RoHS-compliant optical module DML

RoHS compliant DML-based active optical modules are available in 100G QSFP28 form factors, supporting high-speed Ethernet links with environmentally safe materials.OverviewActive optical modules using Directly Modulated Laser (DML) technology convert electrical signals into optical signals for high-speed data transmission. RoHS compliance ensures that these modules are free from hazardous substances like lead, mercury, and cadmium, making them suitable for environmentally regulated deployments .Key FeaturesData Rate: Typically 100Gb/s for QSFP28 modules .Wavelength: DML modules often operate in the LAN-WDM range, e.g., 1295.56 nm to 1309.14 nm for 4-channel 100G QSFP28 modules .Reach: Depending on the module, DML transceivers can support up to 40 km with FEC enabled .Standards Compliance: Modules comply with QSFP MSA, IEEE 802.3ba/bm, and 4WDM-40 MSA standards .Connector Types: LC or MPO optical ports are commonly used .Applications: Data center interconnects, metropolitan area networks, and high-performance computing environments .Example ModulesINTCERA 100G QSFP28 4WDM-40 DML 40km: Converts 4 input channels of 25Gb/s electrical data to 4 LAN-WDM optical channels, multiplexed for 100Gb/s transmission. Supports up to 40 km with FEC and is RoHS compliant .Accelink RTXM420-550 QSFP28 SR4: Designed for 100G Ethernet over multimode fiber up to 100 m, RoHS compliant, and supports immersion liquid cooling applications .Advantages of DML in RoHS ModulesCompact and low-power: DML modules are smaller and consume less power than externally modulated lasers.Cost-effective: Suitable for short to medium reach applications without the need for complex modulation schemes.Environmentally safe: RoHS compliance ensures reduced environmental impact and regulatory adherence .ConsiderationsTemperature and voltage limits: Modules must be operated within specified ranges to maintain performance .Connector and fiber type: Ensure compatibility with LC or MPO connectors and single-mode or multimode fiber as required.FEC requirements: Longer reach DML modules may require forward error correction to achieve maximum distance . RoHS compliant DML active optical modules provide a reliable, environmentally friendly solution for high-speed optical networking, particularly in 100G data center and metro network applications.
