product description
The polarization maintaining jumper series has excellent environmental stability, high return loss, and low insertion loss, making it an ideal choice for applications in PM amplifiers, fiber lasers, and testing instruments. These jumpers are aligned using high-precision connectors and adapters to ensure that the direction of the optical axis remains consistent, thereby achieving high extinction ratio and low insertion loss.
Specific features include:
Environmental stability: The polarization maintaining jumper performs well under different environmental conditions and can adapt to storage temperatures ranging from -40 ° C to+85 ° C and working temperatures ranging from -5 ° C to+70 ° C.
High return loss: The typical return loss can reach 50 dB, ensuring signal stability and reliability.
Low insertion loss: The insertion loss is usually below 0.4 dB, ensuring the high efficiency of the signal during transmission.
High extinction ratio: The extinction ratio can reach over 23 dB, ensuring that the polarization direction of the light remains unchanged when transmitting polarized light signals and improving the coherent signal-to-noise ratio.
These characteristics make polarization maintaining jumpers very suitable for high-speed fiber optic communication, fiber lasers, fiber amplifiers, and various testing equipment, meeting strict requirements for signal integrity and high fidelity.
