Introduction: What is a Quad Small Form Factor?
A Quad Small Form Factor (qsfp) is a small form factor pluggable module that has four lanes of 100Gbps or four lanes of 25Gbps. The qsfp was originally developed by the InfiniBand Trade Association in 2010 as a standard for 100 gigabit Ethernet over copper cabling. The qsfp was later adopted by the Optical Internetworking Forum (OIF) in 2011 as an optical transceiver module for data rates of up to 400 gigabits per second. QSFP has a data rate of 25Gbps and it can be used in a variety of applications such as 100G QSFP28, 40G QSFP+, 400G QSFP-DD.
The qsfp is a compact, hot-pluggable, and optic transceiver module. It is designed to be used in data center applications for high-speed data transmission. The qsfp can be used for 100Gbps or 25Gbps speeds and has a compact factor.
What are the Advantages of QSFPS?
The QSFP+ is a hot-pluggable, high-speed, low-power consumption optical module. It is designed for use in data centers and enterprise networks.
The QSFP+ has many advantages over the SFP+ module. The QSFP+ has a higher bandwidth, lower power consumption, higher density, and easier installation. It also provides more diversified models and cost-effective choices.
- High bandwidth: The QSFP+ is a hot-pluggable, high-speed optical module that supports data rates up to 100 Gb/s.
- Low power consumption: The QSFP+ consumes less power than the previous generation of modules because it uses an advanced low-power serializer/deserializer (SerDes) design with a reduced number of components per lane and a more efficient clock tree.
- High density: The QSFP-100G-SR4 adopts an MTP-12 interface which is suitable for high-density applications.
- easy installation: The QSFP module is equipped with a large pull ring, which is very easy to plug and unplug.
How Does QSFPS Work?
The QSFP has a 4x25G interface and a 4x10G interface. The 4x25G interface is used to transmit data at 25 Gbps, while the 4x10G interface is used to transmit data at 10 Gbps. The Breakout mode can be selected by the user according to their needs.
The QSFP28 supports four lanes of NRZ format and has an input clock frequency range of 1 MHz to 25 MHz. The principle of QSFPS is to use the differential signal transmission mode to transmit data between two devices. The first device has 4x25g ports, while the second device has 4x10g ports. The first device sends differential signals to the second device through four lanes of NRZ， and then the second device receives them and converts them into NRZ signals with different frequencies.
The QSFP28 is a high-speed, high-density, low-power, and low-cost parallel optical switch. It can be used in the following applications:
- Optical networks
- Data centers
- Metro politician
