The JBX02211 1000BASE-BX SFP transceiver is a premium optical networking solution engineered for extended-reach gigabit applications. Specifically designed as a Cisco GLC-BX-U60 compatible replacement, this module enables transmission over 60 kilometers of singlemode fiber—exceeding standard IEEE 802.3ah specifications for bidirectional communication. Key Technical Specifications: This transceiver operates at 1Gbps data rates using 9/125 micron singlemode fiber with simplex LC/UPC connectors. The metal case housing protects the precision laser transmitter, while SFF-8472 qualification ensures interoperability with enterprise switching equipment. Operating temperature range of 0-70°C accommodates both climate-controlled data centers and outdoor network cabinets. Compliance & Safety: Full RoHS/ELV compliance meets EU Directive 2002/95/EC environmental standards. Class 1 laser certification (LN #50 7/2001) with TUV, UL, and FDA 21CFR 1040.10 approvals provides comprehensive safety documentation for enterprise procurement requirements. Applications & Use Cases: Ideal for telecommunications infrastructure, long-haul network backbone extensions, metropolitan area networks (MANs), and carrier-class deployments. Particularly valuable for organizations requiring reliable, maintenance-free long-distance connections without expensive optical amplification infrastructure. Compatibility & Installation: Drop-in compatible with Cisco switches, routers, and network equipment supporting SFP modules. Custom brand programming is available for OEM integration. Ships from US locations (Danville, CA or Beaufort, SC) with free standard shipping on orders exceeding $99. Warranty & Support: 90-day limited warranty provides peace of mind for critical infrastructure deployments. Backed by international manufacturing standards (Vietnam/China), this represents enterprise-grade reliability at competitive pricing.
