LC Connector Type and Advantages

LC (Lucent Connector) is a small form factor (SFF) fiber optic connector type that is commonly used in high-speed data communication applications. The 845398-B21 HPE 25GB SFP28 100m LC Multimode Fiber Transceiver Module uses the LC connector type for transmitting and receiving optical signals between the transceiver module and the fiber optic cable.

The LC connector type is smaller than other connector types, such as SC and ST, and is designed for high-density applications. Its small size allows for more ports to be fitted onto a single device or panel, which makes it a popular choice for use in data centers and other environments where space is limited. Additionally, the LC connector type is easy to install and maintain, and its snap-in design ensures a secure connection.

The LC connector type is also known for its low insertion loss and high return loss, which helps to minimize signal attenuation and maximize signal strength. This makes it ideal for use in high-speed data communication applications, where signal quality is critical. Furthermore, the LC connector type is compatible with both singlemode and multimode fiber optic cables, which makes it a versatile connector type that can be used in a wide range of applications.

The LC connector type used in the 845398-B21 HPE 25GB SFP28 100m LC Multimode Fiber Transceiver Module offers several advantages, including its small size, high-density capabilities, easy installation and maintenance, low insertion loss and high return loss, and compatibility with both singlemode and multimode fiber optic cables. These advantages make it a popular choice for use in high-speed data communication applications, particularly in data centers and other environments where space is limited.

Connecting the Transceiver Module to Fiber Optic Cables

The 845398-B21 HPE 25GB SFP28 100m LC Multimode Fiber Transceiver Module is designed to transmit and receive optical signals over fiber optic cables using the LC connector type. Connecting the transceiver module to the fiber optic cables involves several steps:

  • Ensure that the fiber optic cables are properly terminated with LC connectors on both ends. The LC connectors should be inspected for any signs of damage or contamination, such as scratches, cracks, or dust.
  • Remove the protective caps from the LC connectors on both ends of the fiber optic cables.
  • Insert the LC connectors on the fiber optic cables into the LC receptacles on the transceiver module. The LC connectors should be inserted straight into the receptacles until they click into place.
  • Secure the LC connectors in place by tightening the screws on the transceiver module. This will ensure a stable and reliable connection between the transceiver module and the fiber optic cables.
  • Verify that the transceiver module is properly installed and functioning by checking the status lights on the device. The status lights will indicate whether the transceiver module is receiving and transmitting optical signals over the fiber optic cables.

It is important to note that the 845398-B21 HPE transceiver module is designed to work with multimode fiber optic cables that support a distance of up to 100 meters. It is recommended to use only HPE-approved fiber optic cables to ensure compatibility and optimal performance. Additionally, it is important to follow proper handling and installation procedures when working with fiber optic cables, as they are sensitive to damage from bending, twisting, and other mechanical stresses.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Building a fibre-optic network calls for a lot of planning and consideration of many factors. Transceivers are part of the many devices used to build optical fibre systems. A transceiver serves the combined roles of a transmitter and a receiver in that it transmits and receives signals. They are most common in communication equipment such as cellular phones, cordless telephone sets, and radios. Small form factors are required as networks become dense and space is limited, which sees transceivers included in chipsets.

In local area networks (LAN), a transceiver is used to connect a computer to printers and other devices on the network. Usually, the transceiver is integrated into the Network Interface Card (NIC)

Typical Roles of a Transceiver

  • Used to convert frequencies from IF to RF.
  • Widespread use in wireless communication to transmit data – voice, data, and video.
  • RF transceivers are used in communication devices to support radio and TV signal transmission, digital signals transmission, and satellite communication.
  • Collision detection – detection of simultaneous signals on the network.
  • Transceivers can be deployed to provide a jabber function to interrupt the transmission of long data stream outputs.

Look no further for all types of transceivers including fibre optic transceivers, wireless transceivers, Ethernet transceivers, and RF transceivers. All these transceivers have different characteristics and support full-duplex communication, but the principle behind their work remains the same. Different types of transceivers will have varying numbers of ports used in the transceiver networking connections.

RF Transceivers: these devices are used to transmit video or voice data over a wireless medium. Commonly used for satellite communication, radio transmission, and ITE/WiMax/WLAN networks. The radio transceiver works by silencing the receiver when it is transmitting. There is an electronic switch that facilitates the connection of both the receiver and transmitter on the same antenna. The switch protects the receiver from damage that may be caused by the transmitter output.

Fiber Optic Transceivers: Also referred to as optical modules or fibre optical transceivers. Used to transmit data in fibre optic technology. The network must also have electronic components to encode or decode data into light signals.

Ethernet Transceivers: Basically used to connect electronic devices in a network so that they are able to transmit and receive data. It is also referred to as a media access unit (MAU). The best application of these transceivers is in the specification of IEEE 802.3 and Ethernet. Ethernet transceivers will detect a collision, provide Ethernet interface processing, convert digital data, and provide access to the network.

Wireless Transceivers: Wireless transceivers are a fundamental component necessary for data delivery in wireless networks. These transceivers have two layers. The physical layer has a baseband processor and RF front end. The processor converts a bitstream to a collection symbol flow for data transmission. The second layer is a MAC layer for link traffic control in contacting wireless links, improving data throughput, and preventing collisions.
