In the digital age, the demand for higher bandwidth has been constantly increasing. With the surge of data intensive applications such as cloud computing, high-definition video streaming, and big data analysis, traditional low-speed optical transceivers are no longer able to meet the requirements. The development of the 100G QSFP28 BIDI ZR4 is to meet the demand for high-speed data transmission of 100 gigabits per second.

The standardized appearance of QSFP28 (Quad Small Form Factor Pluggable 28) provides a compact and efficient method for achieving high-speed optical interfaces. QSFP28 modules typically have lower power consumption and better energy efficiency compared to older 100G modules, making them suitable for high-density deployment needs in data centers.

BIDI allows bidirectional data transmission through a single optical fiber, which is different from traditional four channel (four wavelength) modules. Data is transmitted through dual wavelengths, and sending and receiving are done through different wavelengths, enabling bidirectional communication on a single optical fiber

Thereby improving the efficiency of fiber optic usage.

The ZR4 module uses single-mode fiber to transmit data, which is suitable for long-distance transmission due to its low signal loss and large bandwidth, especially for transmission needs from 80km to 100km.

The CL100GQBD80 of C-LIGHT is designed specifically for commercial grade 80km optical communication applications. The single-mode fiber has low transmission loss and is suitable for long-distance communication. The module includes a 4-channel optical transmitter, a 4-channel optical receiver, and a module management block, including 2-wire serial I/O. The optical signal is multiplexed onto single-mode fiber through industry standard LC connectors.

As a high-performance optical module, the C-LIGHT 100G QSFP28 BIDI ZR4 provides high bandwidth while having low power consumption, which helps reduce power consumption and cooling needs in data centers

The C-LIGHT 100G QSFP28 BIDI ZR4 has a wide range of application scenarios.

In data centers, it plays a crucial role.Thanks to cloud computing, virtualization, and large-scale data storage, the data traffic within data centers has experienced exponential growth. The 100G QSFP28 BIDI ZR4 enables high-speed interconnection between servers, switches, and storage systems. It ensures fast and efficient data transmission, minimizes latency, and maximizes the overall performance of data center infrastructure.

For telecommunications networks, it is highly suitable for both urban and long-distance transmission. In metropolitan area networks, it can support high-speed communication between different network nodes in cities or regions. In long-distance transmission, it can transmit large amounts of data over long distances, such as between different cities or countries. This is particularly important for telecommunications operators who need to transmit voice, video, and data traffic over their extensive networks.

The enterprise network also benefits from C-LIGHT 100G QSFP28 BIDI ZR4. As enterprises increasingly rely on high-speed data communication for business operations, whether it's video conferencing, file sharing, or running enterprise level applications, this transceiver can provide the necessary high bandwidth connectivity to connect different offices or branches together, ensuring seamless communication and efficient business processes.

Long distance performance and cost-effectiveness of 80 kilometers

C-LIGHT adopts a self-made 100G QSFP28 BIDI ZR4 80km optical module, using a single fiber, and is used in conjunction with the C-LIGHT CLS6865-56YC 100G port switch, providing a total link budget of 30dB. Implemented 100G P2P 80KM data communication from point A to point B.

In this scheme, the 100G QSFP28 BIDI 80km ZR4 transceiver of C-LIGHT can provide a maximum transmit optical power of 5dBm per channel and ensure a sensitivity of -28dBm per channel, which can provide a total link budget of over 30dB per channel for this scheme.

The 100G QSFP28 BIDI ZR4 itself is a powerful component. The 100G QSFP28 BIDI ZR4 module supports bidirectional transmission technology and long-distance support. It can support high-speed data transmission of 100 gigabits per second, which is crucial for modern data intensive applications. It is suitable for long-distance and metropolitan area network applications, and can achieve reliable data transmission over long distances. This makes it highly suitable for use in data centers, telecommunications networks, and enterprise networks that require seamless and high-speed data communication.
