featuring LC to LC connectors, this cable utilizes G.657.A1 fiber technology with a 9 µm core diameter to ensure optimal signal integrity. The cable is encased in a yellow LSZH (Low Smoke Zero Halogen) jacket, providing enhanced safety and durability for complex telecommunications and data center infrastructures.
Advantages
This patch cable offers exceptional performance due to its high-grade ceramic ferrule, which ensures precise alignment and minimal signal loss. The use of G.657.A1 fiber allows for tighter bend radii without compromising data throughput, making it highly versatile for installations in confined spaces. Furthermore, the inclusion of a measurement protocol guarantees that each cable meets strict quality standards before deployment, providing peace of mind for mission-critical network connections.
Suitable for
Data center interconnections
Telecommunications network infrastructure
High-speed fiber optic backbone links
Enterprise local area networks
When it may not be suitable
This cable is specifically designed for singlemode applications and will not function in multimode fiber optic systems. Additionally, the 50-meter length may be excessive for short-range connections within a single rack, where shorter cables might be more efficient for cable management.
