Price quote for 400G OSFP optical modules for metropolitan area networks

400G OSFP optical modules suitable for metro networks are available in DR4, FR4, and LR4 variants, with pricing typically obtained via vendor quotation.

Module Types and Metro Network Suitability

For metropolitan area networks, the following 400G OSFP modules are commonly used:

• DR4 (400G over 500 meters single-mode fiber): Ideal for short-reach metro interconnects and high-density intra-data center links, providing low-latency, high-bandwidth connectivity .
• FR4 (400G over 2 km single-mode fiber): Suitable for medium-reach metro applications, connecting multiple buildings or data centers within a city .
• LR4 (400G over 10 km single-mode fiber): Designed for longer metro links, including data center interconnects and metro access networks . These modules support PAM4 signaling and 8 electrical lanes at 50 Gbps, ensuring high-speed, low-latency performance for dense network deployments . OSFP modules also offer enhanced thermal management, making them reliable for continuous operation in power-intensive metro environments .

Pricing Guidance

Exact prices for 400G OSFP modules vary depending on vendor, module type, reach, and order volume. Typical enterprise and metro-grade 400G OSFP modules can range from $3,000 to $6,000 per module, but for precise pricing, it is recommended to request a formal quote from vendors such as FS, Transceiver USA, or Smartoptics . Vendors often provide volume discounts and shipping from regional warehouses to reduce lead times.

Recommendation

For metropolitan area networks, FR4 or LR4 OSFP modules are generally preferred due to their reach and reliability. When requesting a quote, provide the following details to vendors:

• Required link distance and fiber type
• Module type (DR4, FR4, LR4)
• Quantity and expected deployment timeline
• Compatibility requirements with existing switches or routers This ensures the vendor can provide an accurate price quote and recommend the most suitable modules for your metro network deployment.
