    The International Standard of 25G SFP28 Transceiver, and the Introduction of Each Type -Etern

    In the ever-evolving world of high-speed telecommunications and data networking, the 25G SFP28 transceiver has emerged as a vital component for meeting the increasing demand for faster data transmission. With the growing need for efficient communication networks, understanding the international standards and different types of SFP28 transceivers is crucial for both manufacturers and businesses.

    1. What is the 25G SFP28 Transceiver?

    The 25G SFP28 transceiver is a small form-factor pluggable (SFP) transceiver used for optical and electrical communications, providing data rates of up to 25 gigabits per second (Gbps). It is an upgraded version of the SFP+ transceiver, designed to meet the growing bandwidth needs of data centers, cloud services, and telecommunications networks.

    SFP28 transceivers are commonly used in high-speed Ethernet, fiber-optic, and telecom transmission networks. They are known for their compact design, high efficiency, and reliability, making them ideal for modern data center and enterprise applications.

    2. International Standards of 25G SFP28 Transceivers

    The international standards for 25G SFP28 transceivers are governed by organizations such as the IEEE (Institute of Electrical and Electronics Engineers) and Mellanox Technologies. The most important specifications and standards for SFP28 transceivers include:

    • IEEE 802.3by: Defines the 25G Ethernet standard, setting requirements for transmission rates, power consumption, and physical layer specifications.
    • SFF-8636: Describes the SFP28 form factor and the interface standards, ensuring compatibility across different manufacturers and ensuring the transceivers can be used universally in network systems.
    • QSFP28: The QSFP28 is often used in parallel with the SFP28, offering similar performance in larger form factors, and supports more advanced applications such as 100G Ethernet.

    These standards ensure that 25G SFP28 transceivers are interoperable across various devices and manufacturers, ensuring seamless integration in modern network systems.

    3. Types of 25G SFP28 Transceivers

    There are different types of 25G SFP28 transceivers, each designed for specific applications and transmission distances. Here’s an overview of the common types:

    1. 25G SFP28 SR (Short Range)

    • Application: Typically used for short-distance transmission within data centers or on fiber-optic networks.
    • Wavelength: Usually operates at a wavelength of 850nm.
    • Distance: Can support transmission distances up to 100 meters over multimode fiber (MMF).
    • Use Case: Ideal for high-speed connections between switches and servers in data centers.

    2. 25G SFP28 LR (Long Range)

    • Application: Designed for long-distance transmission in wide-area networks (WAN) or between data centers.
    • Wavelength: Works with a 1310nm wavelength.
    • Distance: Can support distances of up to 10 kilometers over single-mode fiber (SMF).
    • Use Case: Perfect for linking large data centers or connecting to telecom infrastructure.

    3. 25G SFP28 ER (Extended Range)

    • Application: Used for extended-range applications where distances exceed the capabilities of LR modules.
    • Wavelength: Operates at a wavelength of 1550nm.
    • Distance: Can support distances of up to 40 kilometers over single-mode fiber (SMF).
    • Use Case: Often used in telecom and ISP networks for city-wide or regional fiber-optic connections.

    4. 25G SFP28 DAC (Direct Attach Copper)

    • Application: Used for high-speed copper cable connections between network devices, offering lower power consumption and cost-effective solutions.
    • Distance: Typically supports distances up to 5 meters.
    • Use Case: Common in enterprise environments for server-to-switch connections or between devices within a rack.
