Description

The J4858D-BCC is a drop-in compatible replacement for the Aruba J4858D. This 1000BASE-SX SFP transceiver provides plug-and-play compatibility with Aruba switches and networking platforms that require 1.25Gbps Gigabit Ethernet connectivity over multi-mode fibre. - IEEE 802.3z 1000BASE-SX compliance guarantees interoperability with any standard Gigabit Ethernet SFP port - SFP form factor, 1.25Gbps data rate, 850nm wavelength, LC duplex connector - Up to 550m reach over 50/125µm OM2 multi-mode fibre, 275m over 62.5/125µm OM1 fibre - Digital optical monitoring (DOM) support via SFF-8472 enables real-time parameter tracking - Hot-swappable design with standard 0 to 70°C operating temperature range - MSA compliant for use across multi-vendor network environments

Features

• IEEE 802.3z 1000BASE-SX standard compliance ensures seamless interoperability with any vendor's Gigabit Ethernet SFP slot, including mixed-vendor deployments where the same module may be used across different switch platforms
• 850nm VCSEL laser transmitter operates within a 830-860nm spectral window with -9 to -3dBm average output power and 7.5dB minimum optical budget, sufficient for typical campus and data centre multi-mode installations
• Digital diagnostics monitoring via SFF-8472 two-wire serial interface provides real-time access to temperature, supply voltage, TX bias current, TX output power, and RX input power for proactive link management
• Reach scales with fibre grade: 550m over OM2 (50/125µm, 500 MHz·km), 275m over OM1 (62.5/125µm, 200 MHz·km), with higher-grade OM3/OM4 fibre extending usable distance beyond the rated 500m OM2 specification
• Hot-swappable SFP form factor with duplex LC connector enables in-service replacement without powering down the host switch, reducing maintenance windows in production networks
• Commercial temperature range (0 to 70°C) with single +3.3V supply and maximum 130mA current draw suits standard enterprise switch environments and rack-mounted installations
• SFP MSA (SFF-8477) compliance guarantees mechanical and electrical compatibility with all MSA-compliant SFP ports, including those in routers, switches, media converters, and NICs

FAQs

Q: Will this work in place of the Aruba J4858D?
A: Yes. The J4858D-BCC is a direct replacement for the Aruba J4858D. Both are IEEE 802.3z 1000BASE-SX compliant SFP transceivers operating at 850nm over multi-mode fibre at 1.25Gbps. The module is plug-and-play compatible with Aruba switches and will be recognised without configuration changes.

Q: Which Aruba switches support this transceiver?
A: This transceiver is compatible with Aruba switches that have SFP ports supporting 1000BASE-SX, including the 2530, 2540, 2615, 2620, 2930F, and 2930M series. It will work in any Aruba platform with a Gigabit SFP slot that accepts IEEE 802.3z modules. The module is MSA compliant and will also function in SFP ports from other vendors in multi-vendor environments.

Q: What fibre types and distances does this transceiver support?
A: This transceiver supports 50/125µm OM2 multi-mode fibre up to 550m, 62.5/125µm OM1 fibre up to 275m, and 62.5/125µm FDDI fibre up to 220m. On higher-grade OM3 or OM4 fibre, usable distance may extend beyond 550m due to the improved modal bandwidth of those fibre types, though 550m is the rated specification for OM2.

Q: How do I access DOM diagnostic parameters?
A: This transceiver implements SFF-8472 digital diagnostics monitoring. Parameters including temperature, supply voltage, TX bias current, TX output power, and RX input power are accessible via the two-wire serial interface at address A2h. Most Aruba switch operating systems expose these values through CLI commands or web interface, allowing real-time monitoring without external tools.

Q: Can this transceiver be used in a 10G SFP+ port at 1G speed?
A: Yes, provided the host switch supports dual-rate operation on its SFP+ ports. Many Aruba switches with SFP+ slots will auto-negotiate to 1Gbps when a 1000BASE-SX SFP is inserted. Consult the switch datasheet to confirm 1G/10G dual-rate support on the specific port, as not all SFP+ ports support backward compatibility to 1Gbps.
