Low-power optical module QSFP28 with Canadian landed price

Low-power QSFP28 modules, such as PAM4 or CWDM4 variants, typically consume 3–6W and can be purchased in Canada with landed prices around CAD 1,200–1,500 per module.

Overview of Low-Power QSFP28 Modules

QSFP28 (Quad Small Form-Factor Pluggable 28) modules support 100G Ethernet by aggregating four 25G lanes, offering high bandwidth density with low power consumption . Low-power variants, such as PAM4 QSFP28, are optimized for short-range data center interconnects, consuming less than 5W per module, making them ideal for high-density deployments . Other low-power options include CWDM4 QSFP28, which supports single-mode fiber links up to 2–10 km while maintaining energy efficiency .

Key Technical Features

• Electrical Interface: CAUI-4, four independent 25G lanes
• Optical Interface: Duplex LC for CWDM4, MPO/MTP for SR4
• Power Consumption: Typically 3–6W depending on variant and temperature range
• Reach:
  • SR4: up to 100 meters over multimode fiber
  • CWDM4: 2–10 km over single-mode fiber
  • PAM4: optimized for short-range, low-power DCI links
• Temperature Range: 0°C to 70°C for standard modules; industrial variants may extend to –40°C to 85°C

Canadian Landed Pricing

For Canadian buyers, Molex QSFP28 100G CWDM4 modules are available with DDP pricing, which includes duties, customs, and shipping fees. Typical landed prices are approximately CAD 1,200–1,500 per module, depending on vendor, quantity, and shipping method . This makes them a cost-effective choice for enterprise and data center deployments requiring low-power, high-density 100G connectivity.

Vendor Options

• Molex: CWDM4 QSFP28, RoHS compliant, 0–70°C, Canadian DDP pricing
• Smartoptics: PAM4 QSFP28 for short-range, low-power applications, suitable for high-density DCI
• Cisco: QSFP28 100G ZR for longer reach (up to 80 km), slightly higher power (5.5–6W), suitable for metro or campus interconnects

Recommendation

For low-power, cost-efficient 100G deployment in Canada, PAM4 or CWDM4 QSFP28 modules are recommended. They provide a balance of low power consumption, adequate reach for data center interconnects, and predictable landed costs. For longer distances or metro networks, coherent QSFP28 modules like Cisco 100G ZR can be considered, though they consume more power and have higher costs.
