10G DWDM SFP+ CH17-CH61 120km

Q: Types of 10G SFP+ Optical Modules

A: Conventionally, SFP+ optical modules are categorized based on their practical applications. Common types include 10G SFP+, BIDI SFP+, CWDM SFP+, and DWDM SFP+.

10G SFP+ Optical Module

This type of module serves as a standard SFP+ optical module, effectively an upgraded version of the 10G SFP module, and is the prevailing design in the current 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, enabling a reduction in the number of fibers required during data center network construction, thus lowering the overall cost.

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, along with low power consumption.

DWDM SFP+ Optical Module

Adopting dense wavelength division multiplexing, this module is primarily used for long-distance data transmission, capable of reaching distances up to 80km, characterized by high speed, large capacity, and strong scalability.

Q: Advantages of SFP+ Optical Modules

A: ① SFP+ features a more compact form factor compared to X2 and similar packages (matching the size of SFP);

② It can directly interface with equivalent XFP, X2, and XENPAK modules;

③ It comes at a lower cost than XFP, X2, and XENPAK products.

Q: Differences and Connections between SFP+ and SFP

A: (1) Differences:

① Protocol specifications: SFP follows IEEE802.3 and SFF-8472, whereas SFP+ adheres to IEEE 802.3ae, SFF-8431, and SFF-8432;

② SFP+ represents a more mainstream design.

(2) Connections:

① SFP and SFP+ share identical physical dimensions;

② Both SFP+ and XFP are 10G fiber modules that are interoperable with other types.
