Price OSFP optical module 400G

400G OSFP optical modules typically range from $2,000 to $6,000 per unit, depending on form factor, optical reach, modulation, and brand.

Price Overview

The cost of a 400G OSFP (Octal Small Form-factor Pluggable) optical module varies widely due to multiple factors. Standard short-reach modules like SR8 for 100m multimode fiber often start around $2,000–$3,000, while longer-reach modules such as DR4, DR4+, FR4, or LR4 for distances up to 2 km or more can range from $3,500 to $6,000 or higher . Premium brands with extended warranties or certified interoperability may add a 20–30% price premium over generic modules .

Factors Affecting Price

1. Form Factor and Compatibility OSFP modules are slightly larger than QSFP-DD modules, offering better thermal dissipation and supporting advanced PAM4 DSP chips. The larger footprint and niche market share can increase per-unit costs by 5–15% compared to QSFP-DD .
2. Optical Reach and Modulation Modules using PAM4 signaling for 400Gbps over 4 lanes require advanced DSP chips, adding 20–40% to the cost compared with NRZ-based 100G modules. Long-reach DWDM or ZR4 modules for metro and long-haul networks are significantly more expensive due to external amplifiers and tighter channel spacing .
3. Brand, Warranty, and Certification Well-known OEMs like InnoLight or FS provide certified modules with 2–3 year warranties, which increases cost. Generic or white-box modules are cheaper but may lack extended support .
4. Connector and Fiber Type OSFP modules use MPO-12 or MPO-16 connectors depending on the architecture (e.g., SR8, DR4+), and multimode vs. single-mode fiber can influence the bill of materials and final price .

Example Modules

• InnoLight T-RS4CNT-N00 DR4+ OSFP112: 400G, 2 km reach, PAM4, MPO-12 connector, suitable for high-performance data transmission .
• QSFPTEK 400G OSFP SR8: Short-range 100m, PAM4, MTP/MPO-16 connector, ideal for data centers and cloud networks .
• FS 400G OSFP Modules: High-performance, cost-effective options for 400GbE deployments .

Key Takeaway

When budgeting for 400G OSFP modules, expect $2,000–$6,000 per unit, with higher prices for long-reach, high-performance, or branded modules. Consider form factor compatibility, optical reach, modulation type, and warranty to optimize total cost of ownership .
