Engineered for high-density interconnects, this 800Gb/s QSFP-DD optical module integrates advanced EML transmitters and PIN photo-detectors with sophisticated DSP technology. It supports 500m transmission over SMF, features built-in Digital Optical Monitoring (DOM), complies with CMIS 5.0 standards, and operates within a commercial temperature range with low overall power consumption.
This hot-pluggable 800GBASE-DR8 transceiver module delivers exceptionally reliable data transmission across enterprise networks. Utilizing a standard QSFP-DD Type 2A form factor, it seamlessly bridges high-bandwidth switches and routers while maintaining optimal thermal dissipation and power efficiency.
Tailored for artificial intelligence, machine learning, and cloud computing infrastructures, this 800G optical transceiver provides scalable, massive bandwidth. It optimizes spine-to-leaf network topology, drastically reduces cable complexity, and maximizes throughput for data-intensive server clusters.
Equipped with eight parallel 1310nm optical channels, the transceiver leverages Electro-absorption Modulated Lasers (EML) to generate clean PAM4 optical signals. This specific wavelength configuration minimizes dispersion penalty and ensures stable, jitter-free signal propagation across optical links.
Designed to support reach distances up to 500 meters over OS2 single-mode fiber, this 800G optical solution is ideal for intra-datacenter links. It delivers reliable high-speed data transfer across rows and racks without signal attenuation issues.
Featuring a male MPO-16/APC optical connector, the module enables seamless parallel optics connectivity over 16-fiber cabling. The angled physical contact (APC) endface significantly lowers back reflections, preserving superior optical return loss and transmission quality.
Integrated Digital Optical Monitoring (DOM) capabilities provide real-time telemetry, including TX/RX optical power, laser bias current, module operating temperature, and supply voltage. Network administrators can proactively monitor link health and prevent unexpected downtime.
The LINK-PP LQD-M31800-DR8C transceiver strictly conforms to international regulatory standards, ensuring eco-friendly material construction, operational safety, and high electromagnetic compatibility across enterprise data center installations worldwide.
Every optical transceiver undergoes a rigorous multi-stage quality assurance testing program, validating physical structural integrity, parametric optical performance, and long-term signal reliability prior to factory shipment.
This 800G module is fully certified under CE, FCC, UKCA, UL, REACH, and RoHS compliance frameworks, guaranteeing environmental protection, electrical isolation, and premium manufacturing standards.
Programmed and rigorously verified on major networking switches and routers, this module guarantees plug-and-play interoperability, error-free host port recognition, and seamless integration into diverse multi-vendor environments.
Comprehensive factory testing guarantees optimal QSFP-DD optical performance, ensuring high operational reliability, signal purity, and continuous data transmission under demanding network conditions.
Spectral analysis verifies precise 1310nm central wavelength alignment and side-mode suppression ratio standards.
High-speed optical eye diagram testing evaluates low transmitter jitter and clear PAM4 signal open eyes.
BERT validation ensures error-free optical data transmission before Forward Error Correction thresholds are exceeded.
Thermal cycling tests confirm stable laser performance across commercial operating temperatures from 0°C to 70°C.
Our specialized packaging and logistics procedures guarantee that every 800G optical module arrives safely, securely, and fully protected against external transport hazards.
Each optical transceiver is individually sealed inside ESD anti-static packaging bags.
Custom foam cushioning protects sensitive optical components from transit impact and vibration.
Streamlined warehouse processing ensures quick fulfillment and prompt dispatch of orders.
Reliable international express shipping offers tracked, fast delivery worldwide to customers.
Inserting the hot-swappable module into a QSFP-DD host port is straightforward. Once connected via MPO-16/APC fiber cabling, built-in auto-negotiation and CMIS management establish stable 800G links instantly, providing active link status feedback via host interfaces.
