Description
Configure the optical module parameters of QSFP (Quad Small Form-Factor Pluggable) modules for all the media lanes. The following QSFP modules are supported:
-
QSFP+ : 4 host lanes, supports 10g per lane, total bandwidth of 40g
-
QSFP28 : 4 host lanes, supports 25g per lane, total bandwidth of 100g
-
QSFP56 : 4 host lanes, supports 50g per lane, total bandwidth of 200g
-
QSFP28-DD : 8 host lanes, supports 25g per lane, total bandwidth of 200g
-
QSFP56-DD : 8 host lanes, supports 50g per lane, total bandwidth of 400g
The following specifications standardize how the host device interacts with the QSFP optical modules:
-
The 4-lane QSFP modules adhere to SFF-8636 management interface specification.
-
The 8-lane QSFP-DD modules adhere to CMIS (Common Management Interface Specification).
You can configure optical module parameters for QSFP28 and QSFP28-DD optical modules for Juniper qualified optics as well as third-party optics from Junos OS. You cannot configure optical module parameters for QSFP copper DAC (direct attach cables) or QSFP load modules.
