What are the different types of sfp28?
SFP28 transceivers are typically categorized based on their transmission speed and reach. Common types include SFP28 SR (short range) for distances up to 100 meters over multi-mode fiber, SFP28 LR (long range) for distances up to 10 kilometers over single-mode fiber, and SFP28 ER (extended range) for longer distances. Additionally, there are SFP28 DAC (direct attach copper) for short-distance connections within a data center and SFP28 AOC (active optical cable) for high-speed data transmission over longer distances. Each type of SFP28 transceiver is designed for specific networking requirements and applications.
SFP28 Copper Direct Attach Cable
SFP28 Copper Direct Attach Cable is a type of Small Form-Factor Pluggable (SFP) transceiver module that supports data rates of up to 25 Gbps. There are different types of SFP28 transceivers available, each designed for specific networking needs. The most common types of SFP28 transceivers include:
1. SFP28 SR (Short Range): This type of transceiver is designed for short-distance connections within a data center, typically up to 100 meters over multimode fiber.
2. SFP28 LR (Long Range): This transceiver is used for longer-distance connections, up to 10 kilometers over single-mode fiber.
3. SFP28 ER (Extended Range): This type of transceiver supports even longer distances, up to 40 kilometers over single-mode fiber.
4. SFP28 CWDM: This transceiver is designed for coarse wavelength division multiplexing (CWDM) applications, allowing for multiple channels over a single fiber.
5. SFP28 PSM4 (Parallel Single Mode): This transceiver uses parallel single-mode fiber to achieve higher data rates over short distances.
6. SFP28 AOC (Active Optical Cable): This type of transceiver uses optical fiber cables with integrated transceivers for high-speed connections.
It's important to note that advancements in technology may lead to the introduction of new types of SFP28 transceivers or improvements in existing ones to meet the evolving needs of high-speed networking environments.
SFP28 Optical Transceiver Module
The SFP28 Optical Transceiver Module is a type of small form-factor pluggable transceiver that supports data rates up to 28 Gbps. There are several different types of SFP28 transceivers available, each designed for specific applications and network requirements. Some common types of SFP28 transceivers include:
1. SR (Short-Range): Designed for short-distance transmission within data centers, typically up to 100 meters over multimode fiber.
2. LR (Long-Range): Intended for longer-distance transmission, typically up to 10 kilometers over single-mode fiber.
3. ER (Extended Range): Offers even longer reach than LR transceivers, typically up to 40 kilometers over single-mode fiber.
4. CWDM (Coarse Wavelength Division Multiplexing): Allows for multiple wavelengths to be transmitted over a single fiber, increasing network capacity.
5. DWDM (Dense Wavelength Division Multiplexing): Provides even higher capacity by using more closely spaced wavelengths for transmission.
The latest trend in SFP28 transceivers is the development of higher-speed models to support emerging technologies such as 5G networks and high-performance computing applications.
