10G DWDM SFP+ CH17-CH61 100km

Q: Types of 10G SFP+ Optical Modules

A: Conventionally, SFP+ optical modules are classified based on their practical applications, with common types including standard 10G SFP+, BIDI SFP+, CWDM SFP+, and DWDM SFP+.

10G SFP+ Optical Module

This type of module serves as a general-purpose SFP+ module and can be seen as an upgraded version of the 10G SFP module, representing the mainstream design in the market.

BIDI SFP+ Optical Module

Employing wavelength division multiplexing technology, this module achieves a rate of up to 11.1Gbps with low power consumption. Featuring two fiber ports, it is typically used in pairs, reducing the amount of fiber required in data center network deployments and thereby lowering construction costs.

CWDM SFP+ Optical Module

Utilizing coarse wavelength division multiplexing, this module is commonly paired with single-mode fibers, conserving fiber resources and offering greater flexibility and reliability in networking with low power consumption.

DWDM SFP+ Optical Module

Adopting dense wavelength division multiplexing, this module is often used for long-distance data transmission, with a maximum transmission distance of up to 80km, characterized by high speed, large capacity, and strong expandability.

Q: SFP-10G-LRM vs. SFP-10G-LR 10Gigabit Optical Modules: How to Choose?

A: The SFP-10G-LR 10Gigabit optical module is suitable for remote communications up to 10 kilometers, such as interconnecting buildings in large campuses and constructing metropolitan area networks (MANs). The SFP-10G-LRM, besides supporting multimode transmission, can also accommodate single-mode transmission, where no optical saturation occurs. The SFP-10G-LRM can transmit up to 300 meters. Therefore, for transmissions within 300 meters, the SFP-10G-LRM provides a more economical and effective solution. For distances between 300 meters and 2 kilometers, the SFP-10G-LRM2 is a better fit than the SFP-10G-LR, as it offers a lower price point for the same transmission range. For distances ranging from 2 to 10 kilometers, the SFP-10G-LR is the preferred choice.

Note: The SFP-10G-LRM2 has a maximum transmission distance of 2 kilometers over single-mode fiber, making it suitable for short-range local area network connections.
