Aruba J4858D 1G SFP LC SX 500m OM2 MMF Transceiver

The Aruba J4858D, for instance, is a 1 Gigabit Small Form-factor Pluggable (SFP) transceiver module designed for use with multimode fiber (MMF). Essentially, it is a key component for providing high-speed fiber-optic connections over relatively short distances within data centers, enterprise networks, and other campus environments.

Consequently, here is a detailed description of the Aruba J4858D:

Key Features and Specifications:

• Form Factor: SFP (Small Form-factor Pluggable). This compact, hot-pluggable design, for one thing, allows for easy installation and removal without interrupting network operations, and as a result, it enables high port density on switches
• Speed: It provides a data transfer rate of 1 Gigabit (1000 Mbps), which is to say, it is suitable for high-bandwidth applications like server connectivity, core network aggregation, and demanding data transfers.
• Standard: The module is compliant with the IEEE 802.3z 1000BASE-SX standard. This standard, in particular, specifies the use of short-wavelength laser light over multimode fiber.
• Fiber Media: It is designed for use with multimode fiber (MMF). Furthermore, the maximum transmission distance depends on the type of multimode fiber used:
  • Up to 550 meters (approximately 1804 feet) on 50/125 µm multimode fiber with 500 MHz*km modal bandwidth (OM2).
  • Up to 220 meters on 62.5/125 µm multimode fiber with 200 MHz*km modal bandwidth (OM1).
• Wavelength: It operates at a wavelength of 850 nm, which is characteristic of 1000BASE-SX transceivers for multimode fiber.
• Connector: It features a duplex LC connector, which provides a reliable, dual-fiber connection.
• The J4858D often includes DDM functionality, also known as Digital Optical Monitoring (DOM). allows network administrators to monitor key operational parameters in real-time, such as optical transmit and receive power, temperature, and voltage, which is invaluable for troubleshooting and proactive network management.
• including the 2530, 2920, and 2930F series, as well as other compliant networking equipment that supports SFP modules.
