CWDM4 is an optical transceiver device that transmits data using coarse wavelength division multiplexing (CWDM) technology. This technology enables the transmission of multiple signals over a single optical fiber by using different wavelengths of light. CWDM4 is commonly used for high-speed data transmission in data centers and other communication networks.
CWDM4 transmits data using four wavelengths: 1271 nm, 1291 nm, 1311 nm, and 1331 nm. These wavelengths are closely spaced to maximize the data capacity of the optical fiber. CWDM4 can transmit data at 100 Gbps (gigabits per second) over distances of up to 2 km (kilometers) using single-mode yarn.
CWDM4 is compatible with other CWDM technologies, such as CWDM8 and CWDM10. This means that CWDM4 can be used in conjunction with other CWDM transceivers to increase the total data capacity of an optical network. CWDM4 is compatible with various networking protocols, including Ethernet, Fibre Channel, and InfiniBand.
CWDM4 uses forward error correction (FEC) technology to reduce the number of data errors during transmission. FEC adds extra data to the transmitted signal that can be used to correct the mistakes that occur due to signal interference or other factors. CWDM4 supports two types of FEC: RS-FEC (Reed Solomon Forward Error Correction) and SD-FEC (Soft Decision Forward Error Correction).
CWDM4 supports multiple electrical data transmission standards, including 100GBASE-CWDM4 Ethernet and 4x25G InfiniBand. The electrical data transmission standards determine how the data is encoded and transmitted across the optical fiber. CWDM4 uses advanced electrical encoding techniques to ensure the transmitted data is accurate and reliable.
In conclusion, CWDM4 is a powerful optical transceiver device that uses CWDM technology to transmit high-speed data over long distances. CWDM4 has advanced features, including FEC technology and support for multiple electrical data transmission standards, making it highly reliable and versatile. As such, CWDM4 is an indispensable tool for data center managers and network engineers who need to build high-capacity, high-speed optical networks.
A CWDM4 transceiver is a module that combines a transmitter and a receiver, enabling the transmission of optical signals over optical fibers. The term ‘CWDM’ stands for Coarse Wavelength Division Multiplexing, a technology that allows multiple signals to be transmitted over a single fiber using different light wavelengths. A CWDM4 transceiver operates using four different wavelengths: 1271nm, 1291nm, 1311nm, and 1331nm. Each wavelength can transmit data at up to 25 Gbps, giving the overall module a total throughput of 100 Gbps.
Data centers require reliable, high-speed connectivity between servers, networking equipment, and storage devices. CWDM4 transceivers are a popular choice for data center deployments due to their high throughput, low power consumption, and cost-effectiveness. CWDM4 in data centers allows for consolidating multiple 25 Gbps links onto a single fiber pair, reducing the number of fibers required for connectivity. This saves the cost of yarn, simplifies cable management, and eases deployment.
CWDM4 transceivers comply with the CWDM4 Multi-Source Agreement (MSA), a set of common standards established by industry-leading companies to ensure interoperability between modules from different manufacturers. The MSA defines the optical specifications, mechanical dimensions, electrical parameters, and control interfaces of the CWDM4 module. Compliance with the MSA guidelines allows for the interchangeability of CWDM4 transceivers among different vendors, making it easier for customers to choose the best-fit product for their needs.

CWDM4 transceivers use single-mode fiber (SMF) as the transmission medium. SMF is an optical fiber with a small core and a narrow wavelength range that allows for high-speed, long-distance data transmission. The four wavelengths used in CWDM4 can be combined onto a single SMF by a passive multiplexer/demultiplexer, which separates the four wavelengths at the other end of the link using a similar device. SMF allows transmission distances up to 2 km (1.24 miles), making it suitable for intra-data center networking.
The distance that CWDM4 transceivers can transmit signals over optical fiber depends on the type of fiber used. CWDM4 is designed to work with SMF, with a limited maximum transmission distance of 10 km (6.21 miles). To extend the reach beyond this limit, amplifiers or repeaters can be used, although this will increase the complexity and cost of the system. CWDM4 is unsuitable for long-haul networks since it cannot transmit signals over distances greater than 10 km without additional equipment.
Parallel Single-Mode Fiber Four-Lane (PSM4) is another popular transceiver type for 100 Gbps transmission over four fibers. The difference between CWDM4 and PSM4 is the type of fiber used. PSM4 uses four separate single-mode fibers to transmit data, while CWDM4 uses one single-mode fiber for data transmission. CWDM4 requires a multiplexer/demultiplexer, whereas PSM4 requires four cables. CWDM4 is more cost-effective and straightforward, while PSM4 provides longer transmission distances but has a higher cost and complexity. Choosing which one to use depends on the specific needs of the network.
Data centers are the backbone of our ever-growing digital world. These centers house countless servers, switches, and storage devices that store, process, and manage data. Therefore, it is crucial to implement efficient and effective optical interconnects between these devices. CWDM4, or coarse wavelength division multiplexing 4, is a visual technology that helps achieve this goal. It is a four-channel multiplexing technology that operates in the 1310nm wavelength range and is specifically designed for data center interconnectivity.
CWDM4 provides a distinct advantage over traditional optical technologies such as multimode and single-mode fiber.

The CWDM4 100G transceiver stands out from other 100G transceivers due to its unique design and features. It uses four channels, each operating at a wavelength range of 1270nm to 1330nm. This enables it to transmit data over a single-mode fiber optic cable up to a distance of 2km using duplex LC connectors. On the other hand, the LR4 100G transceiver uses four lanes, each transmitting data at a wavelength of 1310nm, which limits its reach to only up to 10km over single-mode fiber optic cables.
The main difference between CWDM4 and CLR4 100G transceivers is their reach and cost-effectiveness. While CWDM4 can transmit data up to 2km using duplex LC connectors, CLR4 can transfer data up to 10km using duplex LC or single-mode MPO/MTP connectors. Additionally, CLR4 is more expensive than CWDM4 due to its more extended reach and complex design, which requires additional optical components.
QSFP28 optical transceivers are used for high-speed data transmission in data centers. They provide a higher data rate of up to 200G and a more extended reach of up to 40km over single-mode fiber optic cables. However, CWDM4 100G transceivers are more cost-effective for shorter distances and offer more straightforward connectivity options via duplex LC connectors.
Parallel Single-Mode 4 (PSM4) and other modules like PAM4 and NRZ400G are different 100G transceivers that provide high-speed data transmission over single-mode fiber optic cables. However, PSM4 requires eight fibers for connectivity, while CWDM4 only requires two fibers using duplex LC connectors. PSM4 and other modules don’t support long distances like CWDM4, which can transmit up to 2km over a single-mode fiber optic cable.
Single-mode fiber optic cables with duplex LC connectors are widely used for high-speed data transmission in data centers. However, they are limited in distance, which makes them unsuitable for long-distance communication. CWDM4 100G transceivers offer a cost-effective solution for shorter lengths of up to 2km over single-mode fiber optic cables. They also require more straightforward connectivity options via duplex LC connectors, making them easier to install and maintain.
