Full Compatibility List and Supported Devices of Fiber Optic Transceiver
One of the biggest advantages of third-party optical transceiver is their strong brand compatibility,which helps enterprises cut hardware costs without sacrificing performance.Our 1G SFP 120km optical transceivers are fully tested and certified to work seamlessly with the Arista equipments:
Arista 7010T Series: DCS-7010T-48, DCS-7010T-48-DC
Arista 7050X & 7050X3 Series: DCS-7050SX3-48YC12, DCS-7050TX3-48C8, DCS-7050QX-32S (configured in multi-rate/1G mode)
Arista 7150S Series: DCS-7150S-24, DCS-7150S-52, DCS-7150S-64
Arista 720XP Series (Campus PoE Switches): DCS-720XP-48Y6, DCS-720XP-24ZY4
Arista 7280R & 7280R3 Series: DCS-7280SR-48C6, DCS-7280QR-C36
Main Application Scenarios of Fiber Connection Module
Extreme Long-Reach Cloud Interconnect: Linking remote private cloud instances, disaster recovery centers, or geographically isolated edge nodes back to a centralized Arista data center matrix.
Regional & Metro Transport Backhaul: Allowing internet service providers (ISPs) to deploy Arista switching architectures for backhauling 1G traffic from deep rural broadband networks or outlying municipal point-of-presence (PoP) hubs.
Critical Utilities & Pipeline Telemetry: Powering long-distance backbone communications for sprawling infrastructure projects such as oil/gas pipelines, regional rail systems, and smart electrical grids.
Geographically Separated Multi-Campus Links: Connecting distinct state university sites or massive corporate regional branches spanning up to 120km apart.
Q1: What is the maximum distance supported by the Arista SFP-1G-EZX-120 compatible optic? A1: It supports a maximum link distance of up to 120 kilometers (approx. 74.5 miles) over high-quality single-mode fiber (SMF).
Q2: Will Arista EOS accept this compatible transceiver without throwing warnings?
A2: Yes. Our transceivers are pre-coded with precise Arista hardware identification signatures, allowing them to register natively as original optics without requiring any system override hacks.
Q3: Do I need an optical attenuator when deploying this module on a short fiber path?
A3: Yes, absolutely. Because the transmitter generates strong optical signals and the APD receiver is highly sensitive, connecting this module on links shorter than 50-60km without a 15dB to 20dB inline optical attenuator will permanently damage or burn out the receiver.
Q4: What is the receiver overload threshold for the SFP-1G-EZX-120?
A4: The receiver overload is rated at -10 dBm. Any incoming optical signal stronger than this risks over-saturating and ruining the photodiode.
Q5: What center operating wavelength does this transceiver use?
A5: It operates at a 1550nm center wavelength to utilize the lowest possible attenuation spectrum window of single-mode optical fiber.
