10G DWDM SFP+ZR CH17-CH61 80km

Q: Types of 10G SFP+ Optical Modules

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

• 10G SFP+ Optical Module

This type represents the standard SFP+ module, functioning as an upgraded version of the 10G SFP module, and is currently the prevalent design in the market.

• BIDI SFP+ Optical Module

Employing wavelength division multiplexing, this module achieves a rate of 11.1Gbps with low power consumption. With two fiber ports designed for paired use, it reduces fiber requirements in data center network setups, thereby cutting construction costs.

• CWDM SFP+ Optical Module

Using coarse wavelength division multiplexing, this module is typically paired with single-mode fibers, conserving fiber resources and offering enhanced flexibility and reliability in network configurations with minimal power consumption.

• DWDM SFP+ Optical Module

Adopting dense wavelength division multiplexing, this module is utilized in long-distance data transmission with a maximum reach of 80km, featuring high speed, large capacity, and great scalability.

Q: Advantages of SFP+ Optical Modules

A:

SFP+ features a more compact form factor compared to X2 and similar packages (identical in size to SFP);

Directly interoperable with equivalent XFP, X2, and XENPAK modules;

Lower cost than XFP, X2, and XENPAK products.

Q: Differences and Connections between SFP+ and SFP

• A: Differences:

Protocol Specifications: SFP follows IEEE802.3 and SFF-8472, while SFP+ adheres to IEEE 802.3ae, SFF-8431, and SFF-8432;

SFP+ represents a more prevalent design in the industry.

• Connections:

Both SFP and SFP+ share the same physical dimensions;

Both SFP+ and XFP are 10G fiber modules and are interoperable with other types.
