Engineered for precision, this LR4 transceiver supports four laser channels and uses dense wavelength-division multiplexing (DWDM) to deliver reliable, low-latency data transmission across enterprise and data center networks. The module is compact, hot-swappable, and compatible with standard QSFP28 port infrastructures, enabling scalable uplinks and efficient network architecture. Ideal for core, aggregation, and spine-leaf deployments, it helps organizations maximize bandwidth while minimizing footprint and power consumption. This transceiver is backed by Ubiquiti’s engineering and quality standards, providing robust performance for high-speed network backbones and data-intensive workloads.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTechnical Specification\u003c\/strong\u003e\u003cbr\u003e- Form factor: QSFP28\u003cbr\u003e- Interface: 100 Gbps Ethernet\u003cbr\u003e- Reach: LR4 (long-reach single-mode fiber)\u003cbr\u003e- Wavelength channels: four wavelengths for 4x25 Gbps traffic per optical lane\u003cbr\u003e- Fiber type: single-mode fiber (SMF)\u003cbr\u003e- Compliance: standard QSFP28 MSA\u003cbr\u003e- Wavelength compatibility: appropriate for LR4 transmission over SMF\u003cbr\u003e- Data rate: 100 Gbps aggregate\u003cbr\u003e- Transmission distance: specified by LR4 over SMF and linked fiber plant (exact distance not provided)\u003cbr\u003e- Connector type: LC (commonly used for QSFP28 LR4 in SMF links)\u003cbr\u003e- Thermal design: hot-swappable transceiver with standard operating temperature range\u003cbr\u003e- Fiber compatibility: optimized for Ubiquiti and partner network environments\u003cbr\u003e- Power consumption: typical and maximum values not provided\u003cbr\u003e- Digital diagnostics: supports standard PnP and DMI\/monitoring features (if supported by host)\u003cbr\u003e- Management: supports standard QSFP28 management interface\u003cbr\u003e- MTBF and reliability: not specified\u003cbr\u003e\u003cbr\u003eNote\u003cbr\u003eThe product description and technical specification should be verified on the vendor's website to ensure the latest information.","brand":"Ubiquiti","offers":[{"title":"Default Title","offer_id":54820810293571,"sku":"EA8100846900006","price":409.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0338\/7647\/6043\/files\/8100846900006_1.png?v=1789686542","url":"https:\/\/itradecenter.store\/products\/ubiquiti-u-fiber-qsfp28-optical-module-single-mode-100-gbps-lr4","provider":"iTradeCenter.Store","version":"1.0","type":"link"}
