SFP-10G-BX10 vs BX20 vs BX40 vs BX60 vs BX80 vs BX100: Guia completo sobre transceptores SFP+ BiDi de 10G

Introdução

When upgrading a fiber network to 10 Gigabit Ethernet, many engineers face the same question:

Should I choose SFP-10G-BX10, BX20, BX40, BX60, BX80, or BX100?

All six modules belong to the Transceptor SFP+ BiDi de 10 Gbps family and use WDM technology to transmit and receive data over a single strand of single mode fiber. However, each model is optimized for different transmission distances and network environments.

In this guide, we compare the entire BX series and explain how to choose the correct module for your project.

What Is a 10G BiDi SFP+ Transceiver?

A Transceptor SFP+ BiDi de 10 Gbps uses Wavelength Division Multiplexing (WDM) technology to transmit and receive optical signals on different wavelengths through a single fiber.

Compared with traditional duplex SFP+ modules:

Vantagens

• Uses only one fiber strand
• Reduces cabling costs
• Saves fiber resources
• Simplifies installation
• Ideal for limited fiber environments

For many enterprise and telecom networks, a Transceptor de 10 G de fibra única can reduce fiber infrastructure requirements by up to 50%.
