The J599/MT series of products is a high-density and environmentally resistant circular fiber optic connector developed based on the J599 series and MIL-DTL-38999 Series of circular fiber optic connectors, using standard MT multi-core rectangular fiber optic contacts and precision. The J599/MT series of products is a high-density and environmentally resistant circular fiber optic connector developed based on the J599 series and MIL-DTL-38999 Series of circular fiber optic connectors, using standard MT multi-core rectangular fiber optic contacts and precision guide pin. This J599/MT series of products is based on J599 series circular fiber optic connectors, using standard MT high-density fiber optic ferrules. The connectors are quickly connected with three-head threads and use five Key positioning, supporting blind insertion, anti-corrosion, and anti-vibration. The J599MT Series Fiber Optic Connector is a high-density, circular fiber optic connector developed on the GJB599Ⅲ platform and designed for harsh-environment applications. By adopting 12-core / 24-core MT fiber contacts, this series enables compact, high-channel-count optical transmission while. Military-grade J599 MT Series connectors for harsh environments. Combines fiber optic and power transmission with blind-mate design, vibration resistance, and low loss. Ideal for aerospace and defense.
