The Popular 100G High-speed Optical Transceivers of Data Center in 2018

Since 2018, 100G high-speed optical transceivers have been deployed in large-scale data centers. The 100G QSFP28 series products are favored in large data center network architectures such as Microsoft, Google, and Facebook.

The 100G QSFP28 PSM4, 100G QSFP28 CWDM4, 100G QSFP28 LR4 optical transceiver is widely used in the construction of data center networks. It has won a large market share compared to other 100G optical transceivers. It can be said that it is a popular product in 100G high-speed optical transceivers. In general, if a product can be recognized by the market and widely used, the technical advantage must be the important reason.

Gigalight 100G PSM4, 100G CWDM4, 100G LR4 are using for data center. These products use technologies such as COB, WDM, mini TO and so on, which greatly reduced the cost, can save money for high-volume optical transceivers in the data center.

Automated Production and Chip-On-Board(COB) Packaging Technology

The chip-on-board package technology is an illuminant in which multiple of LED chips are integrally packaged on the same substrate.

Gigalight 100G QSFP28 PSM4, 100G QSFP28 CWDM4, 100G QSFP28 LR4 optical transceivers use automated production line and COB technology, greatly reducing cost and product power consumption.

WDM technology

In addition to COB technology, Gigalight 100G QSFP28 CWDM4 and 100G QSFP28 LR4 optical transceivers all introduce WDM technology. In optical transmission networks, WDM technology is considered to be an effective means to expand the transmission capacity of existing optical networks. It can increase the optical signal transmission capacity of existing optical fibers in the most cost-effective way, thus quickly meeting the increasing high bandwidth requirements of people. The most direct impact on life is that we go online, watch TV, make calls faster and more smoothly.

Wavelength Division Multiplexing (WDM) is a Multiplexer (Mux) that multiplexes optical carrier signals of different WDM wavelengths onto a single fiber for transmission at the transmitting end, and then uses a Demultiplexer(Demux) at the receiving end to transmit each the WDM wavelength separation technology, each WDM wavelength signal is independent of each other and is not affected by any transmission protocol and rate.

In addition, WDM technology enables bidirectional transmission of optical signals over a single fiber. This technology virtualizes one fiber into multiple fibers, which not only simplifies the structure of the optical transmission network, but also greatly saves fiber resources, thereby reducing the deployment cost of the optical network.

Using Mini TO Technology

Gigalight uses homemade Mini TO to effectively reduce costs and improve product reliability.

Conclusion

Through long-term technical accumulation, Gigalight self-developing optical devices, homemade TOSA/ROSA, gradually formed its own transmitting and receiving device packaging technology platform. The transmitter adopts the self-made mini TO plus AWG chip, and the receiving end adopts the COB packaging process, which greatly optimizes the product cost. In 2019, 100G optical transceivers will still occupy a mainstream position in data center deployment. In the new year, Gigalight will continue to optimize its production technology and will provide more high-quality 100G high-speed optical interconnect products for data centers.

Gigalight 100G Optical Modules Passed the Connectivity Test of Multiple Cloud Service Providers

Shenzhen, China, May 19, 2018 – Gigalight announced the 100G series optical transceiver modules have passed the connectivity test of multiple cloud service providers. The Gigalight 100G series products include 100G QSFP28 SR4 multi-mode VCSEL optical modules and 100G QSFP28 CWDM4 single-mode WDM optical modules. The interconnection test covers the mainstream cloud devices of major brand equipment vendors and the optical transceiver module products of our partners.

Qualified 100G Series Optical Transceiver Modules

Gigalight has always been among the top 10 companies in the world of optical interconnects with its invention of active optical cables and deep innovation. However, Gigalight is essentially an integrated solution provider of optical transceiver modules and optical network devices. Gigalight ships a large number of 10G multimode and 10G single-mode optical modules and 40G multimode SR4 optical modules to the world. In the field of 40G single-mode optical modules, Gigalight’s main customers include global TIE1 equipment vendors. The cloud service providers have directly verified Gigalight’s 100G optical modules since the end of 2017. The successful interconnection results so far have greatly encouraged Gigalight’s confidence in deploying 100G optical modules in bulk in the cloud.

Global Data Center Infrastructure Ecosystem

Global Data Center Infrastructure Ecosystem

Gigalight has a deep optical interconnect product line. Among this product line, the multimode optical interconnect products based on the VCSEL technology applications are the traditional advantages of Gigalight, including the cost-effective and reliable 100G QSFP28 SR4 optical modules with good compatibility.
