This standard uses parallel optics, with four individual fiber strands transmitting data simultaneously to achieve the high data rate.
Data Rate
The 40GBASE-SR4 specification refers to a 40 Gigabit Ethernet standard that uses multimode fiber optics to transmit data at a rate of 40 Gbps. This standard is commonly used in data centers and high-performance computing environments to support high-speed networking requirements.
The 40GBASE-SR4 specification utilizes four parallel lanes of multimode fiber, each operating at a data rate of 10 Gbps. This allows for a total aggregated data rate of 40 Gbps. The maximum reach of 40GBASE-SR4 over OM3 multimode fiber is typically around 100 meters, while over OM4 multimode fiber, it can reach up to 150 meters.
It is important to note that as technology continues to advance, there may be updates or improvements to the 40GBASE-SR4 specification. For example, there may be developments in transceiver technology that allow for longer reach or higher data rates. It is always recommended to refer to the latest industry standards and specifications for the most up-to-date information on 40GBASE-SR4 and other networking technologies.
Fiber Type
The 40GBASE-SR4 specification refers to a standard for 40 Gigabit Ethernet over multimode fiber optics. The Fiber Type specified for 40GBASE-SR4 is OM3 or OM4 multimode fiber, which are designed to support high-speed data transmission over short distances.
OM3 fiber has a core size of 50 microns and is capable of supporting data rates up to 10 Gigabits per second over a distance of up to 300 meters. OM4 fiber, on the other hand, has a similar core size but offers improved performance, allowing for data rates of 10 Gigabits per second over a distance of up to 550 meters.
It is important to note that with the advancement of technology, there have been developments in fiber optics that offer even higher performance than OM3 and OM4. For example, OM5 fiber has been introduced to support higher data rates and longer distances, making it a suitable option for future-proofing network infrastructure.
In summary, the 40GBASE-SR4 specification typically utilizes OM3 or OM4 multimode fiber for high-speed data transmission over short distances, but newer fiber types like OM5 may offer enhanced performance for more demanding network requirements.
Maximum Reach
40GBASE-SR4 is a standard for Ethernet connections that use multimode fiber optic cables. The specifications for 40GBASE-SR4 include a maximum reach of 100 meters over OM3 fiber and 150 meters over OM4 fiber. This means that data can be transmitted at a speed of 40 gigabits per second over these distances using this standard.
In terms of the latest point of view, it is important to note that as technology continues to advance, there may be improvements in the reach and performance of 40GBASE-SR4.
