# What are the types of SFP?

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:

1\. SX (Short-Range):

Supports short distances, typically using multimode fiber.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://phantanloc.gitbook.io/locpt_wiki/homepage/2.it-cntt/ict/what-are-the-types-of-sfp.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
