Arista SFP-10G-DZ-T-Arista | 10G DWDM Tunable Transceiver, C-Band 50GHz, 80km SMF

Q: What is the primary advantage of a tunable DWDM transceiver?
A: The SFP-10G-DZ-T eliminates the need to stock multiple fixed-wavelength DWDM modules. It can be software-tuned to any ITU-T DWDM channel within the full C-Band (1528nm to 1568nm) at deployment time, significantly reducing inventory complexity and allowing flexible wavelength assignment in high-density DWDM networks.

Q: How do I configure the wavelength on Arista switches?
A: On Arista EOS-based platforms, use the 'transceiver channel' command under interface configuration mode to select the ITU channel number. You can verify supported channels with 'show interfaces transceiver channels' and confirm the programmed wavelength using 'show interfaces transceiver hardware'.

Q: What is the maximum transmission distance for this transceiver?
A: The SFP-10G-DZ-T supports links up to 80km over duplex single-mode fibre with a 23 dB optical link budget. Actual reach depends on installed plant loss, fibre quality, connectors, and splices. It is ideal for long-haul data centre interconnect and metro network deployments.

Q: Is this transceiver compatible with all Arista switches?
A: The SFP-10G-DZ-T is supported on Arista platforms with 10G SFP+ ports running current EOS releases, including 7050X, 7060X, 7280R, 7500R, and 7800R series. Always consult the Arista Transceiver and Cable Guide for specific platform compatibility and any restrictions.

Q: What DWDM channels are supported?
A: The transceiver covers the full C-Band on a 50 GHz ITU grid, providing access to a wide range of ITU-T DWDM channels. The specific channel numbers and wavelengths are listed in the Arista Transceiver Data Sheet, spanning from approximately C17 (1563.86nm) to C61 (1528.77nm).
