The JBX01496 100GBASE-ZR4 QSFP28 transceiver represents the pinnacle of long-reach optical networking technology, specifically designed for demanding enterprise and carrier applications. This high-capacity optical module enables seamless 100Gbps connectivity across distances up to 80 kilometers, making it an exceptional choice for geographically dispersed data centers, metropolitan interconnects, and regional network expansions. Technical Specifications & Performance: This transceiver operates on the 100GBASE-ZR4 standard, delivering four lanes of 25GB/s each over a single fiber strand using wavelength division multiplexing. The 9/125μm single-mode fiber specification ensures minimal signal degradation over extended distances. Equipped with Forward Error Correction (FEC), the module maintains signal integrity and reduces bit error rates, guaranteeing reliable data transmission across the full 80km reach. Connectivity & Compatibility: The Duplex LC/UPC fiber connectors provide industry-standard connectivity with excellent optical performance characteristics. The module is fully backward-compatible with Cisco QSFP-100G-ZR4-S systems, eliminating the need for expensive upgrades to existing network infrastructure. The compact QSFP28 form factor allows deployment in standard network switch line cards without modification. Reliability & Compliance: Manufactured with a robust metal case housing and precision laser transmitter, this transceiver withstands demanding network environments. Operating temperatures of 0-70°C (32-158°F) accommodate most data center conditions. The module holds Class 1 Laser certification, TUV, UL, and FDA compliance (21CFR 1040.10), ensuring safety in enterprise deployments. RoHS and ELV directive compliance (EU 2002/95/EC) supports sustainability initiatives and regulatory requirements across global markets. Application Scenarios: Ideal for: Data center campus interconnects, metropolitan area network (MAN) expansion, carrier-grade long-haul links, disaster recovery site connectivity, and multi-site enterprise networks. Network architects can confidently deploy this module for mission-critical applications requiring exceptional reach and reliability. Value Proposition: Free standard shipping on orders over $99, 90-day limited warranty coverage, and custom brand programming availability ensure maximum flexibility and value. The JBX01496 delivers enterprise-grade performance at competitive pricing, with qualified manufacturing standards (IEEE 802.3bm, QSFP28 MSA, SFF-8665) verified for integrity and performance assurance.
