10G CWDM XFP ER 1470nm 80km

Q: What is the difference between 10G SFP+ and 10G XFP optical modules?

A:

• The 10G SFP+ optical module is an upgraded version of the SFP module, based on the SFP form factor, whereas the 10G XFP optical module adheres to the XFP packaging standard.
• The 10G SFP+ optical module has a smaller physical size compared to the 10G XFP module, thus fulfilling the volume requirements for high-density circuit boards. Conversely, the 10G XFP module, being larger, facilitates better heat dissipation.
• The 10G SFP+ module has migrated functions such as signal modulation, serialization/deserialization, MAC, clock and data recovery (CDR), and electronic dispersion compensation (EDC) from the module to the motherboard card. The 10G XFP module still retains these functions onboard. Therefore, when a switch/router’s motherboard does not integrate the functionalities required by 10G SFP+ modules, a 10G XFP module is used to fill the gap.
• The 10G SFP+ module is less expensive than the 10G XFP module and is interoperable with other types of 10G optical modules.
• For 10G communications, direct attach cables (DACs) can be employed, which feature two built-in 10G SFP+ optical module ends, eliminating the need to separately purchase two 10G SFP+ modules – an option not available with 10G XFP.
• On switches, a 10G SFP+ port can accept SFP modules, whereas a 10G XFP port is compatible solely with 10G XFP optical modules.

Q: What is a 10G XFP optical module?

A: A 10G XFP optical module is a compact, pluggable transceiver module designed for achieving data transmission rates of 10Gbps. The XFP (10 Gigabit Small Form Factor Pluggable) format is smaller than earlier XenPAK, X2, and XenPAK modules, suited for high-speed data communication applications such as in data centers and metropolitan networks.

Q: What are the common types of 10G XFP optical modules?

A: Common types of 10G XFP optical modules include 10GBASE-SR (multimode short-range), 10GBASE-LR (single-mode long-range), 10GBASE-ER (enhanced long-range), 10GBASE-ZR (ultra-long-range), and 10GBASE-DWDM (Dense Wavelength Division Multiplexing).

Q: What is the transmission distance range for 10G XFP optical modules?

A: The transmission distance depends on the module type. For instance, the multimode 10GBASE-SR version typically supports up to 300 meters, the single-mode 10GBASE-LR can reach 10 kilometers, 10GBASE-ER extends up to 40 kilometers, and 10GBASE-ZR can achieve up to 80 kilometers or more.

Q: What is the power consumption of a 10G XFP optical module?

A: The typical power consumption of a 10G XFP optical module ranges around 1-3 watts, although this can vary depending on the manufacturer’s design and module features.
