Signal Quality and Error Control
The QSFP-40G-SR-BD Cisco QSFP+ Multi Mode 40 Gigabits Transceiver Module is a high-performance transceiver designed for use in 40 Gigabit Ethernet (40GbE) applications over multi-mode fiber (MMF) cable. Here are some details about signal quality and error control in this transceiver module:
Signal Quality: The QSFP-40G-SR-BD transceiver uses a four-channel parallel design, where each channel transmits and receives signals over a separate fiber strand in the MMF cable. The module supports transmission distances of up to 150 meters over OM4 MMF and up to 100 meters over OM3 MMF.
To ensure high signal quality and low bit error rates, the transceiver uses advanced digital signal processing (DSP) technology. The DSP algorithms compensate for impairments caused by the MMF cable, such as modal dispersion and attenuation, to ensure that the received signal is clear and error-free. The transceiver also supports optical power monitoring, which allows the user to monitor the power levels of the transmitted and received signals in real-time and ensure that they are within the acceptable range.
Error Control: To prevent errors in the transmitted data, the QSFP-40G-SR-BD transceiver uses a variety of error control mechanisms, including:
- Forward Error Correction (FEC): FEC is a technique that adds redundancy to the transmitted data to detect and correct errors that may occur during transmission. The QSFP-40G-SR-BD transceiver supports the IEEE 802.3ba standard FEC, which uses a 544-bit codeword to protect each 512-bit block of data.
- Cyclic Redundancy Check (CRC): The transceiver also uses CRC, which is a simple error detection mechanism that calculates a checksum of the transmitted data and compares it with the received checksum to detect errors.
- Automatic Laser Shutdown (ALS): The QSFP-40G-SR-BD transceiver also features ALS, which automatically shuts down the laser transmitter in the event of a fault, such as excessive optical power or high temperature. This helps prevent damage to the transceiver and the connected equipment.
Reliability of 40GBPS Module
The Cisco QSFP-40G-SR-BD is a highly reliable transceiver module that is designed to provide consistent and reliable performance in a variety of networking environments. It is equipped with advanced features to help ensure the integrity of the data being transmitted, such as error correction and packet retransmission. The module is also designed to be hot-swappable, so it can be easily added or removed from the network without disrupting the operation of the network. Additionally, the QSFP-40G-SR-BD is tested to ensure that it meets a high level of quality and reliability, further contributing to its overall dependability. Overall, the QSFP-40G-SR-BD is a reliable and robust transceiver module that can be trusted to deliver consistent and reliable performance in a variety of networking applications.
Power Consumption of Multi Mode Transceiver Module
The QSFP-40G-SR-BD Cisco QSFP+ Multi-Mode Transceiver Module is a high-performance transceiver module designed for use in 40 Gigabit Ethernet links over multi-mode fiber. This transceiver module operates on a 40 Gigabit Ethernet link using a wavelength of 850 nm and supports transmission distances of up to 150 meters over OM4 multi-mode fiber.
The power consumption of the QSFP-40G-SR-BD transceiver module is typically around 1.5 watts. The actual power consumption may vary depending on the specific configuration of the network and the type of equipment being used.
It is important to note that power consumption can have a significant impact on the overall performance of a network, as excessive power consumption can lead to overheating and reduced system reliability. To ensure optimal performance and reliability, it is important to select a transceiver module that is designed to operate within the specific power requirements of your network infrastructure.
