By the end of this article, you will have a comprehensive understanding of what the Aruba JL749A 10GB SFP+ LC LR 10km SMF is and how it can benefit your network infrastructure.

Understanding the Name

Let's begin by dissecting the name of this networking component:

  • Aruba: Aruba is a well-known brand in the networking industry. They produce a wide range of networking equipment, including switches, routers, and transceivers like the JL749A.
  • JL749A: The JL749A is a specific model or part number assigned by Aruba to this particular 10GB SFP+ LC LR 10km SMF transceiver. This alphanumeric code is used for identification and reference purposes.
  • 10GB: This part of the name indicates the data transfer rate supported by the transceiver. In this case, it can handle data at a speed of 10 gigabits per second (Gbps). This is a high-speed connection suitable for various networking applications, including data centers and enterprise networks.
  • SFP+: SFP+ stands for Small Form-Factor Pluggable Plus. It is a type of optical transceiver module used in networking equipment. SFP+ modules are hot-swappable, meaning they can be replaced or removed while the network is running, without disrupting the overall network operation.
  • LC: LC refers to the type of optical connector used on this transceiver. LC connectors are common in networking because of their small size and low insertion loss, making them suitable for high-speed data transmission.
  • LR: LR stands for Long Range. It signifies that this transceiver is designed for long-distance data transmission, which can be up to 10 kilometers (km) in this case. LR transceivers are ideal for connecting devices that are farther apart, such as buildings in a campus network.
  • 10km SMF: This part of the name specifies the supported distance and the type of optical fiber that can be used. SMF stands for Single-Mode Fiber, which is a type of optical fiber designed for long-distance transmission. The "10km" indicates that this transceiver is optimized for connections up to 10 kilometers.

Now that we've broken down the name, let's delve deeper into the technical aspects and practical applications of the Aruba JL749A 10GB SFP+ LC LR 10km SMF.

Technical Specifications

To fully understand the capabilities of the Aruba JL749A 10GB SFP+ LC LR 10km SMF, it's essential to examine its technical specifications. These specifications provide valuable information about its performance, compatibility, and usage scenarios. Here are the key technical details:

  • Data Rate: The transceiver supports a data rate of 10 gigabits per second (10Gbps). This high-speed capability makes it suitable for demanding networking applications that require fast data transmission.
  • Form Factor: The transceiver follows the SFP+ (Small Form-Factor Pluggable Plus) standard. This form factor is widely adopted in the industry, ensuring compatibility with a range of networking devices, including switches and routers.
  • Connector Type: The Aruba JL749A features LC connectors. LC connectors are known for their precision and low insertion loss, making them suitable for high-speed optical connections.
  • Transmission Range: The "LR" in the name indicates that this transceiver is designed for long-range applications. It can transmit data over distances of up to 10 kilometers (10km). This extended range is crucial for connecting devices in large networks or across expansive areas.
  • Fiber Type: The transceiver is optimized for Single-Mode Fiber (SMF). Single-Mode Fiber is ideal for long-distance communication due to its ability to transmit light signals over greater distances without significant signal loss.
  • Wavelength: The specific wavelength(s) used by this transceiver may vary depending on the manufacturer's design. Wavelengths are important as they determine the color of light used for transmission, and they should match the network's requirements and other connected components.
  • Compatibility: Compatibility is a vital aspect of any networking component. The Aruba JL749A is likely compatible with a range of Aruba networking equipment, including switches and routers. However, it's essential to check the compatibility list provided by the manufacturer to ensure seamless integration into your network.
