Description

The Arista QDD-400G-ZRP2 is a 400GBASE-ZR+ QSFP-DD Digital Coherent Tunable Transceiver designed for high-capacity data centre interconnect (DCI) and metro IP-over-DWDM applications. OpenZR+ MSA 2.0 compliant, it delivers multi-vendor interoperability across full C-Band DWDM wavelengths with reach up to 120km over amplified single-mode fibre. Configurable as Dual 100 Gigabit Ethernet (2x100G), it supports flexible modulation formats including 400G DP-16QAM, 300G DP-8QAM, 200G DP-QPSK, and 100G DP-QPSK for adaptive capacity and reach optimisation.

Built on a coherent DSP ASIC with an ultra-narrow linewidth tunable laser, the QDD-400G-ZRP2 integrates high-speed modulators, high-responsivity coherent receivers, and Digital Optical Monitoring (DOM) for real-time visibility into operating parameters. Fully RoHS compliant and compatible with OIF-400ZR and QSFP-DD Hardware Rev6.3 standards, this transceiver suits access, edge, core, and DCI deployments requiring scalable, open-standard coherent optics.

FAQs

Q: What is the maximum reach of the Arista QDD-400G-ZRP2 transceiver?
A: The QDD-400G-ZRP2 supports reach up to 120km over amplified single-mode fibre using EDFA (Erbium-Doped Fibre Amplifier) infrastructure, making it well suited for metro and regional data centre interconnect links.

Q: Is the QDD-400G-ZRP2 compatible with non-Arista equipment?
A: Yes. The QDD-400G-ZRP2 is OpenZR+ MSA 2.0 compliant, enabling multi-vendor interoperability with any network equipment that supports the OpenZR+ standard. This open-standard compliance is a key differentiator for mixed-vendor DWDM deployments.

Q: What modulation modes and data rates are supported?
A: The transceiver supports flexible line-side modulation including 400G DP-16QAM, 300G DP-8QAM, 200G DP-QPSK, and 100G DP-QPSK. This allows network operators to trade off capacity and reach depending on link conditions and DWDM system margins.

Q: What port configuration is required on the host switch or router?
A: The QDD-400G-ZRP2 is configured as Dual 100 Gigabit Ethernet (2x100G). The host device must have a QSFP-DD port that supports 2x100G breakout mode. Verify compatibility with your specific Arista or third-party platform before deployment.

Q: What wavelength range does the transceiver support?
A: The QDD-400G-ZRP2 is tunable across the full C-Band DWDM spectrum, giving network planners maximum flexibility to assign and optimise wavelength channels in existing DWDM line systems.

Q: Can I purchase the Arista QDD-400G-ZRP2 in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller supplying Arista transceivers and networking hardware across Australia. Contact us for pricing, availability, and fast local delivery.
