This makes it suitable for long-distance connections within data centers or for connecting data centers over longer distances.
The QSFP28-LR4 module offers high performance and reliability, enabling efficient and stable transmission of data at high speeds. It is commonly used in applications where long-range connectivity is required, such as interconnecting data centers, metro networks, and long-haul transmissions.
It's important to note that technology is constantly evolving, and new types of QSFP28 modules may emerge in the future. Therefore, it's always recommended to stay updated with the latest industry trends and consult with experts to ensure you have the most up-to-date information on the types of 100G QSFP28 modules available.
QSFP28-ER4: Extended-range single-mode fiber optic module.
The QSFP28-ER4 is one of the types of 100G QSFP28 modules available in the market. It is specifically designed for extended-range applications using single-mode fiber optic cables. The "ER" in QSFP28-ER4 stands for "Extended Range," indicating its capability to transmit data over longer distances.
The QSFP28-ER4 module utilizes four wavelengths (or colors) of light to transmit data, with each wavelength carrying 25Gbps of data. This results in a total data transmission capacity of 100Gbps. The module is compatible with the QSFP28 form factor, which is widely used for high-speed data transmission in data centers and telecommunications networks.
The QSFP28-ER4 module is typically used for long-distance applications, where the transmission distance can range from 10km to 40km or more, depending on the quality of the fiber optic cable and other factors. It is commonly used in applications such as long-haul telecommunications, metro networks, and data center interconnects.
It is important to note that technology is constantly evolving, and new types of 100G QSFP28 modules may become available in the future. These modules may offer improved performance, higher data transmission speeds, or longer transmission distances. Therefore, it is always advisable to consult with a trusted supplier or manufacturer to get the latest information on the types of 100G QSFP28 modules available in the market.
QSFP28-CWDM4: Coarse wavelength division multiplexing module for data centers.
The QSFP28 (Quad Small Form-factor Pluggable 28) is a high-speed transceiver module commonly used in data centers for high-density and high-bandwidth applications. It supports data rates up to 100Gbps and is designed to work with various network protocols such as Ethernet, InfiniBand, and Fibre Channel.
One of the types of QSFP28 modules is the QSFP28-CWDM4, which stands for Coarse Wavelength Division Multiplexing. This module utilizes wavelength division multiplexing technology to transmit and receive data over four different wavelengths. Each wavelength carries a separate data stream, allowing for increased data capacity and transmission efficiency.
The QSFP28-CWDM4 module is particularly suitable for data centers as it enables the consolidation of multiple connections into a single fiber strand. This helps reduce the complexity of cabling infrastructure and allows for higher density deployments. It is also cost-effective compared to other high-speed transceiver options.
The QSFP28-CWDM4 module is compatible with single-mode fiber and has a reach of up to 2 kilometers. It operates at 1310nm wavelength and supports 4x25Gbps data transmission. This makes it ideal for short to medium-range applications within data centers.
It is worth noting that technology is constantly evolving, and new types of QSFP28 modules may emerge in the future. These advancements may include higher data rates, longer reach capabilities, and improved power efficiency. Therefore, it is always important to stay updated with the latest developments in the field of QSFP28 transceiver modules.
