More Details of 1 Ports Transceiver Module

The Cisco QSFP-100G-SR4-S is a multi-mode transceiver module designed for use in 100 Gigabit Ethernet (100 GbE) networks. It is compliant with the IEEE 802.3bm standard for 100GBase-SR4 and uses four parallel optical channels to transmit data at a rate of 25 Gbps per channel.

The module is designed for use in short-reach multi-mode fiber (MMF) environments, with a maximum distance of 100 meters over OM3 or 150 meters over OM4 fiber. It uses a wavelength of 850nm and is compatible with the QSFP form factor, which is commonly used in data center and enterprise networks.

The Cisco QSFP-100G-SR4-S module includes advanced features such as digital optical monitoring (DOM) for real-time monitoring of optical signal power and temperature. It also includes a diagnostic monitoring interface (DMI) that allows for easy troubleshooting and monitoring of the module's performance.

The module is designed for use with Cisco's M6 and M12 series switches, as well as other Cisco 100 GbE platforms that support QSFP transceivers. It is also compliant with the MSA (Multi-Source Agreement) standard for 100 GbE transceivers, which means it is compatible with other vendor's equipment that also comply with the MSA standard.

Compliant Standards of 100GBPS Transceiver

The Cisco QSFP-100G-SR4-S transceiver module is compliant with the following standards:

  • IEEE 802.3bm 100GBase-SR4: This standard defines the specifications for 100 Gigabit Ethernet over multi-mode fiber (MMF) using a wavelength of 850nm.
  • SFF-8436: This standard defines the form factor and mechanical specifications for the QSFP transceiver module.
  • SFF-8472: This standard defines the electrical and optical specifications for the QSFP transceiver module.
  • RoHS (Restriction of Hazardous Substances): This standard ensures that the transceiver module is free from hazardous materials and is safe for the environment.
  • MSA (Multi-Source Agreement): This agreement ensures that the transceiver module is compatible with other equipment from different vendors.
  • IEC (International Electrotechnical Commission) 61300-3-35: This standard defines the environmental and mechanical testing requirements for optical transceiver modules.
  • TIA (Telecommunications Industry Association) 942: This standard defines the requirements for data center infrastructure including the transceiver module.

Resiliency and High Availability

Resiliency refers to the ability of a system or device to continue functioning in the event of a failure or disruption. The Cisco QSFP-100G-SR4-S 100GBase-SR4 Multi-Mode Transceiver Module is designed with resiliency in mind, meaning that it is able to withstand and recover from potential failures or disruptions in the network.

High availability refers to the ability of a system or device to remain operational and accessible at all times. The Cisco QSFP-100G-SR4-S 100GBase-SR4 Multi-Mode Transceiver Module is designed with high availability in mind, meaning that it is able to maintain a consistent level of performance and availability even in the event of disruptions or failures.

The Cisco QSFP-100G-SR4-S 100GBase-SR4 Multi-Mode Transceiver Module uses advanced technologies such as wavelength-division multiplexing (WDM) and multi-mode fiber (MMF) to ensure high availability and resiliency in the network. These technologies allow the module to transmit data over multiple wavelengths and fibers, providing redundant paths for data transmission and increasing the overall reliability and availability of the network. Additionally, the module is built with advanced error detection and correction mechanisms to detect and recover from errors in the network, further increasing its resiliency and high availability.
