Compared with single-core jumpers, dual-core soft jumpers refer to two single-core jumpers combined together, also known as figure-8 optical cables.
Jacket Material: PVC, LSZH.
Features flexibility, agility and easy operation.
Suitable for use in optical components such as pigtails and jumpers.
Products can be designed according to customers' specific requirements.
Excellent flame-retardant performance, easy peelability, and high and low temperature stability.
