100G QSFP28 CWDM4 optical transceiver for 2km SMF links with low power consumption.
When scaling data center interconnects beyond 100 meters, multimode fiber reaches its limit and active optical cables become cost-prohibitive. This 100G QSFP28 optical transceiver enables reliable single-mode connectivity for campus and metro deployments without replacing existing cabling infrastructure.
The LRHQ131X-02ATL delivers 100Gb/s throughput over standard SMF up to 2km using CWDM4 technology, eliminating the need for expensive dispersion compensation modules. With power dissipation under 3.5W and hot-pluggable QSFP28 form factor, it reduces cooling costs while maximizing port density in high-speed switches.
Ideal for data center interconnects and enterprise backbone upgrades, this module provides digital diagnostic monitoring for proactive maintenance. Compatible with industry-standard SFF-8665 interfaces, it ensures seamless integration into existing 100G Ethernet networks.
Supports 100Gb/s data rate links up to 2km on single-mode fiber using four CWDM wavelengths.
Power dissipation less than 3.5W with 1.5W low power mode support for energy-efficient deployments.
Hot-pluggable QSFP28 form factor compliant with SFF-8665 MSA for broad switch compatibility.
Real-time monitoring of bias current, transmit power, RSSI, voltage, and temperature per channel.
Enables 2km connectivity over standard single-mode fiber for campus and metro applications.
