High Speed SFP / SFP+ / QSFP28 Cage & Pluggable Connectors

Product Specification

EMI Shielded Cage with Optional Heat Sink | 1G /10G /25G /100G Signal Transmission Compatible with SFP, SFP+, QSFP28, XFP, CFP Fiber Optic Transceivers

Product Description

Our SFP & QSFP series high-speed cage assemblies serve as the PCB-side receptacle for fiber optical transceivers & DAC cables. Equipped with a full 360° EMI shielding structure and an optional riding heat sink, these pluggable connectors support 1G,10G,25G,100G high-speed signal transmission. Widely available in 1x1 single-port & 1xN stacked multi-port configurations. Fully compliant with SFF MSA industrial standards, perfectly deployed in 5G telecom infrastructure, enterprise switches, servers, data center storage, and industrial communication hardware.

Product Series Overview

Remark: All models support SMT solder tail or Press-Fit termination; customized stacked port layout available upon request.

Core Competitive Advantages

✅ Optimized EMI Suppression for High-Speed Signal
Full surrounding BeCu EMI spring fingers achieve 360° shielding. Effectively restrain crosstalk & electromagnetic leakage during 10G/25G/100G high-speed operation, helping your equipment pass CE/FCC EMC testing. Many low-cost competitors only adopt a partial spring design and cause EMI failure risk.
✅ Dual Thermal Solutions: Standard Cage & Heat Sink Version
We provide bare vented cages and pre-assembled cages with an aluminum heat sink. The heat sink model efficiently reduces transceiver operating temperature, avoiding thermal throttling for high-power optical modules, critical for long-term stable running in 5G base stations and dense data center racks.
✅ Rich Port Layout Options (1×1 / 1×N / Vertical Stacked)
In stock for single-port 1×1, multi-port ganged 1×4, and belly-to-belly 2×1 stacked structures. Support low-profile LP / straight/right-angle orientation, match different 1U/2U switch & server chassis design requirements.
✅ Strict MSA Standard Dimensional Control & Interoperability
All cages follow official SFF MSA mechanical drawings. Precision stamping & mold control guarantee interchangeability with mainstream brands’ optical transceivers, with no stuck insertion or poor contact issues.
✅ One-Stop Customization Support
Light pipe, shutter door, customized heat sink, special PCB footprint, and revised EMI spring layout are acceptable. We can output 3D STEP files & detailed datasheet for your hardware design team.
✅ Factory Direct Supply & Stable Batch Consistency
Self-owned stamping, molding & assembly workshop. Strict IPC-A-610 inspection standard. Avoid unstable quality from trading companies; support small sample trials and mass-volume orders.
✅ Two Termination Options Available
SMT solder tail for general projects; Press-fit compliant pin for high-layer PCB, eliminating reflow heat damage to the mainboard.
