SFP0-3027-L 5GBS 2X4 Ports SFP Cage&Connector Without Leds

F-tone SFP0-3027-L 2x4 Port SFP Stacked Cage and Connector Assembly

Engineered to maximize faceplate I/O density in demanding enterprise networking and telecommunications infrastructure, the F-tone SFP0-3027-L is a highly integrated 2x4 (8-port) stacked SFP cage and connector assembly. By organizing eight Small Form-factor Pluggable (SFP) ports into a compact, ganged 2x4 matrix (57.80mm overall width), this mechanical receptacle enables hardware architects to radically increase port capacity on standard 1U and 2U rack-mount networking chassis. Designed to support highly reliable data transmission rates up to 5 Gb/s per channel, it serves as an exceptional physical layer housing for Gigabit Ethernet, Fibre Channel, and high-speed storage interconnects.

Constructed for high-yield automated manufacturing, this stacked assembly utilizes a completely solderless Through-Hole Press-Fit mounting mechanism. To ensure uncompromised signal integrity and long-term mechanical durability in high-vibration environments, the internal mating contacts feature heavy-duty 30u" Gold plating. This premium plating provides superior resistance against fretting corrosion and physical wear during repeated transceiver insertions and extractions.

High-Density 2x4 Ganged Architecture

The ganged 2x4 port matrix is a foundational mechanical configuration for high-capacity aggregation routers and data center edge switches.

• Integrated Electrical Interface: Unlike standalone cages that require discrete surface-mount SFP connectors, the SFP0-3027-L integrates both the mechanical shielding cage and the electrical connectors into a single pre-aligned unit. This eliminates tolerance stack-up issues during PCB assembly and ensures flawless transceiver mating.
• Streamlined Front Panel (No LEDs): Designed explicitly without integrated light pipes or LEDs, this cage offers a clean, unobstructed outer profile. This is highly advantageous for custom-bezel hardware designs, reducing internal trace routing complexity for applications that utilize external, chassis-mounted diagnostic indicator lights.

Mechanical Design & Press-Fit PCB Integration

Hardware engineers prioritize long-term mechanical reliability alongside high-throughput automated manufacturing. The SFP0-3027-L leverages advanced compliant pin technology to optimize the printed circuit board (PCB) assembly workflow.

• Press-Fit (Compliant Pin) Technology: The assembly utilizes a Through-Hole Press-Fit mounting style. The compliant pins are driven directly into plated through-holes (PTH) on the PCB, creating a cold-welded, gas-tight electrical and mechanical bond. This heavily resists physical vibration, mechanical shock, and completely eliminates the thermal stress associated with secondary wave soldering.
• Structural Rigidity: The robust metallic cage acts as a rigid guide rail system, absorbing the physical stress of frequent SFP transceiver insertions and extractions, thereby protecting the delicate internal electrical contacts.
• Advanced EMI Shielding: The contiguous metallic structure aggressively contains internal high-frequency emissions generated by the PHY transceivers, significantly reducing near-end crosstalk (NEXT) between the 8 stacked modules and ensuring strict electromagnetic interference (EMI) regulatory compliance.

Hardware Layout & Routing Considerations

When routing for the SFP0-3027-L, PCB layout designers must carefully manage the high-speed differential pairs for all eight ports, ensuring meticulous trace length matching to maintain the 5 Gb/s signal fidelity across upper and lower rows. Due to the press-fit application, the motherboard must be fabricated to strict plated through-hole (PTH) tolerance specifications to ensure optimal pin retention force and solid electrical grounding to the chassis.

Typical Applications

Combining massive 8-port stacked density, premium 30u" gold contact plating, and a highly reliable press-fit design, the SFP0-3027-L is the optimal interconnect solution for high-throughput network architectures:

• Data Center & Enterprise Switching: High-density Top-of-Rack (ToR) switches, core edge routers, and enterprise network aggregation devices requiring maximized faceplate port matrices.
• Storage Area Networks (SAN): Fibre Channel storage arrays and high-throughput Host Bus Adapters (HBAs) requiring reliable 5 Gb/s physical layer connections.
• Telecommunications Infrastructure: Broadband access hubs, 5G baseband processing units (BBUs), and high-capacity optical transport network (OTN) switching fabrics.
• Industrial & Edge Computing: Ruggedized industrial Ethernet switches and micro-data center nodes deployed in environments demanding robust, vibration-resistant press-fit I/O ports.
