With the rapid promotion and application of emerging technologies such as cloud computing, big data, the Internet of Things, artificial intelligence, and 5G, the continuous influx of data traffic has prompted major service providers to constantly re-examine the upgrade of data transmission speeds in data centers. Data center transmission equipment needs to increase the data transmission speed from the original 10Gbps, 25Gbps to 40Gbps, 100Gbps or even 400Gbps.
Since higher-speed optical Internet will inevitably bring challenges in terms of cost, power consumption, size, etc., the system architect of the data center must consider carefully to ensure the best combination choice, especially to reduce the failure rate and reduce power consumption. performance, improve compatibility, etc., so as to give full play to the performance improvements brought by hardware upgrades.
data center network
Here is an example of an upgrade from 10Gbps/25Gbps to 40G/100Gps:
Solution 1: 40G/100G QSFP to 10G/25G 4SFP+ passive copper core high-speed breakout cable:
40G/100G QSFP to 10G/25G 4SFP+ passive copper core high-speed branch cable is connected to one end of the 40G/100G QSFP port of a switch, and the other end is connected to 4 10G/25G SFP+ ports of a switch, which is a short-distance 10G /25G to 40G/100G transmission cost-effective method.
Solution 2: 40/100G QSFP to 10G/25G 4SFP+ active breakout cable:
40G/100G QSFP to 10G/25G 4SFP+ high-speed active optical cable, one end of this optical cable is 40G/100G QSFP interface, and the other end is 4 10G/25G SFP+ interfaces, which can complete 40G/100G equipment and 10G/ 25G device interconnection.
The cost of 40G QSFP+ active optical cable is lower than that of 40G QSFP+ optical module, and it has excellent performance of low insertion and low return loss. At the same time, the repeatability and interchangeability of 40G active optical cable is better than that of 40G QSFP+ optical module.
Solution 3: MPO Fiber Patch Cords:
Use two 12-core MPO trunk optical cables for transmission, one end is connected to a module box containing two 12-core MPO-LC jumpers, and then connected to 12 10G/25G (SFP+) optical modules through LC duplex jumpers; the other One end is connected to a 2-to-3 MPO conversion jumper, and the 2x12-core fiber channel is converted into a 3x8-core fiber channel, and then connected to three 40G/100G (QSFP) optical modules to easily complete 10G/25G and 40G/100G equipment interconnection between.
While this requires an additional patch panel within the data center, they are completely passive: they require no power, no cooling, and no UPS backup, reducing data center power consumption and cost overall. It has been proven to be the ideal solution for 40G/100G Ethernet.
