The 800G QSFP-DD SR8 is a high-performance, hot-pluggable optical transceiver designed for next-generation 800G Ethernet links in hyperscale data centers and AI computing clusters. Utilizing 8 channels of 100G PAM4 modulation and 850nm VCSEL technology, it provides reliable short-reach connectivity (up to 100m) over multimode fiber (MMF).

• Massive Bandwidth: Supports a total aggregate data rate of 800Gbps.

• Low Power Consumption: Optimized thermal design with power consumption < 14W.

• High Reliability: Built-in 7nm DSP and 850nm VCSEL/PIN array.

• Standard Compliance: Compliant with QSFP-DD MSA, IEEE 802.3db, and CMIS 5.0.

Q1: What is the maximum transmission distance of the 800G SR8 module?

A: It supports up to 60m over OM3 MMF and 100m over OM4/OM5 MMF, making it ideal for leaf-to-spine connections within the same data center hall.

Q2: Does this module support 2x400G breakout applications?

A: Yes, the 800G SR8 can be used in breakout mode to connect with two 400G SR4 modules using a specific MPO breakout cable, providing flexibility for network upgrades.

Q3: How does the module handle heat dissipation in high-density environments?

A: Our 800G QSFP-DD modules feature a specialized finned top shell design and low-power 7nm DSP chips to ensure stable performance even in fully loaded 800G switches.
