Polarization maintaining fiber jumper, high extinction ratio

Polarization maintaining fiber jumpers, high extinction ratio: The ER of these polarization maintaining (PM) fiber jumpers is defined as the ratio of the optical power propagating along the slow axis of the fiber to the optical power propagating along the fast axis of the fiber when the incident light with near excellent line deviation is aligned with the slow axis of the fiber. Please note that the extinction ratio that can be achieved using high extinction ratio PM jumpers in the system may be lower than the specified extinction ratio of the jumpers.

Our high extinction ratio (ER) polarization maintaining fiber jumpers are specially designed to have high extinction ratio and low insertion loss compared to our standard polarization maintaining fiber jumpers (please refer to the comparison label for specific differences between the standard and high extinction ratio versions).

The ER of these polarization maintaining (PM) fiber jumpers is defined as the ratio of the optical power propagating along the slow axis of the fiber to the optical power propagating along the fast axis of the fiber when the incident light near the defect line is aligned with the slow axis of the fiber. Please note that the extinction ratio that can be achieved using high extinction ratio PM jumpers in the system may be lower than the specified extinction ratio of the jumpers. This is because the achievable ER is always limited by optical components with lower ER in the system. The assembly and testing of these jumpers are only applicable to slow axis performance. Although the ER achievable when using a fast axis may be similar, we have not tested and cannot guarantee performance in this situation. For more information on extinction ratio measurement methods, please refer to the ER measurement label.

Each jumper is individually tested at the aligned wavelengths listed below to ensure the extinction ratio and insertion loss at the fiber optic connection. Each jumper wire contains two protective caps to prevent the end of the plug from being affected by dust and other pollutants. Other CAPF plastic protective caps and CAPFM metal threaded protective caps used for FC/PC and FC/APC terminals are sold separately.

In addition to the standard products provided below, jumpers of different lengths and sheaths can also be customized. For more information, please contact our technical support.
