Discover our primary range of single compression glands and high-protection connectors engineered to safeguard sensitive telecommunications hardware against extreme environmental ingress and mechanical stress.
Accelerating global deployments in dense 5G NR (New Radio), fiber-to-the-antenna (FTTA), and decentralized edge computing require unyielding cable entry termination systems.
In modern telecommunication infrastructure, the integrity of signal transmission and long-term hardware reliability fundamentally depend on enclosure ingress defense. Single compression glands for telecommunication enclosures serve as the primary defensive barrier at cable entry interfaces. Unlike double-compression variants that grip both inner and outer sheaths along with mechanical armor layers, single compression glands are optimized for unarmored, flexible power feeds, RF coaxial jumpers, and hybrid fiber-optic lines. They compress a single elastomeric sealing ring (such as Neoprene, EPDM, or Silicone) firmly around the cable's outer jacket. This design simultaneously achieves a gas-tight, liquid-impermeable seal (rated up to IP68/IP69K) and substantial mechanical strain relief in an exceptionally compact footprint.
High-frequency millimeter-wave (mmWave) and massive MIMO active antenna units require compact, lightweight cable entries with ultra-high IP ratings that resist torrential rain, wind-driven dust, and solar UV radiation.
Outdoor enclosures operate across extreme diurnal temperature swings (-40°C to +100°C). Single compression elastomeric seals maintain continuous radial pressure without causing cold flow or jacket pinching.
Nickel-plated brass and stainless steel single compression glands integrate 360-degree ground contact springs or contact rings to dissipate stray RF interference and high-voltage atmospheric surges.
Understanding where and why single compression technology outperforms bulkier connectors in high-density telecommunication enclosures.
The fundamental operating principle of a single compression gland involves the axial translation of mechanical torque into radial sealing displacement. When the gland compression nut is threaded onto the gland body, it drives an internal clamping ring (or anti-friction washer) against a conical elastomeric seal. This axial thrust forces the elastomeric ring inward, creating a uniform radial seal around the perimeter of the cable jacket.
In telecommunications applications, maintaining correct radial clamping force is critical. Over-compression can crush delicate micro-duct optical fibers or alter the dielectric characteristics of 50-ohm coaxial cables, degrading Voltage Standing Wave Ratios (VSWR). Under-compression risks moisture penetration under cyclic sub-atmospheric pressures caused by internal cabinet cooling cycles. Our engineering profiles feature precision-beveled rubber seals that prevent jacket distortion while guaranteeing full submersion sealing.
Telecommunication enclosures—such as outdoor base transceiver stations (BTS), cross-connect cabinets, and optical distribution frames (ODFs)—suffer from extreme space constraints on lower entry gland plates. Single compression cable glands feature a streamlined body diameter and narrow hex profile, enabling high-density port spacing (pitch) on bottom bulkheads without wrench interference during field maintenance.
Additionally, with the global transition toward pre-terminated hybrid breakout cables, single compression glands with split grommets or slotted inserts allow multi-fiber feeds and multi-conductor DC power lines to pass through a single knock-out, drastically saving enclosure footprint and reducing installation time by up to 60%.
