10G SFP+ ER 1550nm 40km

Q: What is a 10G SFP+ module?

A: The SFP+ module evolves from the small form-factor pluggable (SFP) module and serves as a high-speed transceiver designed to facilitate data transmission rates up to 10 Gbps. This advanced iteration is broadly compatible with numerous network equipment vendors and highly effective in telecommunication and data communication applications, rendering it ubiquitous in modern networks.

Q: Types of 10G SFP+ Optical Modules

A: Conventionally, SFP+ optical modules are categorized based on practical applications, with common types including 10G SFP+, BIDI SFP+, CWDM SFP+, and DWDM SFP+. For further details, please click on the 10G SFP+ Transceiver Modules category.

Q: What is the difference between 10G SFP+ and C/DWDM SFP+ modules?

A: The primary distinctions between 10G SFP+ and 10G Coarse/Dense Wavelength Division Multiplexing (C/DWDM) SFP+ modules lie in their functionalities and applications:

1. 10G SFP+ Modules: These modules act as standard 10 Gigabit Ethernet transceivers for data transmission over medium to short distances. Operating at a single wavelength, they are typically employed in conventional Ethernet networks, with transmission ranges reaching 300 meters on multi-mode fiber and up to 40 kilometers on single-mode fiber.
2. 10G C/DWDM SFP+ Modules: Leveraging C/DWDM technology, these modules enable the concurrent transmission of multiple wavelengths of light over a single fiber. While CWDM supports fewer channels across wider wavelength spacings, DWDM offers more channels within narrower spacings. Designed for long-distance transmission, C/DWDM SFP+ modules boost network capacity by multiplexing multiple signals onto a single pair of fibers.
