38999 Series III-Type Fiber-Optic and Hybrid Connectors
Fiber + power + coax + data in one 38999 shell · ≤ 0.6 dB
Fiber-Optic & Hybrid Connectors
Connectors that carry optical fiber alongside power and signal — 38999-type fiber and hybrid connectors, and subsea optical-electrical hybrids.
Fiber links carry high-speed data without EMI, but the equipment still needs power and electrical signals. Hybrid connectors put all of them through one shell.
Our 38999 Series III-type fiber-optic connectors mix fiber, power, 50 Ω coax to 18 GHz and 1.65 Gbps differential contacts, with optical insertion loss ≤ 0.6 dB. For underwater use, GDM hybrid connectors combine power contacts with 4 optical channels.
