Description
Product Detail:
HYTOPTODEVICE Arista Networks SFP-1G-EX-40 Compatible 1000BASE-EX 1310nm 40km DDM SMF SFP Module
  The HYTOPTODEVICE Arista SFP-1G-EX-40 compatible transceiver is a premium 1.25Gbps 1000Base-EX SFP optical module engineered for extended-distance networking. Operating at a 1310nm wavelength over Single-mode Fiber (SMF), this module is specifically designed to provide high-stability connectivity for fiber spans up to 40km (24.8 miles).As a high-performance SFP-1G-EX-40 replacement, it is strictly compliant with the SFP Multi-Source Agreement (MSA) and IEEE 802.3z standards. It is 100% coded and tested to ensure seamless "plug-and-play" integration into Arista 7000 Series switches. Built for data center and mission-critical environments, the HYTOPTODEVICE variant features a commercial-grade operating temperature range (0°C to 70°C) and low power consumption, offering a cost-effective alternative for metropolitan area network (MAN) uplinks and regional campus backbones.

Compatibility and Supported Devices

   The HYTOPTODEVICE SFP-1G-EX-40 compatible SFP is rigorously verified for seamless operation with:

  • 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.

 Application Scenarios
  • 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 Arista Networks SFP-1G-EX-40 Compatible SFP Transceiver:

Q1: Is the HYTOPTODEVICE SFP-1G-EX-40 recognized by Arista EOS? A: 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)? A: 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? A: 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? A: 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? A: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
