OC-48 to DS-3 Fiber Terminal
This is a backside view of a typical OC-48 fiber terminal, where the fiber optic input is multiplexed down to the DS-3 level. Note that each DS-3 (28 T1's) on each coaxial pair of cables is hand sewn, an art of installation which has become increasingly rare. Sirius staffs its own technical installation team well versed in the beauty of proper installation technique. It only works as well as it is installed.
