The HYTOPTODEVICE Arista Networks SFP-1G-EZX-120 compatible SFP is rigorously verified for the following platforms:
Arista 7010 Series: Ideal for 1G high-density copper and fiber aggregation.
Arista 7050 & 7060 Series: Optimized for 1G management port connectivity on high-speed leaf/spine switches.
Arista 7280 Series: Seamlessly works with deep-buffer switches for long-haul routing.
EOS Recognition: Precision-coded by HYTOPTODEVICE to ensure native recognition by Arista EOS. The module will show as "Arista Networks" in the inventory, ensuring full DDM functionality and avoiding "Unknown Transceiver" status.
Metropolitan Backbone: Connecting disparate corporate headquarters or data centers across a city-wide reach via 120km Gigabit Ethernet SFP links.
Carrier Edge-to-Core: Providing a stable 1550nm SFP for ISP backhaul 120km links in telecommunications infrastructure.
Real-time Link Diagnostics: Integrated DDM/DOM allows for monitoring laser power and temperature directly from the Cisco CLI, essential for maintaining 120km SFP reliability.
Compliance: A Class 1 FDA Laser Safety certified SFP transceiver for Cisco, adhering to global environmental standards as a RoHS compliant 1550nm 120km SFP.

Q: Will this 1G module work in a 10G SFP+ port on an Arista 7050X?
A: Yes, most Arista SFP+ ports support dual-speed (1G/10G). The HYTOPTODEVICE module is coded to initiate the 1G link automatically.
Q: Is an attenuator required?
A: Mandatory Warning: Because of the extremely high transmit power, you must use a 15dB - 20dB optical attenuator if testing on fiber spans shorter than 50km to prevent burning out the high-sensitivity APD receiver.
Q: Does it support IEEE 802.3ah?
A: Absolutely. It is fully Compliant to IEEE 802.3ah Gigabit Ethernet, which is the standard for long-reach Ethernet deployments.
