SFP vs QSFP Transceivers – X Differences to Know

 

QSFP-transceiver

SFP (small form factor pluggable) and QSFP (quad form factor pluggable) are two transceiver modules commonly used in optical communication applications. Although they’re both form-factor pluggable devices (which means you can insert and remove them from a network device without powering it off), both modules have some differences.

In this article, we will discuss these differences as well as where you can buy SFP and QSFP modules at affordable prices.

1. Form Factor

The primary difference between SFP and QSFP is in their physical size and shape, referred to as form factor. SFP only has a single port for data transmission and receiving, allowing a single fiber connection. QSFP transceiver has multiple ports for receiving and transmitting data, allowing parallel fiber connections.

2. Data Rates

The data rate tells the amount of data these modules support per second. SFP transceivers can support up to 10 GB/s (gigabytes per second) of data— therefore, they are used in applications like Ethernet, SONET/SDH, etc. On the other hand, QSFP modules can support up to 40–100 GB/s, allowing higher data rates.

You can buy QSFP for high-performance computing, cloud computing, and data center operations to meet high bandwidth requirements.

3. Applications

QSFP modules can handle more data and faster connections than SFP modules which is why both have different applications. SFP modules are good for lower speeds, like when you want to connect switches, routers, and servers in your office network, or in a small or medium-sized data center. They can also work for some telecom applications.

QSFP modules are for higher speeds, like when you have a lot of data to move around in a big data center, when you need to link up computers that do heavy calculations, or when you need to store and access data in a SAN (storage area network).

4. Fiber Type

There are mainly two types of fiber such as single-mode and multimode fiber. Both SFP and QSFP can support any type of fiber type, but deliver different results. QSFP modules have a larger form factor, allowing them to form several fiber connections and support parallel links.

This way, these modules can transmit data over multiple fiber strands at the same time, increasing the data capacity and scalability.

 

5. Price

Due to their size and data rate, SFP and QSFP modules vary in price. SFPs are more cost-effective and provide an affordable solution for networking deployments without high demands. QSFP modules are more expensive but they offer a robust and reliable solution for handling higher data.
