What type of connector is a cisco qsfp 40g sr4?
The Cisco QSFP-40G-SR4 is a type of connector commonly used in networking equipment. It is a Quad Small Form-factor Pluggable (QSFP) transceiver module that supports a data transfer rate of 40 gigabits per second (Gbps). The "SR4" in the name refers to its functionality as a short-range transceiver, capable of transmitting data over a distance of up to 100 meters using multi-mode fiber optic cables. This type of connector is widely used in data centers and high-speed network environments for connecting switches, routers, and other networking devices.
QSFP (Quad Small Form-factor Pluggable)
The Cisco QSFP-40G-SR4 is a type of QSFP (Quad Small Form-factor Pluggable) connector. QSFP connectors are widely used in data centers and high-speed networking applications to provide high-density and high-bandwidth connectivity.
The QSFP-40G-SR4 connector is specifically designed for 40 Gigabit Ethernet (GbE) applications. It supports a maximum data transfer rate of 40 Gbps over multi-mode fiber optic cables. The "SR4" in the product name stands for "Short Reach 4," indicating that it is designed for short-range transmissions.
The QSFP-40G-SR4 connector utilizes four parallel fiber optic lanes, with each lane transmitting data at a rate of 10 Gbps. This allows for a total aggregated data transfer rate of 40 Gbps. The connector uses an MPO (Multi-fiber Push-On) interface, which enables easy and quick connections between the QSFP module and the fiber optic cables.
It is important to note that technology is constantly evolving, and there may be newer and more advanced connectors available in the market. However, as of the latest information available, the Cisco QSFP-40G-SR4 connector remains a widely used and reliable option for 40 GbE applications, particularly in data center environments.
In conclusion, the Cisco QSFP-40G-SR4 is a QSFP connector specifically designed for 40 GbE applications. It utilizes an MPO interface and supports a maximum data transfer rate of 40 Gbps over multi-mode fiber optic cables.
40G (40 Gigabit per second)
The Cisco QSFP-40G-SR4 is a 40 Gigabit per second (40G) transceiver module designed for high-speed data transmission in data centers and enterprise networks. It uses a Quad Small Form-factor Pluggable (QSFP) connector, which is a compact, hot-pluggable transceiver interface widely used for high-density applications.
The QSFP-40G-SR4 module supports parallel multimode fiber (MMF) connections, providing four independent transmit and receive channels, each operating at 10G. It uses a 12-fiber MPO/MTP connector, which allows for easy and efficient connectivity in high-density environments. The MPO/MTP connector is a standardized interface that simplifies the cabling process and enables quick deployment of network connections.
The QSFP-40G-SR4 module is designed to support short-range transmission distances of up to 100 meters over OM3 MMF and up to 150 meters over OM4 MMF. It utilizes vertical cavity surface emitting laser (VCSEL) technology to achieve high-speed data transmission with low power consumption.
As technology advances, the demand for higher data rates and increased bandwidth continues to grow. While 40G is still widely used in many networks, there is a shift towards higher-speed interfaces such as 100G and 400G. However, the QSFP-40G-SR4 remains a reliable and cost-effective solution for 40G connectivity in existing infrastructure.
In conclusion, the Cisco QSFP-40G-SR4 module utilizes a QSFP connector and supports 40G data transmission over parallel multimode fiber. It is a widely adopted solution for high-speed networking and is compatible with various Cisco networking equipment.
Cisco (Cisco-specific implementation)
The Cisco QSFP-40G-SR4 is a specific implementation of the QSFP (Quad Small Form-factor Pluggable) form factor connector. The QSFP connector is a hot-pluggable transceiver that is commonly used for high-speed data communication applications.
The QSFP-40G-SR4 is designed specifically for 40 Gigabit Ethernet (GbE) applications. It supports short-range multi-mode fiber connections and operates over four lanes of parallel fiber, with each lane carrying a 10 GbE signal. This enables a total data transfer rate of 40 Gbps.
The connector itself is a compact, low-profile module that is easily inserted and removed from the network device. It features a 12-fiber MPO (Multi-fiber Push-On) connector interface, which is commonly used for multi-mode fiber connections. The MPO connector allows for easy and efficient fiber cabling, as it can accommodate multiple fibers in a single connector.
It's important to note that the Cisco QSFP-40G-SR4 is a Cisco-specific implementation of the QSFP connector. While the QSFP connector is an industry-standard form factor, Cisco may have implemented additional features or functionality specific to their networking equipment. Therefore, it is always recommended to check the compatibility and specifications provided by Cisco for their specific implementation of the QSFP-40G-SR4 connector.
As technology advances, it's worth noting that newer and faster connectors, such as the QSFP-100G-SR4, have been introduced to support higher data transfer rates. However, as of the latest information available, the QSFP-40G-SR4 remains a widely used connector for 40 GbE applications.
