100G QSFP28 ER4 optical module is an optical transceiver solution designed for long-distance, high-performance data communication. Housed in a standard QSFP28 form factor, it achieves transmission distances of up to 40 kilometers over single-mode fiber, perfectly addressing the core demands for high bandwidth and extended reach in scenarios such as Metropolitan Area Networks (MANs), Data Center Interconnects (DCI), and 5G backhaul.
| Product Features: |
●High speed I/O electrical interface (CAUI-4) compliant with IEEE 802.3bm-2015 ●Compliant with 100GBASE-ER4 Lite standard ●Single 3.3V Supply Voltage ●Maximum power consumption 5.5 W at 70ºC Case Operating Temperature ●LAN WDM EML laser and APD Receiver ●Universal QSFP28 MSA package with duplex LC connector ●Two Wire Serial Interface with Digital Diagnostic Monitoring ●Complies with EU Directive 2011/65/EU (RoHS compliant) ●Class 1 Laser |
●Compliant with QSFP28 Standard:SFF-8661 Rev 2.5, SFF-8636 Rev 2.10aThe key strengths of this module lie in its high performance and integration. It supports 4-channel full-duplex transmission, with each channel operating at speeds up to 25.78 Gbps, aggregating into a 100G high-speed link over a single fiber using Coarse Wavelength Division Multiplexing (CWDM) technology. With a typical power consumption of less than 4.5 watts and featuring Digital Diagnostic Monitoring (DDM), it enables real-time performance monitoring and troubleshooting, significantly enhancing network manageability and operational efficiency.
