## Long description

The EFB Elektronik O2519.3 is a high-performance fibre optic patch cable designed for reliable data transmission in demanding network environments. Measuring 3 meters in length, this single-mode cable features precision LC to LC connectors with APC polishing, ensuring minimal signal loss and high return loss performance. Built with G.657.A2 fibre technology, it offers excellent bend resistance, making it an ideal choice for complex cabling infrastructures where space is limited.
Advantages
This patch cable utilizes a high-quality LSZH (Low Smoke Zero Halogen) jacket, which enhances safety by reducing toxic emissions in the event of fire, making it suitable for indoor installations in data centers and office buildings. The I-V(ZN) H construction provides robust physical protection for the internal fibre, ensuring long-term durability and signal integrity. Its compatibility with single-mode systems and the use of APC connectors allow for high-precision connections required in modern telecommunications and high-speed data networks.
Suitable for
High-speed data center networking
Telecommunications infrastructure
Fiber-to-the-Home (FTTH) installations
Enterprise local area networks (LAN)
When it may not be suitable
This cable is designed specifically for single-mode applications and will not function in multi-mode fibre optic systems. Additionally, the 3-meter length may be insufficient for long-distance outdoor runs or inter-building connections without appropriate protective conduit or housing.
