The JBX01983 100BASE-LX10 SFP transceiver represents a reliable solution for organizations seeking extended-range optical connectivity at competitive pricing. This single-mode fiber module operates at 1310nm wavelength—the optimal wavelength for long-distance transmission—delivering consistent 100MB performance across distances reaching 15 kilometers. This extended range capability eliminates the need for expensive repeaters or amplifiers in campus and metropolitan deployments. Designed for direct compatibility with Extreme Networks infrastructure, the JBX01983 replaces the MGBIC-LC05 module while supporting legacy systems requiring OEM part numbers 10066 and 100FX-SFP-IR-OM. The duplex LC/UPC fiber connectors provide industry-standard connectivity with zero-insertion loss characteristics, ensuring signal integrity across your network backbone. Engineered with precision components including a laser transmitter housed in a metal case, this transceiver meets all critical performance benchmarks. It's qualified to IEEE 802.3u specifications and carries multiple safety certifications: Class 1 Laser designation, TUV validation, UL/FDA approval (21CFR 1040.10), and LN #50 7/2001 compliance. The 9/125 single-mode fiber core minimizes chromatic dispersion, enabling reliable long-distance transmission. Environmental compliance is built-in with RoHS/ELV directive adherence (EU directive 2002/95/EC), making this transceiver suitable for data centers and enterprises with strict sustainability requirements. The module operates reliably across 0-70°C temperature ranges, accommodating both indoor and outdoor cabinet installations. Manufactured in Vietnam and China to stringent quality standards, the JBX01983 includes a 90-day limited warranty. Custom brand programming is available for organizations requiring proprietary configurations. With free standard shipping on qualifying orders and reliable performance, this optical transceiver delivers exceptional value for enterprises modernizing network infrastructure or expanding existing Extreme Networks deployments.
