Advanced Technologies for Single-mode Transceiver

QSFP-40GE-LR4 is a Cisco 40 Gigabit Single Mode QSFP+ transceiver that supports the 40 Gigabit Ethernet standard. It is designed for use in data center and enterprise networks, and is capable of transmitting data over single mode fiber optic cables at distances up to 10 kilometers. This transceiver supports advanced technologies such as:

  • Digital optical monitoring (DOM) which allows real-time monitoring of transceiver parameters such as temperature, voltage, and laser bias current.
  • Forward error correction (FEC) which helps to reduce the bit error rate and improve the signal quality in the transmission.
  • Low power consumption, this transceiver consumes less power than other comparable transceivers.
  • High temperature range for operation and storage, it can operate in temperatures up to 85°C and can be stored in temperatures up to 95°C
  • Compliance with RoHS and MSA standards, ensuring compatibility and interoperability with other devices in the network.
  • Built-in diagnostic monitoring functions (DDM) which enables real-time monitoring of the transceiver's internal parameters, such as temperature, voltage, and laser bias current, and allows the network administrator to quickly detect and troubleshoot any issues.

These advanced technologies allow this product to provide high-performance, reliable, and efficient data transfer in demanding network environments.

Resiliency and High Availability

QSFP-40GE-LR4 is a Cisco 40 Gigabit Single Mode QSFP+ transceiver that supports the 40 Gigabit Ethernet standard. It is designed for use in data center and enterprise networks, and is capable of transmitting data over single mode fiber optic cables at distances up to 10 kilometers. The transceiver is equipped with the necessary components to support resiliency and high availability in network environments. This includes features such as hot-swappability, which allows the transceiver to be replaced without disrupting network operations, and link aggregation, which allows multiple connections to be combined for increased bandwidth and redundancy. Additionally, the transceiver is built with a robust design and is tested to strict industry standards to ensure reliable operation in demanding network environments.

Robust Security and Dynamic Quality

The QSFP-40GE-LR4 Cisco 40 Gigabit Single Mode QSFP+ Transceiver is a robust and secure device that ensures high-quality data transmission.

In terms of security, the transceiver uses advanced encryption algorithms to protect against data breaches and unauthorized access. Additionally, it implements various security protocols to prevent unauthorized access to the network, such as Access Control Lists (ACLs) and Virtual Private Network (VPN) technology.

Dynamic Quality of Service (QoS) is another feature of this product that ensures high-quality data transmission. This feature allows the transceiver to automatically adjust the data rate and other parameters to optimize network performance and prevent congestion. This ensures that critical data, such as voice and video, receive priority over non-critical data, such as email and file transfers.

Moreover, the transceiver also has built-in monitoring and diagnostic capabilities that enable network administrators to quickly identify and troubleshoot any issues that may arise, helping to ensure optimal network performance and uptime.

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.

We guarantee our customers high quality and reliability for all our transceiver networking solutions, irrespective of the type and size of your network.
