Description

800G OSFP transceiver with two independent 400G FR4 long-reach ports for flexible aggregation and leaf/edge uplinks. Each 400G FR4 uses 4 CWDM lanes over duplex SMF with up to 2 km reach, simplifying cabling with LC connectors while maximizing 800G port utility.

Features

- Breaks one 800G OSFP port into two independent 400G FR4 links
- 2 km reach over standard OS2 SMF using duplex LC
- CWDM4 lanes for efficient fiber utilization
- Standards-based 400GBASE-FR4 interoperability
- Integrated digital diagnostics for proactive monitoring
- Ideal for data center aggregation and campus interconnects

FAQs

Q: How many LC connections are required?
A: Two separate duplex LC connections—one for each 400G FR4 port.

Q: Can each 400G FR4 port connect to a different device?
A: Yes. The two 400G ports are independent and can terminate on separate endpoints.

Q: Is it interoperable with QSFP-DD 400G FR4 optics?
A: Yes, it interoperates optically via the 400GBASE-FR4 standard.

Q: What FEC is required?
A: RS(544,514) KP4 FEC on the host side.

Q: What environments is it suited for?
A: Leaf-spine, aggregation, and interconnects up to 2 km where duplex LC cabling is preferred.
