Price of a 40km 10G optical module

A 10G SFP+ optical module with a 40km range typically costs between $100 and $300, depending on brand and compatibility.

Price Overview

10G SFP+ modules vary widely in price based on transmission distance, optical technology, and brand. Standard short-range (SR) modules for a few hundred meters can cost as little as $20–$60, while long-range (LR/ER) modules designed for distances up to 40km are priced higher due to single-mode optics, higher optical power, and stricter performance requirements. Branded modules from major vendors often cost more than compatible third-party options, sometimes up to $300 or more for ER modules .

Example Module

The SFP-10G-ER1310 is a generic 10G SFP+ transceiver supporting 10GBASE-ER1310 throughput up to 40km over single-mode fiber. It operates at a 1310nm wavelength and features an LC duplex connector. Such modules are tested for compatibility with multi-vendor network devices and can save up to 80% compared to original branded transceivers, offering a cost-effective solution for long-distance 10G connectivity .

Factors Affecting Cost

1. Brand vs. Compatible Modules: OEM-branded modules often include warranties and vendor support, increasing cost. Compatible modules provide similar performance at lower prices .
2. Optical Technology: ER modules with DFB lasers and precise wavelength stability are more expensive than SR or LR modules .
3. Network Requirements: Modules with enhanced monitoring interfaces or tunable DWDM capabilities may cost more but provide better reliability and management .

Practical Buying Range

For a 40km 10G SFP+ module, most buyers can expect to pay $100–$300 for reliable, compatible modules, while branded or vendor-certified options may exceed this range. This makes ER modules suitable for enterprise backbones, metro networks, and long-distance campus links without excessive cost . In summary, a 10G optical module with a 40km range is affordable within the $100–$300 range, with the final price influenced by brand, optical quality, and additional features.
