Description

The Arista OSFP-400G-ZR is a 400GBASE-ZR digital coherent optical transceiver designed for metro data center interconnect and long-haul applications. Using advanced DP-16QAM modulation and tunable C-band DWDM wavelengths, it delivers 400 Gbps over distances up to 120 km with amplification. This pluggable OSFP DCO module complies with OIF 400ZR standards and supports point-to-point DCI links with industry-wide interoperability.

Features

Digital coherent optics (DCO) technology with advanced DSP for superior signal integrity
- Tunable C-band DWDM wavelengths for flexible DWDM grid integration
- DP-16QAM modulation for efficient 400 Gbps single-wavelength transmission
- Concatenated FEC (C-FEC) for robust error correction and extended reach
- Hot-pluggable OSFP form factor for easy deployment and maintenance
- Support for both amplified (120 km) and unamplified (80 km) transmission
- Multi-vendor interoperability via OIF 400ZR standard compliance
- Digital optical monitoring (DOM) for real-time performance tracking
- Low launch power (-10 dBm typical) optimized for metro DCI applications
- Compatible with standard DWDM Mux/Demux and EDFA optical systems
- Supports point-to-point and simple ring network topologies
- Extended operating temperature range (0°C to 70°C) for diverse environments

FAQs

Q: What is the maximum transmission distance for the OSFP-400G-ZR?
A: The OSFP-400G-ZR supports up to 120 km over single-mode fiber with optical amplification (EDFA), and up to 80 km for unamplified point-to-point links, making it ideal for metro and regional DCI applications.

Q: Is this transceiver compatible with other vendors' 400ZR modules?
A: Yes, the OSFP-400G-ZR complies with the OIF 400ZR Implementation Agreement, ensuring multi-vendor interoperability with other standards-compliant 400ZR modules and DWDM systems.

Q: What platforms support the Arista OSFP-400G-ZR transceiver?
A: The OSFP-400G-ZR is supported on specific Arista platforms including the 7060PX4-32 and other switches with OSFP ports. Refer to Arista's Transceiver and Cable Guide and the 400ZR DCI Solution Data Sheet for a complete list of compatible platforms.

Q: Can the OSFP-400G-ZR operate in unamplified DWDM networks?
A: Yes, the module can operate in unamplified point-to-point configurations up to 80 km, though external amplification extends reach to 120 km for longer metro and regional links.

Q: What is the power consumption of this module?
A: The OSFP-400G-ZR typically consumes around 12W, which is within the thermal and power limits of the OSFP form factor, making it suitable for high-density data center and routing platforms.
