What is the length of qsfp28?
The length of a QSFP28 (Quad Small Form-factor Pluggable 28) module is typically around 100 millimeters.
QSFP28 Overview and Specifications
The length of QSFP28, which stands for Quad Small Form-factor Pluggable 28, refers to the physical dimensions of the module. QSFP28 is a high-speed transceiver module used in data communication applications, primarily for Ethernet and Fibre Channel networks. It is designed to support data rates of up to 100 Gbps.
The dimensions of a QSFP28 module are standardized to ensure compatibility and interoperability across different networking equipment. The length of a QSFP28 module is approximately 18 millimeters (mm). However, it is important to note that this length does not include the length of the connectors or the pull-tab. Including the connectors and the pull-tab, the overall length of a QSFP28 module is typically around 84 mm.
It is worth mentioning that the length of QSFP28 modules has remained relatively consistent since its introduction. However, it is always recommended to refer to the specific datasheet or manufacturer's specifications for the most accurate and up-to-date information regarding the length of a QSFP28 module.
As technology advances, there may be future developments in QSFP28 modules that could potentially impact their length. However, as of the latest information available, the approximate length of a QSFP28 module is 18 mm, excluding connectors and pull-tabs, and around 84 mm including them.
QSFP28 Electrical Interface
The QSFP28 (Quad Small Form-factor Pluggable 28) is a high-speed electrical interface used in data communication applications. It is designed to support data rates of up to 100 gigabits per second (Gbps) and is commonly used in data centers and high-performance computing environments.
In terms of length, the QSFP28 module itself is relatively small, measuring approximately 18.35mm in height, 56.5mm in width, and 33.6mm in depth. This compact form factor allows for high-density interconnectivity, enabling efficient use of space within networking equipment.
However, it is important to note that the length of the QSFP28 module does not directly refer to the maximum reach or distance it can transmit signals. The transmission distance is dependent on the type of optical or copper cable used with the QSFP28 module.
For optical cables, the QSFP28 module can support various types of fiber optic cables, such as single-mode or multi-mode fibers, which have different transmission distances. Single-mode fibers typically offer longer transmission distances, reaching up to 10 kilometers or more, while multi-mode fibers have shorter reach, typically up to a few hundred meters.
When it comes to copper cables, the QSFP28 module supports various lengths, including passive copper cables up to 5 meters and active copper cables that can reach up to 15 meters or more.
It is worth mentioning that advancements in technology and the development of new cable types may result in increased transmission distances for QSFP28 modules. Therefore, it is always recommended to refer to the latest specifications provided by the manufacturers for accurate information on the maximum reach of QSFP28 modules.
QSFP28 Applications and Industry Adoption
The length of QSFP28 refers to the physical dimensions of the QSFP28 transceiver module. QSFP28 stands for Quad Small Form-Factor Pluggable 28, where 28 represents the module's data rate of 28 gigabits per second (Gbps).
The QSFP28 transceiver is widely used in high-speed networking applications, primarily in data centers and telecommunications networks. It supports various protocols, including Ethernet, Fibre Channel, InfiniBand, and SONET/SDH. The module is designed to provide high-density and high-bandwidth connectivity, making it suitable for applications that require fast data transfer rates.
In terms of length, the QSFP28 module typically measures around 18 millimeters (mm) in width, 72 mm in length, and 8.5 mm in height. These dimensions make it compact and allow for efficient use of space in networking equipment.
As for the latest point of view, the industry adoption of QSFP28 has been growing rapidly due to the increasing demand for higher data rates and bandwidth. With the rise of cloud computing, big data, and streaming services, there is a need for faster and more efficient networking solutions. QSFP28 addresses these requirements by offering 100 Gbps data rates and supporting emerging technologies like 400 Gigabit Ethernet.
Furthermore, QSFP28 modules are backward compatible with previous QSFP form factors, such as QSFP+ and QSFP28, which allows for easy integration into existing network infrastructures. This compatibility, along with its small form factor, has contributed to the widespread adoption of QSFP28 in the industry.
In conclusion, the length of QSFP28 refers to its physical dimensions, which are approximately 18 mm in width, 72 mm in length, and 8.5 mm in height. This compact module has gained significant industry adoption due to its high data rates, compatibility, and suitability for various high-speed networking applications.
