Your Path from 800G to 1.6T

Starting in 2024, the demand for 800G is increasing, and soon in 2025 and 2026 1.6T will also delivered to the market. We shall explain the form factors of 800G and 1.6T modules.

Based on the applications, there are Pluggable optical transceivers, Active optical cables, Active electrical cables, Active copper cables, and Direct-attached copper cables.
QSFP-DD800 Quad small-form-factor pluggable double density, it supports 32 ports in 1 RU, the max lane speed is 112Gb/s at 56GBd PAM4
OSFP-DD Octal small-form-factor pluggable double density, it supports 32 ports in 1 RU, the max lane speed is 112Gb/s at 56GBd PAM4
OSFP-XD Gen 1 Octal small-form-factor pluggable extra density, it supports 32 ports in 1 RU, the max lane speed is 224Gb/s at 112GBd PAM4

There are On-board optics also, the form factor is COBO（Consortium for On-Board Optics） its max lane speed is 56 Gb/s at 28 GBd PAM4

Overview of optics options for 800GbE
The growing demand for bandwidth in the Cloud, Artificial Intelligence, Machine Learning, etc, and future hyper-scale data centers drive the demand for 800GE Optics. Market researchers consider that 400G will hold sway until 2023 and that 800G will come into its own as of 2025. This article is introducing the…
Optical Interfaces of QSFP112 Optical Modules
The recommended location and numbering of the optical ports for 3 Media Dependent Interfaces (MDI) are shown as follows. The transmit and receive optical lanes shall occupy the positions depicted in the following when looking into the MDI receptacle with the connector keyway feature on top. QSFP112 optical MDI examples…
FAQ about QSFP-DD800
Q: HOW IS QSFP-DD800 DIFFERENT THAN QSFP-DD? A: The QSFP-DD800 MSA is focused on the next generation of the QSFP family of modules. It will focus on increasing the aggregate module bandwidth and increasing individual line speeds to 112 Gb/s. In addition, changes are anticipated to the specification in the…
