Mode Conditioning Cables from Huihong Fiber

October 23, 2019

The mode conditioning cable is a double multimode jumper with a small length of single mode fiber at the beginning of the transport length. This cable is designed to regulate laser emission and achieve an effective bandwidth such that the effective bandwidth is close to the bandwidth measured using the overflow emission method. The mode conditioning cable allows the laser transmitter to operate at gigabit rates when using multimode fiber. Will not be limited by the modulus delay. The key point is that a greater number of modes are excited in the fiber, and trade-offs are made in the mold system, where the overflow emission conditions highly motivate the mold system, avoiding extensive excitation of individual mold systems having the same power level. The laser can be launched into a single mode fiber and then connected to a multimode fiber. The access point is off center with respect to the fiber core of the single mode fiber.

Different offsets are required for 50μm and 62.5μm multimode fibers. Engineers have found that an offset of 17~23μm can achieve a bandwidth equivalent to the effective mode of the 62.5μm multimode fiber-optic overflow emission method. An offset of 10~16μm is better for 50μm multimode fiber.
mode conditioning patch cable for running Gigabit Ethernet on existing multimode fiber optic plants. These cables operate at 1300 nm to prevent modal dispersion, and their centerline offset stitching keeps the cores center-to-center, allowing for transitions from single mode to multimode. We offer a variety of mode adjustment cable options, from various types of connectors to different fiber modes to jackets of different lengths. We offer a variety of fiber optic connectors including LC/UPC, SC/UPC, FC/UPC, ST/UPC, LC/APC, SC/APC, FC/APC, E-2000 and MTRJ.
