What is the maximum transmission distance supported by the 100GBASE-LR4 QSFP28 transceiver?

This 100GBASE-LR4 QSFP28 module is specifically designed to support a maximum link length of 10 kilometers over standard Single Mode Fiber (SMF) without requiring external amplification.

Is the Allied Telesis QSFP28-LR4 Compatible LINK-PP compatible with my existing Cisco or Juniper network switches?

Yes, the 100GBASE-LR4 QSFP28 is fully compliant with the QSFP28 MSA technical specifications, ensuring seamless plug-and-play interoperability with major equipment vendors like Cisco, Juniper, and Arista.

Does this 100GBASE-LR4 QSFP28 transceiver support Digital Diagnostic Monitoring (DDM)?

Absolutely, it features comprehensive DDM functions accessible via the I2C interface as specified by SFF-8636, allowing real-time monitoring of temperature, optical transmit/receive power, and voltage.

What type of laser technology does the 100GBASE-LR4 QSFP28 use to achieve its 10km reach?

The module utilizes a high-performance 4x25Gb/s DFB-based LAN-WDM transmitter, which provides excellent wavelength stability and minimizes chromatic dispersion over the 10km optical link.

Is the QSFP28-LR4 compatible with standard QSFP28 ports?

It is designed for compatible QSFP28 host systems that support 100GBASE-LR4 optical modules. Final compatibility should always be confirmed against the host platform’s approved vendor list and port requirements.
