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 40km optical transceivers are fully tested and certified to work seamlessly with the following  Arista Networks equipments:

• Arista 7010 Series: 7010T-48, 7010T-48-DC.

• Arista 7050 Series: 7050SX, 7050TX, 7050QX (via QSA adapters).

• Arista 7150 Series: 7150S-24, 7150S-52, 7150S-64.

• Arista 7280 Series: High-performance routing and switching platforms.

• Arista 7300 Series: Modular chassis systems using SFP-compatible line cards.
  
  

Main Application Scenarios of Fiber Connection Module

• Metropolitan Data Center Interconnect (DCI): Linking remote Arista-based data center racks across a city or regional span up to 40km.

• Carrier-Grade Backhaul: Providing reliable 1.25G fiber handoffs for service providers where standard 10km (LX) reach is insufficient.

• Enterprise Campus Core Uplinks: Connecting distributed buildings to a central Arista core switch using high-power 1310nm single-mode infrastructure.

FAQ for Transceiver Module

Q1: Is the HYTOPTODEVICE SFP-1G-EX-40 recognized by Arista EOS?
A1: Yes. Our modules are flashed with the correct Arista EEPROM signatures, ensuring they are identified as genuine and compatible by Arista EOS (Extensible Operating System) without the need for specialized "unsupported" commands.

Q2: Does this module support Digital Optical Monitoring (DOM)?
A2: Absolutely. It features full DOM/DDM support, allowing you to monitor real-time diagnostics like laser temperature, supply voltage, and optical power via the bash or show inventory commands in EOS.

Q3: Can I use this in an Arista 10G SFP+ port?
A3: Yes. Most Arista 10G SFP+ ports are dual-speed and backward compatible with 1G SFP modules. Simply insert the module, and the port will typically auto-negotiate to 1Gbps.

Q4: Do I need to use an optical attenuator for short-range links?
A4: For fiber links shorter than 5km, we recommend using a 10dB LC optical attenuator. The SFP-1G-EX-40 uses a high-power laser that may over-saturate the receiver at close range.

Q5:Arista Networks SFP-1G-EX-40 not working？
A5:Follow these quick steps:

1. Check DDM: Run show transceiver detail on the switch. Look for Low Rx Power or faults.

2. Clean & Reseat: Clean the LC fiber connectors and firmly re-seat the SFP module.

3. Verify Fiber: Ensure you are using a single-mode (SMF) patch cable. Check for bends or breaks.

4. Swap Test: If possible, test the SFP in a different port or swap it with a known-working module to isolate the fault.

If DDM shows "Low Tx Power" or "Fault", the module is likely defective and needs replacement

Q6:How to choose the right 1g 40km optical transceiver?
A6:(1)Confirm transmission distance needs:for links greater than 20 kilometers and less than 40 kilometers，1000BASE-EX  SFP transceiver is the most cost-effective choice.(2)match device brand and port type:confirm the switch brand and port specification before purchase to ensure the transceiver is fully compatible and avoid compatibility risks;(3)Balance performance and budget:compared with expensive OEM original modules, qualified third-party 1.25g sfp ex transceiver can reduce costs by 70%-90% while maintaining the same performance.
