The CommScope FOSC450-C6-6-24-1-C6V (Millennium part #41986, vendor #AV134A-000) is a 7.26 kg single-ended fiber splice closure built for buried and below-ground fiber optic cable installations. It ships with one pre-installed 24-splice tray, six cable attachment ports, and six ground feedthrough lugs with an integrated test valve for verifying seal integrity. The impact-resistant polymer housing supports up to 1,152 fibers via mass fusion splicing and 288 fibers via single fusion, meeting IEC 61300 water-resistance standards with a 5-meter waterhead rating. This closure is a strong fit for feeder network fiber builds requiring durable, field-tested splice protection.
