September 23, 2025, Shenzhen, China. – The annual ECOC is set to open in Copenhagen, Denmark, where GIGALIGHT will showcase its latest 800G AI & Data Center interconnect solutions at Booth C1321.

Breaking Through 800G: Redefining Next-Generation Data Center Connectivity

Beyond the mainstream 800G DR8/2×FR4 and VR8 solutions, GIGALIGHT is introducing three “New Forces” to drive traditional 800G data centers toward the frontiers of diverse applications.

New Force #1: 800G QSFP-DD/OSFP FR8 (Single-Fiber WDM)

GIGALIGHT’s 800G FR8 leverages 8-lane LWDM multiplexing to deliver 800GE transmission over 2 km with duplex fibers. Compared to the 800G 2×FR4 design, it saves two fiber strands, significantly reducing deployment and O&M costs.

For next-generation optical circuit switch (OSC) systems, the FR8 can also support single-fiber single-mode BIDI 800GE up to 500 m via built-in or external circulators—maximizing OSC port efficiency and overall network value.

New Force #2: 800G OSFP XPSM8 / 8ER (SiPh + APD)

Built on a 1310 nm silicon photonics modulation platform with APD receivers, the 800G OSFP XPSM8/8ER modules feature dual MPO-12 interfaces and enhanced sensitivity margins—ideal for specialized data center architectures.

XPSM8: Up to 20 km reach
8ER: 30 km+ reach

This series extends the reach of 800G OSFP DR8++/PLR8 and is well-suited for networks with higher link loss, such as those incorporating optical backplane switches (OBS).

New Force 3: 800G OSFP DR8 LPO+ (Trusted Linear Drive Optics)

Unlike conventional LPO modules, GIGALIGHT’s trusted LPO+ silicon photonics modules ensure channel stability and consistency across all temperature conditions—a capability that traditional LPO silicon photonics modules currently lack. The 800G OSFP DR8 LPO+ adopts 1310 nm SiPh with MPO-12/APC interface, supports 500 m transmission, and operates below 8.5 W.

By eliminating the DSP, power consumption is reduced by up to 50% while latency drops dramatically—delivering a major advantage in AI/ML clusters and high-performance computing environments where ultra-low power and latency are critical.

Looking Ahead

In addition to these three groundbreaking 800G interconnect solutions, GIGALIGHT is preparing to launch a new wave of patented 800G AI & DC network architectures with even greater impact. The industry won’t have to wait long to witness these upcoming innovations.
