Description

The Arista OSFP-400G-XDR4 is a 400G XDR4 OSFP transceiver designed for high-density data centre interconnects and campus core deployments requiring breakout capability. Operating as four independent 100GBASE-FR lanes over parallel single-mode fibre, it supports link distances up to 2km via an MPO-12 APC connector — making it ideal for inter-building runs, spine-to-leaf breakout configurations, and 400G to 4x100G fan-out architectures. Its OSFP form factor delivers the port density and power efficiency demanded by modern 400G switching platforms.

Compatible with Arista 400G-capable switches and routers, this transceiver supports both native 400G operation and 4x100G breakout mode using an MPO-12 APC to 4x LC duplex breakout cable, providing flexible deployment options across existing SMF plant. Order direct from iptrading.com.au — Australian-owned and operated since 2001.

Features

- 400G XDR4 MSA-compliant OSFP transceiver for Arista 400G platforms
- 4x 100GBASE-FR lanes over parallel SMF — supports native 400G and 4x100G breakout
- MPO-12 APC connector for low-loss connectivity over existing SMF infrastructure
- Up to 2km reach — ideal for inter-building, campus core, and extended data centre links
- PAM4 modulation for efficient high-speed signal transmission
- Hot-swappable OSFP form factor for high-density port configurations
- Compatible with standard MPO-12 APC to 4x LC duplex breakout cables for fan-out deployments

FAQs

Q: What is the maximum transmission distance of the OSFP-400G-XDR4?
A: The OSFP-400G-XDR4 supports link distances of up to 2km over parallel single-mode fibre (PSMF), making it suitable for inter-building and campus core connections.

Q: Can this transceiver be used in 4x100G breakout mode?
A: Yes. Using an MPO-12 APC to 4x LC duplex breakout cable, the OSFP-400G-XDR4 can operate as four independent 100GBASE-FR lanes, enabling flexible 4x100G fan-out to downstream devices.

Q: What fibre type and connector does the OSFP-400G-XDR4 require?
A: This transceiver uses an MPO-12 APC connector and requires parallel single-mode fibre (PSMF). Note the APC (angled physical contact) polish — ensure your patch cables and MPO cassettes are APC-compatible to avoid insertion loss.

Q: Which Arista platforms is the OSFP-400G-XDR4 compatible with?
A: The OSFP-400G-XDR4 is designed for Arista switches and routers with OSFP-based 400G ports, such as the Arista 7800R3 and 7500R3 series. Always verify compatibility with your specific platform and EOS version.

Q: How does XDR4 differ from DR4 or FR4 400G transceivers?
A: 400G-XDR4 uses MPO-12 parallel SMF (4 fibres TX, 4 fibres RX) and supports up to 2km — longer than DR4 (500m) but using parallel rather than WDM optics. FR4 uses duplex LC with CWDM4 wavelengths. XDR4 is optimised for extended parallel SMF runs with breakout flexibility.

Q: Can I purchase the Arista OSFP-400G-XDR4 in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian-owned and operated IT hardware reseller serving B2B customers since 2001. Contact us for pricing, stock availability, and volume purchasing options.
