1658723-2 SFP 1X4 Cage Assembly 4 Gbs Connector Solder Through Hole Press-Fit Mount

1658723-2: 1x4 SFP Ganged Cage Assembly with EMI Springs (4 Gb/s, Press-Fit)

Designed for maximum front-panel port density and uncompromising signal integrity, the 1658723-2 is a high-performance 1x4 (4-port) ganged SFP cage assembly. Engineered to house Small Form-factor Pluggable (SFP) optical transceivers and direct-attach copper (DAC) cables, this integrated cable-to-board housing supports robust data transmission rates up to 4 Gb/s. By grouping four SFP ports into a single, contiguous mechanical structure, hardware architects can drastically optimize PCB real estate while streamlining high-volume chassis assembly.

Built to endure severe environmental extremes, the 1658723-2 operates flawlessly across an industrial temperature range of -55°C to 85°C. Utilizing a reliable solderless Through Hole Press-Fit mechanism, this cage assembly ensures a permanent, highly secure mechanical connection to the printed circuit board (PCB) without subjecting the board to the thermal stress of secondary reflow processes.

High-Density 1x4 Ganged Architecture

The ganged 1x4 matrix configuration is essential for modern data center switching and telecommunications equipment. Compared to routing and mounting four independent, single-port SFP cages, the 1658723-2 guarantees perfect port-to-port alignment, simplifies PCB trace routing, and provides unified mechanical rigidity. Rated for 4 Gb/s, it is the ideal physical housing for Gigabit Ethernet (1GbE), SONET/SDH, and up to 4G Fibre Channel (4GFC) topologies.

Advanced EMI Containment & Grounding

Managing Electromagnetic Interference (EMI) at the chassis faceplate is a critical design consideration for high-frequency networking hardware. The 1658723-2 achieves superior electromagnetic compatibility (EMC) through its integrated EMI springs.

• Multi-Point Chassis Grounding: Metallic EMI springs surround the cage opening, ensuring continuous, low-impedance electrical contact with the metallic chassis bezel or faceplate.
• High-Frequency Shielding: Aggressively blocks external Radio Frequency Interference (RFI) while containing internal high-frequency emissions generated by PHY transceivers, ensuring strict compliance with FCC and CISPR regulations.
• Internal Isolation: The internal divider walls of the ganged cage function as Faraday shields, virtually eliminating crosstalk between adjacent high-speed SFP modules.

Mechanical Design & Press-Fit PCB Integration

Hardware engineers prioritize long-term mechanical reliability and simplified manufacturing. The 1658723-2 leverages advanced press-fit pin technology to achieve both.

• Press-Fit (Compliant Pin) Technology: Eliminates the need for wave soldering. The compliant pins are pressed directly into plated through-holes (PTH) on the PCB, creating a cold-welded, gas-tight electrical and mechanical connection that resists vibration and thermal cycling.
• Structural Rigidity: Acts as a rigid mechanical guide rail system, absorbing the physical stress of frequent SFP transceiver insertion and extraction, thereby protecting the delicate SFP surface-mount electrical connectors located beneath the cage.
• Thermal Endurance: The military-grade -55°C to 85°C operating range guarantees uninterrupted physical protection for optics in unconditioned outdoor enclosures, industrial factory floors, and aerospace applications.

Typical Applications

Offering uncompromising multi-port density, rapid solderless assembly, and extreme temperature resilience, the 1658723-2 SFP cage is the optimal choice for rugged, high-bandwidth networking infrastructure:

• Telecommunications Infrastructure: Broadband aggregation routers, Central Office (CO) switches, and outdoor 5G cellular base station equipment.
• Enterprise & SAN Networking: High-density Gigabit Ethernet switches and 4G Fibre Channel storage area network arrays.
• Industrial Automation: Hardened Industrial Ethernet (IE) switches deployed in extreme manufacturing and energy sector environments.
• Defense & Aerospace: Ruggedized communication hubs requiring military-grade temperature tolerances and vibration-resistant press-fit mountings.
