Description

High-density 800G OSFP transceiver that breaks out into two independent 400G DR4 optical interfaces for scalable spine/leaf and DC fabric deployments. Each 400G port operates over parallel single-mode at 1310 nm for short-reach leaf aggregation up to 500 m per link. Ideal for migrating 400G fabrics while utilizing 800G switch ports efficiently.

Features

- 2x400G breakout from a single 800G OSFP port
- Standards-based 400GBASE-DR4 for broad interoperability
- Short-reach 1310 nm parallel SMF up to 500 m per link
- Dual MPO-12 front connections for simple structured cabling
- Hot-swappable design with real-time digital diagnostics
- Efficient 800G-to-400G migration in dense data center fabrics

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.

FAQs

Q: Can this 800G module connect to two separate 400G devices?
A: Yes. It presents two independent 400G DR4 optical ports via dual MPO-12 connectors.

Q: What cabling do I need?
A: Two parallel SMF MPO-12 trunk cables (8 fibers used per link) for the two 400G DR4 ports.

Q: Is it compatible with QSFP-DD 400G DR4 optics at the far end?
A: Yes, optical interoperability is standards-based (400GBASE-DR4), regardless of the far-end form factor.

Q: Does the host need KP4 FEC?
A: Yes. 400G DR4 relies on RS(544,514) KP4 FEC on the host side.

Q: What is the supported operating temperature?
A: 0 to +70 °C (standard temperature).

Q: Does it support DOM/DDM?
A: Yes, digital diagnostics are supported for link monitoring.
