It adheres to the 40GBase-SR-BiDi standard, making it compatible with a wide range of networking equipment and protocols. This compatibility ensures seamless integration into existing network infrastructures.
  • Multi-mode Fiber and Wavelength: The transceiver module utilizes multi-mode fiber (MMF) for data transmission, offering versatility in deployment scenarios. With a wavelength of 850nm, the QSFP-40G-BD-RX leverages the optimal range for multi-mode fiber, ensuring reliable and high-performance connectivity.
  • Transmission Distance: Cisco's QSFP-40G-BD-RX is designed to cover a transmission distance of up to 150 meters. This makes it suitable for various short to medium-range applications within data centers, enterprise networks, and other environments requiring high-speed connectivity.
  • LC Connector: The transceiver module features an LC (Lucent Connector) for fiber optic connections. LC connectors are known for their compact size and reliable performance, making them a standard choice in the networking industry. The LC connector in the QSFP-40G-BD-RX ensures a secure and efficient optical connection.

Applications and Use Cases

Its ability to handle large volumes of data at high speeds makes it an invaluable component in HPC environments, contributing to faster data processing and analysis.

A Breakthrough in Fiber Optic Technology

The QSFP-40G-BD-RX is a type of transceiver module developed by Cisco that operates at 40 Gbps and uses bi-directional fiber optic technology to transmit and receive data. This transceiver is designed to work with single-mode fiber optic cables and is used primarily in data center and networking environments to connect switches, routers, and servers.

The breakthrough in fiber optic technology that is used in the QSFP-40G-BD-RX transceiver is the use of bi-directional transmission. Bi-directional fiber optic technology allows for the simultaneous transmission of data in both directions over a single strand of fiber optic cable. This is achieved through the use of a special type of optical multiplexer/demultiplexer that separates the outgoing and incoming signals and sends them on different wavelengths of light.

This is in contrast to traditional fiber optic technology, where separate strands of fiber optic cable are required for transmitting and receiving data. Bi-directional fiber optic technology can reduce the amount of fiber optic cabling required in a network and can also reduce the cost of installation and maintenance.

The QSFP-40G-BD-RX transceiver also uses advanced digital signal processing (DSP) technology to enhance the quality and reliability of the transmitted and received signals. The DSP technology compensates for distortions and attenuation that can occur during transmission over long distances, ensuring that the data is transmitted and received accurately and reliably.

Enhancing Network Efficiency

The QSFP-40G-BD-RX is a Cisco 40Gbps BI-Directional QSFP transceiver that can enhance network efficiency by improving data transfer rates and reducing latency. This transceiver uses a single-mode fiber optic cable to transmit data over distances of up to 10km, which is ideal for high-speed data centers and network applications.

One of the key features of the QSFP-40G-BD-RX is its ability to support bidirectional transmission on a single fiber. This means that data can be transmitted and received simultaneously on a single strand of fiber, which reduces the number of fibers required for a network connection. This results in a more efficient use of fiber optic cables, which can save on costs and reduce the complexity of network installations.

The QSFP-40G-BD-RX also supports a data transfer rate of up to 40Gbps, which is much faster than traditional Ethernet connections. This allows for faster data transfer and reduces latency, which can improve overall network performance. The transceiver also uses advanced signal processing and equalization technology to improve signal quality and reduce the risk of errors or signal degradation.

A High-Performance Transceiver

The QSFP-40G-BD-RX is a high-performance transceiver module designed for use in data center and networking applications. It is a Cisco 40Gbps bi-directional QSFP transceiver, which means it can transmit and receive data at a rate of 40 gigabits per second (Gbps) using a single fiber optic cable.

The "BD" in the module's name stands for "bi-directional," indicating that it can transmit and receive data on the same fiber using different wavelengths. This allows for the use of a single fiber optic cable instead of the two cables typically required for bi-directional communication.

The "RX" in the module's name refers to the module's ability to receive data. The QSFP-40G-BD-RX is designed to receive data using a wavelength of 1270 nanometers (nm) and transmit data using a wavelength of 1330 nm.

The QSFP-40G-BD-RX is compliant with the QSFP MSA (multi-source agreement) and is compatible with a wide range of networking equipment, including Cisco switches and routers. It supports a link length of up to 10 kilometers (km) over single-mode fiber optic cable and up to 100 meters (m) over multimode fiber optic cable.

In terms of performance, the QSFP-40G-BD-RX provides high-speed data transmission with low latency and low power consumption. It also includes advanced features such as digital diagnostic monitoring, which allows for real-time monitoring of the module's operating conditions, including temperature, voltage, and power consumption.
