Description

The Arista LPO-800G-2FR4 is an 800G Linear Pluggable Optic (LPO) OSFP transceiver delivering dual 400GBASE-FR4 connectivity over single-mode fibre. Designed for high-density data centre interconnects and spine-leaf fabric deployments, this transceiver leverages Linear Drive technology to eliminate the DSP retimer, reducing power consumption and latency compared to traditional coherent or retimed solutions. Its OSFP form factor supports the latest generation of 800G-capable switching and routing platforms, making it ideal for hyperscale and enterprise data centre operators scaling beyond 400G.

Compatible with Arista 800G-capable switches and routers, the LPO-800G-2FR4 uses 1310 nm CWDM4 FR4 optics on each 400G lane pair, supporting reach up to 2 km over OS2 single-mode fibre. The dual-port design enables breakout configurations to two independent 400G links, maximising port density and flexibility.

FAQs

Q: What does 'Linear Pluggable Optic' (LPO) mean, and why does it matter?
A: LPO transceivers omit the Digital Signal Processor (DSP) retimer found in conventional optical modules. This results in lower power draw, reduced latency, and a simpler signal path — key advantages in high-density, power-constrained data centre environments running 800G fabrics.

Q: What fibre type and maximum reach does the LPO-800G-2FR4 support?
A: The LPO-800G-2FR4 operates over OS2 single-mode fibre and supports a maximum reach of approximately 2 km, consistent with the 400GBASE-FR4 standard on each of its two 400G channels.

Q: Can this transceiver be used for breakout to two separate 400G links?
A: Yes. The dual 400GBASE-FR4 design allows the single OSFP module to break out into two independent 400G connections, enabling flexible cabling topologies and maximising port density on 800G-capable Arista platforms.

Q: Which Arista platforms is the LPO-800G-2FR4 compatible with?
A: This transceiver is designed for Arista switches and routers featuring 800G OSFP ports. Typical platforms include Arista's 7800R3 and 7700R series data centre switches. Verify compatibility with your specific Arista platform's compatibility matrix or contact IP Trading for guidance.

Q: Can I purchase the Arista LPO-800G-2FR4 in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware specialist stocking Arista transceivers and networking equipment. Contact the team for pricing, lead times, and volume purchasing options.

Q: How does 800G LPO compare to traditional 800G DR8 or 2xFR4 coherent solutions?
A: LPO-based FR4 transceivers like the LPO-800G-2FR4 offer lower power and cost compared to DSP-based coherent optics, and are optimised for intra-data-centre reaches up to 2 km. Coherent solutions are better suited for longer-reach or metro interconnects, while LPO excels in high-density, short-to-medium reach switching fabrics.
