Aruba / J4859D / Single mode 1G SFP LC LX 10KM SMF XCVR

The Aruba J4859D is a premium Gigabit Ethernet SFP optical transceiver specifically engineered for long-range connectivity over single-mode fiber networks, delivering reliable 1000BASE-LX/LH performance for enterprise campus networks, data centers, and metropolitan area networks requiring extended transmission distances. This professional-grade small form-factor pluggable module features a 1310nm wavelength FP laser transmitter capable of reaching 10 kilometers over standard 9/125µm single-mode fiber with LC duplex connectors. Furthermore, the Aruba J4859D incorporates digital diagnostic monitoring (DDM) capabilities compliant with SFF-8472 standards, providing real-time visibility into optical power levels, temperature, voltage, and laser bias current for proactive network monitoring and troubleshooting. Manufactured to meet strict Aruba and HPE specifications, this hot-pluggable transceiver operates at data rates up to 1.25 Gbps supporting Gigabit Ethernet (1000BASE-LX) and 1G Fibre Channel applications. The high-quality FP laser operating at 1310nm nominal wavelength paired with a PIN photodiode receiver delivers a minimum optical budget of 15dB, ensuring reliable transmission even over challenging fiber installations with multiple connectors and splices. Additionally, the Aruba J4859D features compatibility with a wide range of Aruba switch platforms including 2530, 2920, 2930F, 2930M, 3810M, and 6300 series switches, making it an essential component for building scalable network infrastructure. The compact form factor measuring just 5.6×1.5×1.3cm and weighing only 20 grams enables high-density port configurations in space-constrained rack environments. The transceiver operates on a single +3.3V power supply with low power consumption characteristics, generating minimal heat even during sustained high-throughput operation. Consequently, network administrators can deploy fiber backbone connections between buildings, connect remote wiring closets to core switches, or establish long-distance uplinks between data center floors with complete confidence in performance and reliability. The module complies with IEEE 802.3z Gigabit Ethernet standards, SFP Multi-Source Agreement (MSA) specifications SFF-8477, and meets laser safety requirements under IEC 60825-1 Class 1 certification. The operating temperature range of 0-70°C accommodates standard networking environments while the hot-swappable design enables installation and replacement without powering down network equipment. Whether you’re upgrading legacy copper infrastructure to fiber, extending network reach beyond 100-meter copper limitations, or deploying new campus fiber backbones, this Aruba J4859D delivers enterprise-grade performance with guaranteed compatibility across Aruba networking platforms. The transceiver can also support 550-meter transmission over multimode fiber (50/125µm or 62.5/125µm) when used with appropriate mode conditioning patch cables, providing additional deployment flexibility.
