OSFP vs QSFP-DD
=====================
Введение
——————–
The rapid growth of data centers and the need for faster and more efficient networking solutions has led to the development of new optical transceiver form factors. В этой статье, we will compare two such form factors: OSFP and QSFP-DD. We will discuss their differences in terms of size, power consumption, и скорость передачи данных.
Size Comparison
——————–
OSFP, short for Octal Small Form-factor Pluggable, is a transceiver form factor that was specifically designed for high-speed Ethernet applications. It is slightly larger than the traditional QSFP28 module and has dimensions of approximately 96mm x 108mm x 20mm. С другой стороны, КСФП-ДД, which stands for Quad Small Form-factor Pluggable-Double Density, is an enhanced version of QSFP28 that allows for twice the number of high-speed electrical lanes. It is slightly larger than OSFP with dimensions of approximately 90mm x 18.35mm x 13.35mm.
Потребляемая мощность

When it comes to power consumption, QSFP-DD has a slight advantage over OSFP. This is because QSFP-DD modules require lower voltage levels for operation, resulting in lower power consumption. The reduced power consumption of QSFP-DD makes it a preferred choice for data centers aiming to reduce their overall power usage. Однако, it is worth noting that both OSFP and QSFP-DD modules are designed to be power-efficient compared to their predecessors.
Data Rates
——————–
Both OSFP and QSFP-DD form factors support high data rates, allowing for faster and more efficient data transmission. OSFP modules have a data rate of up to 400 Гигабит в секунду (Гбит/с), making them suitable for applications that require high bandwidths. С другой стороны, QSFP-DD modules support data rates of up to 800 Гбит/с, making them ideal for even more demanding applications. The higher data rate of QSFP-DD enables data centers to handle increasing workloads and bandwidth requirements.
Заключение
——————–
В итоге, OSFP and QSFP-DD are two competing transceiver form factors that offer high-speed and energy-efficient solutions for data centers. While OSFP is slightly larger in size, QSFP-DD provides a higher data rate and lower power consumption. The choice between OSFP and QSFP-DD ultimately depends on the specific requirements and goals of the data center.
