The High Power DFB External Modulated Laser Optical Transmitter-ELDX Series is engineered to deliver precise, high-fidelity optical signals across demanding industrial and defense environments. By providing exceptionally stable wavelength control and high-power output, this transmitter module becomes a critical component for advanced optical networks, ensuring that vital data is transmitted without interruption or distortion. When integrating these transmitters into your infrastructure, engineers will immediately notice the low noise floor and the exceptional stability of the optical carrier, which are fundamental for high-end applications.
• Fiber optic sensing: In complex sensing environments, the ELDX series ensures precise signal integrity. The distinct absence of mode-hopping during tuning allows for accurate environmental data collection, which is crucial for structural health monitoring, oil pipeline leakage detection, and perimeter security where every micro-strain or temperature shift matters. The clean signal output translates directly to higher resolution in sensory data.
• Fiber communication: Designed to handle high-capacity data loads, this transmitter supports long-haul and metro communication networks. The smooth optical output minimizes signal degradation over extended distances, ensuring reliable data transmission without the need for constant inline amplification. This efficiency reduces overall network latency and lowers the total cost of ownership for network operators managing massive data throughput.
• Radar system: For defense and aerospace applications, the transmitter provides the low phase noise and high dynamic range required for modern radar arrays. The durable construction withstands intense vibrations and extreme thermal cycles, maintaining lock-on precision when tracking fast-moving targets. The immediate response time of the laser modulation ensures that radar pulses remain sharp and distinct, enhancing target resolution.
• Microwave photonic transmission system: Directly connecting the radio frequency and optical domains, the ELDX series enables high-frequency analog signal transport. The co-planar design of electrical inputs and optical outputs simplifies integration into existing standard mounts and drivers, facilitating clear, low-distortion microwave photonics operations for satellite communications and advanced electronic warfare systems.
The ELDX Series is built upon an advanced Distributed Feedback (DFB) structural design, engineered to eliminate mode-hopping risks while delivering a smooth, consistent performance across a wide tuning range. Every aspect of its physical and electronic architecture is optimized for long-term reliability, minimal maintenance, and straightforward integration into complex optical infrastructures. The meticulous engineering behind the ELDX Series ensures that each unit performs consistently under continuous operation.
• Output power of up to 63mw: This substantial power delivery ensures consistent signal strength across extensive fiber runs, significantly reducing the dependency on supplementary inline amplifiers. The stable, high-intensity output maintains signal clarity even in dense, multi-channel transmission environments, allowing for wider optical splitting ratios and extended network reach without compromising data integrity.
• 14-pin butterfly package: Encased in a heavy-duty, industrial-grade hermetic housing, the module physically protects delicate internal laser diodes and optical alignments from moisture ingress, dust accumulation, and mechanical shock. The cool, metallic finish of the casing provides excellent thermal conductivity, while the standardized footprint allows for straightforward mounting, soldering, and thermal management on densely populated printed circuit boards.
• ITU standard wavelength options: By adhering to strict International Telecommunication Union grids, the transmitter guarantees immediate compatibility with existing dense wavelength-division multiplexing (DWDM) equipment and network infrastructure. This precise standardization eliminates the need for custom tuning or costly network retrofits, allowing engineers to deploy the modules rapidly into active telecom environments.
• Operating temperature range is -55~70℃: Equipped with an integrated Thermoelectric Cooler (TEC) and a highly responsive precision thermistor, the module actively manages its internal climate. This continuous thermal regulation ensures exact wavelength control and unwavering reliability, whether the unit is deployed in freezing high-altitude aviation environments, unconditioned outdoor telecom cabinets, or heat-intensive industrial manufacturing facilities.
Beyond the core optical performance, the ELDX Series represents a commitment to enduring reliability and adaptable engineering. We understand that advanced photonic applications often require more than just standard specifications; they demand rigorous quality assurance and the flexibility to meet unique project parameters. By maintaining strict oversight over the entire production lifecycle—from semiconductor wafer processing to final hermetic sealing—we ensure that every transmitter meets the exact tolerances required for mission-critical deployments.
Every optical transmitter undergoes rigorous testing protocols aligned with industrial-grade manufacturing standards, referencing ISO 9001 quality systems. We provide comprehensive warranties covering material and craftsmanship defects, ensuring long-term operational stability and mitigating procurement risks for large-scale network deployments. The tactile solidity of the hermetic sealing, the flawless finish of the optical pigtail, and the precision-machined electrical pins all reflect our uncompromising commitment to physical durability and continuous performance. This end-to-end quality control translates directly to fewer field failures and lower maintenance costs.
Backed by a mature, vertically integrated manufacturing infrastructure, our engineering capabilities extend far beyond standardized solutions. While the ELDX Series offers a highly reliable, high-power foundation, we provide flexible customization services tailored to specific operational demands. Whether a project requires unique wavelength tuning outside standard grids, specialized fiber pigtail lengths and connector types, or integration with complex peripheral network devices, our dedicated R&D team collaborates closely with procurement engineers to deliver exact specifications without compromising the rapid deployment timeline.
