Description

COTS M83526 2-4 CH Connector Family

Optical Cable Corporation introduces the next generation of Tactical Fiber Optic Connector family based on the retired MILPRF-83526 performance specification. This tactical fiber optic connector system features a "field convertible" hermaphroditic fiber optic plug component COTS-83526 PLUG connector with integrated strain relief and tactical cable retention systems.

Available in either 4 or 12 channel shell sizes (2, 4, 6, 8 and 12 CH options), this family of tactical fiber optic connectors also features specifications for a wide variety of harsh environment companion receptacles including Internal Jam-Nut, External Jam-Nut, and Flange Mount receptacles as well as similar companion configurations with Integrated Strain Relief systems.

At the heart of this robust family of tactical/deployable hermaphroditic fiber optic connectors is the TC1640CA ™environmentally sealed™ terminus system, which affords superior optical performance while maintaining resistance to dust, moisture or even liquid submersion.

This new terminus system features a "free-floating" environmentally sealed capability utilizing commercially available 2.5mm ceramic ferrules, relying on the Insert Cap of the COTS-83526 connectors to retain the ceramic alignment sleeve. This new termini is corrosive-resistant, easily inserts at 90™ angles to the termini retainer and functions as a "genderless" termini (can be either pin or socket) when used in the hermaphroditic design of the COTS-83526 connector system.

Why Hermaphroditic?

Hermaphroditic connectors are designed for quick deployment and gender-independent connectivity, allowing the end user to un-reel fiber cable without regard for identification of the male or female ends. The hermaphroditic design enables the transmission path to maintain polarity even with multiple cable segments daisy-chained together to extend the distance of the deployable system.

Features

• The M83526 is interoperable, inter-mateable in accordance with the reitred MIL-PRF-83526/16, /17 interface specification which makes it backward compatible with most fielded M83526 4 CH and 12 CH connectors and essentially using the same assembly procedures and tools.
• Field Convertible Hermaphroditic Plug allows Plug-to-Plug assembly on a reel to be instantly provisioned for male (daisy chain) or female connectivity.
• The Field Convertable Hermaphroditic Dust Plug Cap is instantly provisioned with mating dust cap to allow dust cap coupling.
• Ceramic Split Sleeves are retained within the Insert Cap, preventing sleeves becoming misplaced during maintenance routines.
• Enhanced Kevlar Retention System supports 400 lb. cable retention without degradation of optical signal.
• Sealed Termini Design for 4 CH, 6 CH, 12 CH, and 24 CH Systems utilize Sealing, Environmental Resistance to meet IP-68 requirements.
• COTS-83526 Integrated "Push-Pull" system allowes operators to easily terminate COTS-83526 Plugs and Receptacles in an efficient, non-complex format.
• Dry Film Thread Lubrication extends life of mating threads, self-lubricating through repeated mating cycles.

Applications

• Mobile Emergency Telecommunications Stations
• Mobile Tactical Shelters
• United States Army, Navy, and Marine Corps military tactical deployments
• Deployable Trailers for Federal Emergency Management Agency
• Homeland Security
