FAQ

Telecom Shielding Can Frequently Asked Questions

Why must telecom equipment shielding cans be ≥90dB?

Telecom equipment (especially base stations) characteristics:

  • High Power: Base station power amplifiers typically >50W; high-power RF signals easily generate interference;
  • Multi-Band: Single devices often shield 5G/4G/3G multi-band with high cross-interference risk;
  • Sensitive Devices: Receiver front-end and similar sensitive circuits easily disrupted with limited dynamic range;
  • Long-Distance Transmission: Signals must transmit 100km+ distances; any loss impacts network quality.

Therefore, ≥90dB efficiency is industry standard; some scenarios even demand ≥100dB.

What distinguishes optical module shielding from standard cans?

Optical Module Shielding Characteristics:

  • Micro Size: SFP optical module volume only ~10mm—cans must be ultra-micro;
  • High Integration: Laser, receiver, drive chip extreme integration with millimeter-scale isolation;
  • Thermal Requirements: Laser generates significant heat; cans cannot impede heat dissipation, requiring special processes;
  • High-Frequency: Optical communication frequencies in GHz range requiring refined shielding design.

Optical module shielding requires precision stamping and specialized material selection.

How is precision maintained for large-size shielding cans?

Large-size can (50×50mm+) precision assurance:

  • Tool Precision: ±0.01mm high-precision tool design and manufacturing;
  • Multi-Station Stamping: Progressive multi-position dies with gradual forming for uniformity;
  • Stamping Force Control: Strict pressure and speed control preventing material deformation;
  • Sizing Process: Post-stamping light sizing ensures dimensional consistency;
  • 100% Inspection: Every part inspected by CMM coordinate measuring machine.

Our large-size can dimensional consistency typically achieves ±0.03mm.

How is long-term telecom equipment reliability assured?

Base stations and similar telecom devices require 15~20 year lifespan. Our assurance measures:

  • Surface Treatment: High-quality gold/nickel plating; NSS 1000h+ corrosion resistance;
  • Material Selection: High-strength alloys (such as German silver copper) with extended fatigue life;
  • Environmental Durability: -40~70℃ thermal cycling (200 cycles), salt-spray testing confirmed;
  • Vibration Testing: Simulating base station wind vibration, earthquake dynamic loads ensuring structural reliability;
  • Aging Testing: 1000h high-temperature storage confirming material performance non-degradation.

These investments, while increasing costs, ensure network equipment long-term stable operation.
