A cost optimized solution for up to 2km. Customers can use it for 400G to 400G connectivity as well as breakout 400G to 4x100G connectivity. Breakout option is often used for Leaf to ToR, in conjunction with 100G FR1 (100G FR1 is a new QSFP28 optics module used to plug into legacy 100G switches with NRZ electrical signals).


EN-QDD-LR4 Connectivity

The 400G-DR4 / XDR4 / PLR4 modules use a single row, angled (APC) MPO12 connector for use with parallel single mode fiber. Although a MPO12 cable can have up to 12 SMF fibers, only 8 out of the 12 fibers are used (4 for Tx and 4 for Rx). This is the same connector that is used on existing 100G and 40G QSFPs that use parallel SMF (e.g. 100G-PSM4, 40GPLR4 etc). An image, and drawing of an MPO12 connector are shown below.



Cabling required

EN-MTP8F-SM-FF-xxM is singlemode patch cable required for direct connectivity between QDD-XDR4.





EN-MTP4LCxxSM is a Singlemode MTP to 4 Duplex LC breakout cable is required to connect to 4 x QSFP-100G-FRs (EN-QSFP28-FR1) to a single OSFP-400G-DR4 (or EN-QDD-XDR4).
