Overview
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.
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
