Couplings, splicing cassettes and excess lengths are installed in smallest spaces by adhering to the minimum bending radii of >50mm. The modules can be individually equipped with all common SX and DX couplings and accept up to 24 FO. The splice cassette and the excess length are mounted on the module carrier. Break-outs that are not needed can be closed using blind plugs. Module fastening is done by using captive screws. The slide-on module includes a labelling option and will be delivered with one already installed labelling strip.
