    Transmission wavelength of single-mode optical cable

    Unlike, single-mode fiber does not exhibit. This is due to the fiber having such a small cross section that only the first mode is transported. Single-mode fibers are therefore better at retaining the fidelity of each light pulse over longer distances than multi-mode fibers. For these reasons, single-mode fibers can have a higher than multi-mode fibers. Equipment for single-mod.
