Hardware Products Co., Ltd. follows the revolution of qsfp28 MSA optics: Data Center

The adoption rate of qsfp28 MSA compatible optics has continued to rise in the past few years. It is predicted that more than half of the data centers will turn to qsfp28 MSA compliant optics. Considering the explosive growth of data, the traditional 10g or even 40g may not be enough. Therefore, qsfp28 MSA will become a new standard. It has the following advantages.

Cost efficiency - qsfp28 MSA optics now provides a compelling price point, providing greater capacity growth. Moreover, it still proves the future of the network with unparalleled bandwidth. The growth of qsfp28 MSA fiber deployment will undoubtedly reduce the cost of 100g fiber.丨Speed and capacity - SFP + and qsfp + optics are not enough for data intensive industries. Therefore, qsfp28 MSA optical is specially designed to transmit large amounts of data with ultra-low delay.丨Flexibility - 100g will be the preferred technology across long-distance networks. The 100g network can be customized, optimized and easily expanded to adapt to future changes.丨Qsfp28 enclosure with qsfp28 MSA compatible optics overview

Qsfp28 MSA fiber usually has the same floor area and panel density as 40g qsfp +. But it is implemented with four 25 Gbps channels. By upgrading the electrical interface, qsfp28 MSA optical can support signals up to 28gbps. Although the qsfp28 transceiver retains all the physical dimensions of its predecessor, its powerful ability to increase density, reduce power consumption and reduce the price per bit exceeds them. Here are some qsfp28 MSA compatible optics for different applications.丨Qsfp28 housing is applied to 100g Sr4 qsfp28丨The 100g Sr4 qsfp28 is designed to support short-range transmission through multimode fiber. The transceiver module can support 100g transmission up to 70m on OM3 MMF and 100m transmission on OM4 MMF. Through MTP interface, 100g Sr4 qsfp28 MSA complaint module can be realized through 8 optical fibers × 25g bidirectional transmission.

丨Qsfp28 precision die casting shell applied to 100g qsfp28 LR4丨The 100g qsfp28 LR4 is a qsfp28 MSA complaint and is specially designed for long-distance transmission. Qsfp28 LR4 adopts WDM technology for 4 × The four 25g optical signals are transmitted at four different wavelengths. The 100g LR4 qsfp28 module has a duplex LC interface and can realize 100g bidirectional transmission up to 10km through single-mode optical fiber.丨Qsfp28 structure is applied to qsfp28 100g psm4丨The 100g psm4 is standardized by qsfp28 MSA. It uses four parallel optical fibers (channels) running in each direction, and each channel carries 25g optical transmission. The 100g psm4 module sends signals down to eight optical fiber cables through the MTP interface. The working distance of 100g psm4 is limited to 500m.丨Qsfp28 housing is applied to qsfp28 100g dwdm4丨The 100g dwdm4 uses WDM technology - an optical multiplexer and demultiplexer to reduce the number of optical fibers to 2. Because it is compatible with qsfp28 MSA, 100g dwdm4 can work on 2 km long single-mode fiber through duplex LC interface. Compared with qsfp28 LR4, it has shorter transmission distance and lower cost.丨Qsfp28 housing is applied to qsfp28 MSA compatible cable

In addition to all qsfp28 MSA 100g transceivers mentioned above, high-speed cables are also deployed in the 100g network. The cable can be qsfp28 to 4 SFP 28 copper cable (DAC) or active optical cable (AOC). Qsfp28 to 4 sfp28 DACs provide the lowest cost, up to 3 meters. They are usually used in the racks of data centers or as chassis to chassis interconnects in large switches and routers. Qsfp28 AOC is lighter and can provide a longer extension range, up to 100 meters.丨Qsfp28 housing application in conclusion

Qsfp28 MSA compliant 100g optical devices are indispensable components for applying 100g to infrastructure. They can also be easily extended to 100g networks, as simple as 10g. With higher port density, lower power consumption and lower cost, qsfp28 MSA transceiver is an ideal choice for large data centers and future network expansion. Therefore, we can not do without precision design, precision mold, precision casting and standard production. We can find Dongguan Shuwang Hardware Products Co., Ltd!"
