Description

The Arista OSFP-400G-XDR4-S is a 400Gbps OSFP optical transceiver module designed for high-density data centre deployments over parallel single-mode fibre. Operating as 4x 100GBASE-FR lanes at 1310nm with PAM4 modulation, it supports distances up to 2km and enables flexible breakout connectivity to 4x 100GBASE-FR ports — making it ideal for spine-leaf interconnects and high-bandwidth 400G switching fabrics. SN optical connectors deliver superior port density compared to traditional MPO-based solutions.

Built to OSFP MSA and IEEE 802.3bs standards, this transceiver features hot-plug support, Digital Optical Monitoring (DOM) for real-time diagnostics, and RoHS-6 compliance. It is backed by Arista's 1-Year Limited Hardware Warranty with optional Next Business Day and 4-Hour Advance Hardware Replacement support services.

FAQs

Q: What is the maximum transmission distance of the OSFP-400G-XDR4-S?
A: The OSFP-400G-XDR4-S supports parallel single-mode fibre (SMF) transmission at up to 2km, making it suitable for intra-data centre and campus spine-leaf interconnects.

Q: Does this transceiver support breakout connectivity?
A: Yes. The OSFP-400G-XDR4-S supports breakout to 4x 100GBASE-FR, enabling flexible connectivity to 100G ports or devices without additional aggregation hardware.

Q: What type of optical connector does the OSFP-400G-XDR4-S use?
A: It uses SN optical connectors, which provide a higher-density cabling solution compared to traditional MPO/MTP connectors — ideal for maximising port density in modern data centres.

Q: Is Digital Optical Monitoring (DOM) supported?
A: Yes. The transceiver supports DOM, allowing real-time monitoring of optical parameters such as transmit/receive power, temperature, and voltage for proactive diagnostics and network management.

Q: Is the OSFP-400G-XDR4-S compatible with Arista 400G switches?
A: Yes. This transceiver is designed for use in Arista 400G-capable platforms such as the 7800R3, 7500R3, and 7050CX3 series switches that feature OSFP port interfaces.

Q: Can I purchase the Arista OSFP-400G-XDR4-S in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller supplying Arista transceivers with fast delivery across Australia. Contact us or shop online for availability and pricing.
