Arista ADPT-O-Q-100G3 | OSFP to 100G QSFP Passive Port Adapter

Q: What does the Arista ADPT-O-Q-100G3 adapter do?
A: It is a passive mechanical adapter that allows 100G QSFP optical modules to be installed into an OSFP host port. The OSFP port must be configured for 100G operation. No active components or software configuration are required.

Q: Which QSFP modules are compatible with the ADPT-O-Q-100G3?
A: The adapter supports 100G QSFP optical modules only — including SR4, LR4, CWDM4, and ZR4 variants on supported Arista platforms. It does not support copper cables, 200G QSFP optical modules, or QSFP-DD modules.

Q: Does the adapter require any configuration or drivers?
A: No. The ADPT-O-Q-100G3 is a completely passive mechanical adapter. It requires no active components, no drivers, and no software configuration. Simply insert the compatible 100G QSFP module and plug the assembly into the OSFP port.

Q: Are there any precautions when using this adapter on short-reach fibre links?
A: Yes. Optical attenuation may be required for shorter links to prevent the receiver from being damaged by excessive optical power. Always consult the Arista Transceiver and Cable Guide for link budget and platform-specific recommendations.

Q: Which Arista platforms support the ADPT-O-Q-100G3 adapter?
A: Supported platforms are listed in the Arista Transceiver and Cable Guide. Generally, any Arista platform with OSFP ports that can be configured for 100G operation is a candidate. Confirm compatibility via the guide or contact IP Trading for platform-specific advice.
