800G FR8 (2 km) Optical Interconnect Solution for Data Centers
Overview
GIGALIGHT’s 800G FR8 optical module adopts 8-channel LWDM wavelength-division multiplexing technology to enable 800GE transmission over dual fibers up to 2 km. Compared with 800G 2×FR4 solutions, it saves two fiber cores, significantly reducing deployment and O&M costs.
Designed for future Optical Circuit Switch (OSC) architectures, the 800G FR8 supports single-fiber single-mode BiDi 800GE transmission up to 500 m via integrated or external optical circulators, effectively conserving OSC port resources and delivering greater network efficiency and value.
Technical Highlights
- 8x100G PAM4 modulation to realize 800Gbps high speed transmission
- Support both OSFP and QSFP-DD standard
- Built-in MUX/DEMUX, only dual LC fiber for bidirectional
- Transmission distance up to 2km
- By adopting an advanced power optimization solution, power consumption < 16
- OMA sensitivity less than -4.5 dBm
