38999 Series III-Type Fiber-Optic and Hybrid Connectors
Fiber + power + coax + data in one 38999 shell · ≤ 0.6 dB
38999 Series III-Type Differential Connectors, 1.65 Gbps
Size 8 differential · 1.65 Gbps · marine grade
These 38999 Series III-type connectors carry high-speed differential networks with matched impedance. Size 8 differential contacts (2 or 4 conductors) reach 1.65 Gbps and can be mixed with power, RF and fiber contacts in one shell. Triple-start threaded coupling with anti-decoupling suits high-vibration environments, and construction is marine grade.
