QSFPTEK 100G QSFP28 Transceiver Module User Manual

1. Увод

The QSFPTEK 100G QSFP28 Transceiver Module (Model: QT-QSFP28-LR4-Cisco) is a high-performance, hot-pluggable optical module designed for 100 Gigabit Ethernet applications. It provides a reliable solution for high-speed data transmission over single-mode fiber, compatible with Cisco QSFP-100G-LR4-S and other open switches. This module supports a 100Gb/s data rate and features an LC duplex connector for efficient network integration.

Key features include four LAN Wavelength Division Multiplexing (LWDM) lanes at 1295nm, 1300nm, 1305nm, and 1309nm, enabling data transmission up to 10 kilometers. Digital Diagnostic Monitoring (DDM) functionality is integrated to provide real-time monitoring of critical operational parameters.

2. Подешавање

This QSFP28 transceiver module is designed for plug-and-play operation and is hot-pluggable, allowing for installation or removal without powering down the host equipment.

2.1 Кораци инсталације

1. Проверите компатибилност: Ensure your network switch or host device has a compatible QSFP28 port. This module is specifically designed for Cisco QSFP-100G-LR4-S and other MSA-compliant open switches.
2. Prepare the Module: Carefully remove the transceiver module from its protective packaging. Ensure the optical ports are clean and free of dust.
3. Убаците модул: With the blue pull tab facing upwards, gently slide the QSFP28 module into the designated QSFP28 port on your network device until it clicks into place. Ensure it is fully seated.
4. Повежите оптичке каблове: Remove the dust caps from the LC duplex ports on the transceiver and from your fiber optic cables. Connect the appropriate single-mode LC duplex fiber optic cables to the module's ports. Ensure a secure connection.
5. Verify Link Status: Check the link status indicators on your network device to confirm that the module is properly recognized and a stable optical link has been established.

3. Оперативни

Once installed and connected, the QSFPTEK 100G QSFP28 Transceiver Module operates automatically to establish and maintain a 100 Gigabit Ethernet link. The module supports Digital Diagnostic Monitoring (DDM), which provides real-time access to device operating parameters.

3.1 Дигитално дијагностичко праћење (DDM)

DDM functionality allows network administrators to monitor critical information about the transceiver's performance and identify potential issues proactively. Accessible through the host device's management interface, DDM provides data on:

• Laser Bias Current: Indicates the current supplied to the laser.
• Суппли Волtage: Волtage supplied to the module.
• Transmitted Optical Power: The power of the optical signal being sent by the module.
• Module Temperature: The internal operating temperature of the transceiver.
• Received Optical Power: The power of the optical signal received by the module.

Monitoring these parameters helps ensure optimal performance and aids in troubleshooting.

4. Одржавање

The QSFPTEK 100G QSFP28 Transceiver Module is designed for minimal maintenance. Adhering to the following guidelines will help ensure its longevity and optimal performance:

• Одржавајте конекторе чистим: Always ensure that the optical connectors on both the transceiver and the fiber optic cables are clean. Dust and contaminants can significantly degrade optical performance. Use appropriate fiber optic cleaning tools if necessary.
• Пажљиво рукујте: Avoid physical shock or excessive force when handling the module. Do not bend or twist the fiber optic cables sharply.
• Чувајте правилно: When not in use, store the module in its original protective packaging with dust caps installed to prevent damage and contamination.
• Услови животне средине: Operate the module within the specified temperature range (0℃ to +70℃) to prevent overheating or performance degradation.

КСНУМКС. Решавање проблема

If you encounter issues with your QSFPTEK 100G QSFP28 Transceiver Module, consider the following troubleshooting steps:

5.1 Уобичајена питања и решења

• No Link or Link Flapping:
  • Check Module Seating: Ensure the QSFP28 module is fully inserted and latched into the host port.
  • Inspect Fiber Cables: Verify that the LC duplex fiber optic cables are correctly connected and not damaged.
  • Чисти конектори: Contaminated fiber connectors are a common cause of link issues. Clean both the module's ports and the fiber cable connectors.
  • Проверите компатибилност: Confirm that the module is compatible with your host device and the connected fiber type (single-mode).
• Low Signal Strength or High Bit Error Rate (BER):
  • Check DDM Parameters: Use DDM to monitor Transmitted and Received Optical Power. Compare values against the module's specifications.
  • Дужина оптичког кабла: Ensure the fiber cable length does not exceed the module's maximum supported distance (10km for LR4).
  • Fiber Quality: Inspect fiber optic cables for bends, kinks, or damage that could cause signal loss.
  • Чистоћа конектора: Re-clean all optical connectors.
• Module Not Recognized by Host:
  • Re-seat Module: Remove and re-insert the module firmly.
  • Check Host Port: Ensure the QSFP28 port on the host device is enabled and functioning correctly.
  • Фирмвер: Ensure the host device's firmware is up-to-date and supports 100G QSFP28 modules.

If issues persist after performing these steps, please contact QSFPTEK technical support for further assistance.
