1761007-2 SFP 1X2 CAGE 4 Gbs EMI Springs With Lightpipe

1761007-2 SFP 1x2 Ganged Cage Assembly | 4 Gb/s Press-Fit Receptacle with Integrated Lightpipes

Expert Architecture Insight: Integrated Lightpipes & Visual Diagnostics

A defining architectural advantage of the 1761007-2 is its Integrated Lightpipes. In densely populated switch faceplates, inserted optical transceivers often obscure the board-mounted diagnostic LEDs. The integrated lightpipes utilize total internal reflection to channel the light signal from the motherboard's LEDs directly to the front bezel of the SFP cage. This provides network operations center (NOC) engineers with immediate, port-level visual feedback (Link/Activity status) without requiring software polling or external diagnostic tools, drastically reducing troubleshooting time and operational expenditures (OPEX).

Press-Fit Assembly & High-Density Integration

Operating flawlessly across an extreme temperature range of -55°C to +85°C, this dual-port SFP cage is built to streamline PCB manufacturing and maximize mechanical integrity:

• Solderless Press-Fit Termination: Features resilient "Eye-of-the-Needle" compliant pins designed for Through-Hole Press-Fit mounting. This eliminates the need for high-temperature wave soldering, protecting the thermal integrity of complex multi-layer motherboards and accelerating automated assembly.
• 1x2 Ganged Configuration: Integrates two SFP ports into a single continuous metal housing. This "ganged" design saves critical horizontal PCB real estate and ensures perfect coplanarity between ports, which is vital for aligning with equipment faceplates.
• Exceptional EMI Shielding: Equipped with robust external EMI springs that create a continuous 360-degree conductive ground path to the equipment chassis. This effectively contains high-frequency RF noise and prevents electromagnetic interference in packed racks.
• 4 Gb/s Throughput Rating: Optimally tuned for up to 4 Gb/s data rates, making it the perfect, cost-effective mechanical housing for standard 1.25G Gigabit Ethernet (1000BASE-X), SONET/SDH, and 4G Fibre Channel, without over-specifying to 10G/28G hardware.

Typical Applications & Industry Use Cases

Due to its rugged press-fit design, port-level lightpipe diagnostics, and 4 Gb/s capability, the 1761007-2 is the preferred housing for:

• Enterprise Networking: 1x2 SFP uplink ports on Gigabit Ethernet switches, hardware firewalls, and unified threat management (UTM) appliances.
• Storage Area Networks (SAN): 4G Fibre Channel host bus adapters (HBA) and high-availability clustered storage arrays requiring immediate visual link status.
• Telecom Infrastructure: Baseband units, optical transport networks (OTN), and outdoor edge routers exposed to extreme temperatures (-55°C to +85°C).
• Industrial Communication: Ruggedized industrial PCs (IPC) and media converters deployed in harsh, unconditioned environments.
