Description

The Arista OSFP-400G-DR4 is a 400GBASE-DR4 OSFP optical transceiver designed for high-density data centre deployments requiring 400GbE connectivity over parallel single-mode fibre. Utilising PAM4 modulation across four 1310nm lanes, it delivers 400Gb/s at distances up to 500m over OS2 SMF via an MPO-12 APC connector — ideal for spine-leaf fabric interconnects and high-performance compute clusters. It supports breakout to 4x 100GBASE-DR, enabling flexible integration with existing 100G QSFP infrastructure.

Compliant with OSFP MSA, IEEE 802.3ck, and CMIS standards, the OSFP-400G-DR4 is compatible with Arista 400G platforms including the 7050X4, 7060X4, 7060X5, 7358X4, and 7368X4 series. Digital Optical Monitoring (DOM) provides real-time diagnostics for proactive network management. Need it fast? iptrading.com.au delivers across Australia — shop now.

FAQs

Q: What fibre type and connector does the OSFP-400G-DR4 require?
A: The OSFP-400G-DR4 uses an MPO-12 APC connector and requires parallel single-mode fibre (SMF/OS2). It supports reaches up to 500m, making it well suited for within-campus or inter-rack data centre runs.

Q: Does the OSFP-400G-DR4 support breakout to 100G connections?
A: Yes. The module supports breakout to 4x 100GBASE-DR, allowing interoperability with standard 100G-DR QSFP28 transceivers. This makes it easy to integrate into mixed 100G/400G network architectures.

Q: Which Arista switch platforms are compatible with this transceiver?
A: The OSFP-400G-DR4 is compatible with Arista 400G OSFP-capable platforms including the 7050X4, 7060X4, 7060X5, 7358X4, and 7368X4 series. Confirm port compatibility with your specific chassis configuration before ordering.

Q: Can this transceiver be used with older 40G or 100G QSFP equipment?
A: With the optional ADPT-O-Q-100G mechanical adapter, the OSFP-400G-DR4 can be used in QSFP (40G/100G) ports, providing a degree of backward compatibility for phased 400G migrations.

Q: Does the module support Digital Optical Monitoring (DOM)?
A: Yes, the OSFP-400G-DR4 supports Digital Optical Monitoring (DOM/DDM), allowing real-time visibility into optical power levels, temperature, voltage, and bias current for proactive fault detection and diagnostics.

Q: Can I purchase the Arista OSFP-400G-DR4 in Australia through IP Trading?
A: Yes. IP Trading is an Australian B2B IT hardware reseller stocking Arista optics including the OSFP-400G-DR4. We deliver nationwide — visit iptrading.com.au to order or contact us for volume pricing and availability.
