Price List for 100G Optical Line Terminals for Smart Cities

100G OLTs and optical transceivers for smart city networks range from $35 for short-reach modules to over $20,000 for long-haul coherent solutions, depending on type, distance, and vendor.

100G OLT and Optical Module Types

For smart city deployments, 100G OLTs typically use the following optical modules:

• QSFP28: Compact, high-density modules with four 25Gbps channels, suitable for short- to medium-distance links (100GBASE-SR4, PSM4, LR4) and increasingly popular for urban networks due to space efficiency and lower power consumption .
• CFP/CFP2/CFP4: Larger modules supporting 100Gbps transmission over various distances. CFP2 and CFP4 are smaller and more power-efficient than CFP, making them suitable for higher-density OLTs .
• CPAK: Vendor-specific pluggable modules (e.g., Cisco) for 100GBASE-LR4, CWDM4, and PSM4 applications, supporting distances from 500m to 10km .

Typical Price Ranges

Pricing varies based on reach, technology, and brand:

• Short-reach 100G SR/PSM4 modules: $35–$250 per unit for compatible or third-party modules .
• Medium-reach 100G LR4/CWDM4 modules: $200–$1,000 per unit, suitable for metropolitan area networks .
• Long-haul 100G DWDM or coherent modules: $2,000–$20,000+, used for inter-city or high-capacity backbone links .
• Active Optical Cables (AOC) and Direct-Attach Copper (DAC): 1–30m lengths, $50–$500 depending on length and speed, often used for short interconnects within OLT racks .
• Remanufactured or vendor-certified modules: Cisco 100G QSFP, CPAK, and NCS6000 linecard optics are available in remanufactured form, offering cost savings while maintaining compatibility .

Vendor Options

Recommendations for Smart City Deployments

1. Short-distance urban links: Use QSFP28 SR4 or PSM4 modules for cost-effective, high-density OLTs.
2. Medium-distance metro links: LR4 or CWDM4 modules provide reliable 10km connectivity.
3. Long-distance backbone: Consider DWDM or coherent 100G modules for inter-city or high-capacity links.
4. Cost optimization: Evaluate remanufactured or third-party modules for non-critical links to reduce procurement costs without compromising performance. By selecting the appropriate module type and vendor, smart city networks can balance performance, density, and cost, ensuring scalable 100G OLT deployment.
