In the vast constellation of optical communications, every flicker of light beats as the pulse of the information age. As industry giants wager on the future of 4-channel optical transceivers, GIGALIGHT, a brand that wings on innovation and steers with differentiation, is quietly rewriting the rules of transmission. We understand that if we cannot lead the trend, we will create our own path—the 8-channel optical transceiver is the dazzling fruit of this belief.

8-Channel Optics: GIGALIGHT’s Persistence and Innovation

Since its inception, GIGALIGHT has deeply understood that true innovation stems from profound insight and relentless pursuit of technology. In the field of optical transceivers, we stand out, adhering to the development philosophy of 8-channel optics and crafting a series of high-performance, high-reliability 8-channel optical transceiver product lines. Recently, the 800G QSFP-DD FR8/LR8, designed to fill the gap for medium to long transmission distances, is about to be launched.

GIGALIGHT 800G QSFP-DD FR8/LR8

The newly launched 800G FR8/LR8 adopts the QSFP-DD package and an EML emitter. The 800G QSFP-DD FR8 uses CWDM wavelengths for a transmission distance of 2km, while the 800G QSFP-DD LR8 employs LAN-WDM wavelengths for a transmission distance of 10km.

Compared to 800G FR4/LR4, GIGALIGHT’s 800G series optical transceivers boast superior OSNR performance due to the better signal-to-noise ratio of 100G PAM4 compared to 200G PAM4. This means that in the vast stream of information, our optical signals can travel farther and more stably.

The 800G QSFP-DD FR8/LR8 optical transceivers are suitable for core transmission scenarios in high-performance, high-speed data centers and telecommunication networks:

Data Center Interconnect

Meeting high-speed data transmission needs (supporting multi-wavelength and high channel bandwidth).

• LR8 (LWDM8) supports long-distance transmission of 10km, ideal for connections between large-scale data centers.
• FR8 (CWDM8 with 10nm spacing) supports 2km, suitable for short-distance interconnects between data centers.

Telecom Carrier Networks

Applied in metropolitan area networks and core networks for long-distance optical fiber communication.

Cloud Computing and AI Networks

Satisfying the requirements of cloud services, AI workloads, and other scenarios for large bandwidth, low latency, and high energy efficiency.

High-Frequency Trading and Other Fields

Supporting communication needs for rapid response and low latency.

The Path of Differentiation: GIGALIGHT’s Independent Thinking

GIGALIGHT’s 800G QSFP-DD FR8/LR8 will soon be available, and we are also developing OSFP packaging—stay tuned. We believe that true differentiation does not lie in blindly following trends, but in deeply understanding and anticipating the future. GIGALIGHT, as a pioneer, is leading the new era of 8-channel optical transmission.
