Alcatel-Lucent  SFP-GIG-LH40 Compatible 1000BASE-EX SFP Optical Transceiver Module | HYTOPTODEVICE

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 1.25G SFP 40km optical transceivers are fully tested and certified to work seamlessly with the following  Alcatel-lucent equipments:

• Alcatel-Lucent OmniSwitch Series: OS6450, OS6850E, OS6860, OS6900, OS9000.

• Alcatel-Lucent (Nokia) Service Routers: 7750 SR series, 7450 ESS, 7210 SAS.

• Alcatel-Lucent Enterprise (ALE) Gateways: Various hardware requiring Gigabit LH SFP connectivity.
  
  

Main Application Scenarios of Fiber Connection Module

• Campus-to-Campus Fiber Links: Connecting large university or hospital campuses across distances up to 40km.

• Metropolitan Area Networks (MAN): Providing high-bandwidth fiber uplinks for regional government or enterprise networks where standard 10km modules fail.

• Service Provider Backhaul: Reliable 1.25G fiber handoffs for carrier-grade infrastructure over long-reach single-mode fiber.

FAQ for Transceiver Module

Q1: Is the HYTOPTODEVICE SFP-GIG-LH40 recognized by Alcatel-Lucent AOS software?
A1: Yes. Our modules are flashed with the correct Alcatel-Lucent EEPROM signatures, ensuring they are identified as genuine and compatible without any "unsupported transceiver" errors in the AOS (OmniSwitch) or TiMOS (Service Router) CLI.

Q2: Does this 1G LH40 module support Digital Optical Monitoring (DOM)?
A2: Absolutely. It features full DOM/DDM support, allowing network administrators to monitor real-time diagnostics like laser temperature, supply voltage, and optical power through the management console.

Q3: Do I need an attenuator for short-distance connections?
A3: For fiber links under 5km, we recommend using a 10dB LC attenuator to prevent the high-power receiver from being over-saturated, ensuring the longevity of the transceiver.

Q4: Is this module hot-swappable?
A4: Yes. You can insert or remove the HYTOPTODEVICE SFP-GIG-LH40 while the switch is powered on without affecting other network services.

Q5:Why is Alcatel-Lucent SFP-GIG-LH40 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 1.25g 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.
