Engineered for robust high-speed networks, this module serves as an advanced alternative to standard 100G QSFP28 LR4 optics by extending the reliable transmission reach to 20km over single-mode fiber. It features a hardened industrial temperature range and utilizes precise LAN-WDM grids, making it highly ideal for demanding telecommunications and edge computing environments.
Delivering industrial-grade reliability, this transceiver provides extended 20km reach capabilities, offering a highly resilient solution for network architectures typically relying on standard 100G QSFP28 LR4 modules.
Providing massive bandwidth capacity, this module ensures ultra-low latency and seamless data aggregation required for next-generation mobile infrastructure. Its robust design maintains stable 100Gbps throughput even in outdoor, non-climate-controlled telecom enclosures.
Utilizing Local Area Network Wavelength Division Multiplexing, this transceiver multiplexes four distinct wavelengths onto a single fiber pair. This significantly maximizes existing fiber plant utilization while minimizing signal dispersion over extended optical links.
Operating on the precise IEEE 802.3ba LAN-WDM grid, these tightly spaced optical channels ensure minimal chromatic dispersion. This precise wavelength assignment guarantees optimal signal integrity and compliance with high-speed transmission standards.
Designed with high-sensitivity receivers and powerful optical lasers, this 100G QSFP28 LR4 module effortlessly bridges distances up to 20 kilometers on standard single-mode fiber. It provides superior link budgets for metropolitan area networks and extended campus connectivity.
Equipped with an industry-standard duplex LC optical receptacle, this module ensures seamless integration into existing high-density patching environments. The secure latching mechanism provides reliable, low-insertion-loss physical connections for critical data routing.
Built-in Digital Optical Monitoring allows network administrators to proactively track critical parameters such as temperature, optical transmit and receive power, and laser bias current. This facilitates predictive maintenance and minimizes network downtime.
