The JBX02354 25GBASE-SR SFP28 transceiver module represents a cost-effective solution for organizations upgrading to 25GB network speeds without requiring extensive infrastructure replacement. This dual-fiber multimode transceiver operates at 850nm wavelength, the industry standard for short-reach, high-speed optical communication. With support for 100-meter transmission distances over OM4 multimode fiber, it accommodates most campus and data center interconnection requirements. Key Technical Specifications: This SFP28 form-factor module delivers 25 gigabits per second data rates while maintaining full compatibility with Dell networking equipment, specifically replacing part numbers 407-AFGH, 407-BCIM, 019-078-056, 407-BCKZ, 407-BCHI, and 407-BCBK. The duplex LC/UPC fiber connection allows for simultaneous bidirectional transmission, critical for full-duplex network operations. Operating temperature range from -10°C to 85°C ensures reliable performance in controlled data center environments and field deployments. Compliance and Safety: The transceiver meets rigorous international standards including IEEE 802.3by, SFF-8402, and SFF-8472 specifications. It carries comprehensive safety certifications including Class 1 Laser, TUV, UL, and FDA compliance under 21CFR 1040.10. The module adheres to RoHS and ELV directives, ensuring environmentally responsible manufacturing and disposal. Applications and Use Cases: Ideal for data center network upgrades, campus backbone connectivity, and storage area network (SAN) implementations. This module excels in environments where organizations require increased bandwidth without migrating to single-mode fiber infrastructure. The 100-meter reach over OM4 fiber suits most internal data center and multi-building campus network scenarios. Warranty and Support: Includes a 90-day limited warranty covering hardware defects. Custom brand programming is available for organizations requiring vendor-specific firmware or configuration.
