List of Single-Core Fiber Optic Cold Joint Models

Single-core fiber optic cold joints are available as cold-shrink monoblock joints and single-channel fiber optic rotary joints (FORJs) for single-mode fibers.

Cold-Shrink Single-Core Joints

Cold-shrink joints are designed for tool-free, safe installation in outdoor, underground, and underwater environments. Each kit typically contains one single-core joint, pre-dilated on a spiral support for easy removal and installation. These joints are suitable for extruded cables up to 12/20 kV (Um 24 kV) and are compact, complete with all necessary components for rapid deployment .

Single-Channel Fiber Optic Rotary Joints (FORJs)

Single-channel FORJs allow optical signals to pass across rotating interfaces while maintaining low insertion loss and high return loss. They are ideal for single-mode fibers, which require precise mechanical alignment due to their small core size and numerical aperture . Key models include:

  • Princetel R Series: Standard base models include RPT, RFC, and RST, supporting ST, FC/PC, or pigtail receptacles. These models are rugged, dust- and water-tight, and can operate in extreme low temperatures and high humidity environments .
  • Moog Single-Channel FORJs: Cost- and size-efficient single-channel designs, with options to stack modules for multi-fiber systems. Designed for high bandwidth and precise alignment for single-mode fibers .
  • SPINNER Single-Channel FORJs: Available in three standard versions and customizable solutions, ensuring minimal insertion loss and high-speed data transmission. These are suitable for EMI/EMC-sensitive and harsh environments .

Summary

For single-core fiber optic cold joints, users can choose between cold-shrink monoblock joints for static cable connections and single-channel FORJs for rotating or dynamic applications. Each type offers models optimized for environmental conditions, fiber type, and installation requirements, ensuring reliable optical performance in demanding applications .
