dual wavelength design easy change-out of attenuation values single-mode precision sleeve molded latches operable at 1310 nm and 1550 nm no tools required provides precise alignment snap mount into sc panels features and benefits | corning cable systems universal build-out optical attenuators are designed to interconnect single-mode connectors with or without attenuation. offered in fc, lc, sc, or st ? compatible styles, these attenuators are available in 0-16, 18 and 20 db levels. the unique design allows for easy change-out of attenuation values with no tools required. the 0 db offering is very useful for connections where no attenuation is required. each build-out attenuator requires the use of a build-out block (sold separately) that replaces the standard adapter. the sc build-out block has molded latches for snap mounting into sc panels. the st ? compatible build-out block is equipped with a lock washer and circular nut for mounting into st compatible bulkhead adapter panels. universal build-out attenuators meet dual-wavelength requirements for insertion loss at 1310 and 1550 nm while achieving reflectance performance of -40 db for single-mode applications and attenuation tolerances of 15 percent of nominal attenuation. optical attenuators | photo cnpss1717 universal build-out 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-987-en | page 1
