Recently, GIGALIGHT has introduced the 100G QSFP28 SR1 and 200G QSFP56 SR2 optical transceivers, specifically designed for short-distance interconnections. Leveraging cutting-edge technology, these transceivers empower customers to effortlessly construct future-ready, efficient network architectures.

Why Opt for 100G QSFP28 SR1 and 200G QSFP56 SR2?

Faced with the widely adopted 100G QSFP28 SR4 and 200G QSFP56 SR4 optical transceivers in the market, customers may wonder: Why choose these new offerings from GIGALIGHT? The answer lies in their tailored design to meet the demands of future network upgrades.

While traditional optical transceivers are mature and cost-effective, they struggle to keep pace with the requirements of high-speed network architectures like 400G/800G amidst the AI-driven network upgrade wave.

Technological Innovation to Meet Future Challenges

With the advent of 100G PAM4 technology, most 400G/800G optical transceivers now employ this technology (4×100G PAM4 and 8×100G PAM4). In this context, continuing to use 4-channel 25G NRZ (100G QSFP28 SR4) or 4×50G PAM4 (200G QSFP56 SR4) technologies would lead to issues such as speed mismatch, port wastage, and soaring costs. GIGALIGHT’s 100G QSFP28 SR1 and 200G QSFP56 SR2 optical transceivers are precisely engineered to address these pain points.

Case Study: Seamless Integration and Effortless Upgrades

Consider the example of connecting an NVIDIA ConnectX-7 (dual-port 200Gb/s) network card with a 400G QSFP112 switch. Direct connection would result in link downtime, with the switch reporting an “Unsupported speed” error. However, introducing the 200G QSFP56 SR2 optical transceiver resolves the issue. By utilizing dual-channel PAM4 modulation technology, this transceiver intelligently splits the 400G QSFP112 port into two independent 200G channels, enabling perfect interconnection with the 200G QSFP56 network card without hardware modifications. Similarly, a 400G QSFP112 switch can automatically recognize a 4×100G link through four 100G QSFP28 SR1 optical transceivers.

When connecting to an 800G switch, direct interconnection can be achieved using 8×100G QSFP28 SR1 or 4×200G QSFP56 SR4 transceivers. Moreover, GIGALIGHT’s 100G QSFP28 SR1 and 200G QSFP56 SR2 transceivers can also directly interconnect with each other, offering great convenience.
