Price per unit of 10 Gigabit optical module

The price of a 10G SFP+ optical module typically ranges from $10 to $300 per unit, depending on type, distance, and brand.Price Range Overview

The cost of a 10G SFP+ module varies widely based on transmission distance, optical technology, and brand. For standard enterprise and data center deployments:

• Short-range (SR) multi-mode modules: Usually at the lower end of the range, around $10–$50, suitable for distances up to 300–400 meters using OM3/OM4 fiber .
• Long-range (LR) single-mode modules: Typically $100–$300, designed for distances up to 10 km, with higher optical power and stricter manufacturing tolerances .
• Extended range (ER, ZR, EX): Can exceed $300, supporting distances from 40 km to 120 km, often used in backbone or carrier networks .

Factors Affecting Price

1. Transmission Distance: Longer distances require single-mode optics and higher precision, increasing cost.
2. Brand and Vendor: Branded modules from Cisco, Juniper, or other major vendors are often priced multiple times higher than compatible third-party modules due to support contracts and vendor lock-in .
3. Compatibility: Modules certified for specific switches or routers may cost more.
4. Optical Type: Multi-mode modules are cheaper than single-mode modules for equivalent speeds.

Practical Buying Tips

• For data centers or enterprise networks, compatible SR modules are cost-effective and reliable for short distances.
• For backbone or long-distance links, LR or ER modules are necessary despite higher cost.
• Always verify vendor compatibility to avoid network issues, especially when using third-party modules. In summary, a typical 10G SFP+ module costs between $10 and $300 per unit, with multi-mode SR modules at the lower end and single-mode LR/ER modules at the higher end, influenced by distance, brand, and optical specifications .
