J4859D HPE Aruba 1G SFP LC LX 10km SMF Transceiver

The Aruba J4859D is a 1 Gigabit Small Form-factor Pluggable (SFP) transceiver module designed for long-distance network connections using single-mode fiber (SMF). It’s a versatile and critical component for extending network reach in a variety of environments, including data centers, enterprise campuses, and Internet Service Provider (ISP) links. The “LX” in its name signifies that it conforms to the 1000BASE-LX standard, which is designed for long-wavelength, single-mode fiber connections.

Here is a detailed description of the Aruba J4859D:

Key Features and Specifications:

• Form Factor: SFP (Small Form-factor Pluggable). This hot-pluggable design allows for easy installation and removal from switches, routers, and other networking devices without requiring a power down, which simplifies maintenance and upgrades.
• Speed: It supports a data transfer rate of 1 Gigabit (1000 Mbps). This provides ample bandwidth for high-speed data transmission, server connections, and core network aggregation.
• Standard: The module is compliant with the IEEE 802.3z 1000BASE-LX standard. This standard specifies the use of long-wavelength laser light over single-mode fiber.
• Fiber Media: The primary use case for the J4859D is with single-mode fiber (SMF), specifically 9/125 µm. This is what enables its long-distance capabilities. It can also operate over multimode fiber for shorter distances, though this is not its primary function.
• Distance:Single-mode fiber: The module can reliably transmit data over single-mode fiber for distances up to 10 kilometers (approximately 6.21 miles).
• Multimode fiber: It can also support connections over multimode fiber, with distances up to 550 meters, depending on the fiber type (OM2 or OM1).
• Wavelength: It operates at a wavelength of 1310 nm, which is the standard for 1000BASE-LX single-mode transceivers.
• Connector: It features a duplex LC connector for a standard, reliable dual-fiber connection.
• Digital Diagnostics Monitoring (DDM): The J4859D includes DDM functionality, also known as Digital Optical Monitoring (DOM).
