ASEAN 10 Countries Telecom-Grade Router QSFP28

QSFP28 modules enable 100G Ethernet connectivity for telecom-grade routers across ASEAN networks, supporting distances from 10 km to 300 km depending on the module type.

Overview of QSFP28 Technology

QSFP28 (Quad Small Form-factor Pluggable 28) is a high-speed optical transceiver standard designed for 100G Ethernet (100GbE) connections. Each module uses four electrical lanes at 25 Gbps to achieve a total of 100 Gbps, providing high bandwidth density while maintaining low power consumption, typically 2.5 W to 6 W depending on the module and distance . QSFP28 modules are hot-pluggable, allowing installation or replacement without interrupting network operations, making them ideal for carrier-grade routers and switches in telecom networks .

Key QSFP28 Module Types for ASEAN Deployment

1. 100GBASE-LR4 QSFP28
   • Distance: Up to 10 km over single-mode fiber (SMF) with duplex LC connectors .
   • Applications: Enterprise core, distribution layers, data centers, and high-performance computing networks .
   • Features: Compliant with IEEE 802.3 100GBASE-LR4, SFF-8661, and SFF-8636 standards; supports digital diagnostics for real-time monitoring .
2. Cisco QSFP28 100G ZR
   • Distance: Up to 80 km over dark fiber and 300 km over amplified DWDM links .
   • Applications: Metro access, data center interconnect, wireless x-haul, and campus networks requiring low latency and precise timing.
   • Features: Supports ITU-T G.709.2 FEC, CMIS 5.2 management interface, and tunable C-band coherent optics for long-haul deployments .

Deployment Considerations in ASEAN

• Interoperability: QSFP28 modules are compatible with a wide range of routers and switches from multiple vendors, ensuring smooth integration across ASEAN telecom networks .
• Power and Thermal Management: Modules typically consume 2.5–6 W, requiring proper thermal design in telecom-grade routers to maintain reliability .
• Use Cases: Suitable for high-density aggregation, core routing, and long-haul interconnects in ASEAN countries, supporting both enterprise and carrier-grade networks .
• Reliability: Industrial-grade QSFP28 modules undergo extensive testing for compatibility, diagnostics, and long-term stability, which is critical for telecom-grade deployments .

Summary

For ASEAN telecom networks, QSFP28 modules provide flexible, high-speed 100G connectivity for routers and switches. Short-range modules like 100GBASE-LR4 are ideal for intra-city or data center links, while 100G ZR coherent optics support long-haul interconnects up to 300 km. Their hot-pluggable design, low power consumption, and compliance with industry standards make them suitable for carrier-grade deployments across the 10 ASEAN countries .
