What are the types of SFP?

Small Form-Factor Pluggable (SFP) modules can vary based on their intended use. Common types include:

1. SX (Short-Range):

Supports short distances, typically using multimode fiber.

2. LX (Long-Range):

Designed for longer distances, often used with single-mode fiber.

3. BX (Bi-directional):

Sends and receives signals on a single fiber strand, using different wavelengths for upstream and downstream.

4. ZX (Extended Range):

Offers extended reach compared to standard modules, suitable for long-distance connections.

5. CWDM/DWDM (Wavelength Division Multiplexing):

Allows multiple wavelengths to be transmitted over a single fiber, increasing capacity.

6. SR (Short-Range) and LR (Long-Range) Bidi SFPs:

Bi-directional modules for short and long distances, respectively.

Choosing the right SFP depends on factors like distance requirements, fiber type, and network specifications. In Fiber-to-the-Home (FTTH) installations, Small Form-Factor Pluggable (SFP) modules can vary based on their intended use. Common types include:
