special fiber insertion between connector and adapter tested to telcordia gr-910 issue 2 minimizes effect of modal interference easy installation meets performance requirements features and benefits | corning cable systems offers sc, st ? compatible, fc, mu, lc low reflection, in-line, flat wavelength optical attenuators that are easily inserted between the connec- tor and adapter in an in-line configuration and are compatible with sc, st ? compatible, fc, mu, lc and angled sc and fc connectors. these attenuators con- tain a zirconia ferrule with a specially selected attenuat- ing fiber that minimizes the effect of modal interference and gives the component a flat spectral response. it is extremely stable over the wavelength range of 1260 to 1360 nm and 1430 to 1580 nm. available in ultra pc ( -55 db) and angled pc ( -65 db) finish, these attenuators will meet the most demanding network reflectance requirements. optical attenuators | photo cnppp1473 in-line, flat wavelength optical attenuators a lanscape ? solutions product | preterminated systems | cables | connectors | cable assemblies | hardware | tool kits and accessories | test equipment | splice equipment | fan-out kits | training | specification sheet lan-988-en | page 1
