Fibrecross Unveils Next-Generation 800G Optical Transceiver

ALHAMBRA, Calif. - June 19, 2025 - PRLog -- What Is an 800G Optical Transceiver?

An 800G optical transceiver is a pluggable module designed to transmit and receive data at an aggregate rate of 800 gigabits per second. Unlike earlier generations that used lower‑speed lanes, modern 800G modules often employ advanced modulation formats (for example, PAM4 or dual‑polarization quadrature amplitude modulation, DP‑QAM) and high‑speed electrical interfaces (such as 8×112 Gbps or 4×200 Gbps) to pack more data into each wavelength channel.

Technical Advantages

1. Higher Spectral Efficiency
   By leveraging PAM4 or DP‑QAM, 800G transceivers double the bits-per-symbol compared to traditional non‑return‑to‑zero (NRZ) formats. This results in greater throughput per wavelength and helps extend the useful life of existing fiber infrastructure.
2. Lower Power per Gigabit
   Integrated photonic technologies and optimized DSP algorithms reduce power consumption to as low as 10 pJ/bit, making 800G modules more energy‑efficient than multiple parallel lower‑speed links.
3. Scalability & Form Factor Flexibility
   The emergence of compact form factors—such as QSFP-DD800 (4 × 200 Gbps) and OSFP (8 × 112 Gbps)—ensures that modern switches and routers can scale port density without compromising on cooling or board space.
4. Extended Reach Options
   Many 800G transceivers support both short‑reach (SR) for data‑center interconnects and long‑reach (LR) variants for metro or regional networks, covering distances from a few meters up to 120 km on single‑mode fiber.
