Purchase Enterprise-grade Optical Router QSFP28

Enterprise-grade QSFP28 routers enable 100G Ethernet connectivity with high performance, low latency, and scalable deployment options for data centers and service provider networks.

Understanding QSFP28 Optical Modules

QSFP28 (Quad Small Form-Factor Pluggable 28) is a compact transceiver form factor designed for 100G Ethernet, providing four 25G lanes per module. It supports high port density, low power consumption, and a streamlined upgrade path from lower-speed networks, making it ideal for data center interconnects (DCI), enterprise core networks, and service provider environments (Smartoptics) .

Types of QSFP28 Modules

1. PAM4 QSFP28
   • Optimized for short-range, low-power, cost-effective deployments within data centers.
   • Ideal for switch-to-switch or server-to-switch connections over tens to hundreds of meters.
2. Coherent 100G QSFP28 (100ZR)
   • Uses coherent technology to extend reach up to hundreds of kilometers.
   • Supports dense wavelength division multiplexing (DWDM), enabling up to 9.6 Tb/s on a single fiber pair without replacing existing QSFP28 ports.
   • Suitable for metro, regional, and long-haul networks, providing higher performance and wavelength tunability (Ciena, Smartoptics) .

Key Considerations for Ordering

• Compatibility: Ensure the router supports QSFP28 modules and the desired type (PAM4 or coherent). Most enterprise-grade routers from major vendors are MSA-compliant and compatible with third-party transceivers (Unitekfiber) .
• Reach Requirements: Choose PAM4 for short-range intra-data center links and coherent 100ZR for extended metro or regional connectivity.
• Scalability: Coherent QSFP28 modules allow network operators to scale capacity without replacing router infrastructure, supporting dense DWDM deployments.
• Vendor Support: Consider suppliers like FS, QSFPTEK, Smartoptics, and Ciena, which offer enterprise-grade QSFP28 modules with warranties, low-latency performance, and global shipping options (FS, QSFPTEK) .

Ordering Options

• FS: Offers a wide portfolio of 100G QSFP28 modules with 30-day free returns and multiple warehouse locations for fast delivery .
• QSFPTEK: Provides modules optimized for AI clusters and high-performance computing, including guidance on interconnecting QSFP-DD and OSFP ports for 400G/800G networks .
• Ciena: Supplies 100ZR coherent QSFP28 transceivers for long-reach, high-capacity deployments with encryption and DWDM support .
• Smartoptics: Offers both coherent and PAM4 QSFP28 modules, suitable for enterprise, metro, and regional networks .
• Unitekfiber: Wholesale supplier of MSA-compliant optical transceivers, ensuring compatibility with major OEM hardware .

Recommendations

1. Define network requirements: Determine whether your deployment is short-range (data center) or long-range (metro/regional).
2. Select module type: PAM4 for cost-effective short-range, coherent 100ZR for extended reach and DWDM scalability.
3. Verify router compatibility: Ensure your enterprise-grade router supports QSFP28 ports and the chosen module type.
4. Choose a trusted supplier: Consider warranty, support, and delivery options when ordering. By carefully selecting the appropriate QSFP28 module and compatible router, enterprises can achieve high-speed, scalable, and cost-efficient optical networking for modern data center and service provider applications.
