transceiver module QSFP-DD 400GE SR8 100 m OM4 & 70 m OM3

Function Descriptions
OM3680SX200 is a parallel 400GE Quad Small Form Factor Pluggable Double Density (QSFP-DD) SR8
optical module designed for optical communication applications. The optical module uses a 4-level pulse
amplitude modulation (PAM4) format. The optical module provides point-to-point 400 Gigabit Ethernet
links over eight pairs of multimode fiber, with a reach of up to 100 m for OM4 (MMF) and 70 m for OM3
(MMF).
It is compliant with QSFP-DD MSA standard and IEEE 802.3cm 400GBASE-SR8 standard and IEEE
802.3bs 400GAUI-8 standard. Digital diagnostics functions are available via the I2C interface, as
specified by the QSFP-DD MSA.

Pin Descriptions
The QSFP-DD SR8 module edge connector consists of a single paddle card with 38 pads on the top and
38 pads on the bottom for a total of 76 pads. The pads are defined in such a manner to accommodate
insertion of a QSFP module into a QSFP-DD receptacle.
