Data Rate and Transmission Distance
The 845397-001 HPE SFP28 Transceiver Module is designed to support data rates of up to 25 Gigabits per second (Gbps) over a variety of distances. The module operates at a wavelength of 850 nanometers (nm) and supports short reach (SR) transmissions over multi-mode fiber (MMF) cabling.
The transmission distance for the HPE SFP28 Transceiver Module depends on the type of MMF used. The module supports OM3 and OM4 fiber types, which have maximum transmission distances of 300 meters and 400 meters, respectively, at 25 Gbps. This makes the HPE SFP28 Transceiver Module ideal for use in data center and enterprise networks where high-speed connectivity over short distances is required.
In addition, the module supports backward compatibility with 10 Gigabit Ethernet (10GbE) networks, which means that it can be used to upgrade existing networks to higher speeds without the need for costly cabling upgrades. The module supports 10GbE transmissions over a maximum distance of 400 meters on OM3 fiber and 550 meters on OM4 fiber.
It is important to note that the actual transmission distance of the HPE SFP28 Transceiver Module may be affected by a variety of factors, including the quality of the cabling, the environmental conditions, and the presence of electromagnetic interference (EMI). Therefore, it is recommended to follow the manufacturer's guidelines for cabling and installation to ensure optimal performance and reliability.
The data rate and transmission distance capabilities of the 845397-001 HPE SFP28 Transceiver Module make it a powerful and flexible solution for high-speed network connectivity over short distances in data center and enterprise environments.
Optical Specifications of the Transceiver Module
The 845397-001 HPE SFP28 Transceiver Module is an optical module designed to provide high-speed connectivity over short distances using multi-mode fiber (MMF) cabling. The module operates at a wavelength of 850 nanometers (nm), which is the standard wavelength for short-reach (SR) optical transmission.
The optical specifications of the module include the following:
- Transmit Power: The HPE SFP28 Transceiver Module has a minimum transmit power of -7.6 dBm and a maximum transmit power of -1.0 dBm.
- Receive Sensitivity: The module has a receive sensitivity of -11.5 dBm, which means it can detect weak optical signals and convert them into digital data.
- Receiver Overload: The receiver overload level of the module is 0.5 dBm, which is the maximum input power that the receiver can handle without causing damage.
- Extinction Ratio: The extinction ratio is a measure of the modulation depth of the optical signal, and the HPE SFP28 Transceiver Module has an extinction ratio of at least 3 dB.
- Bit Error Rate (BER): The module has a BER of less than 1x10^-12, which means it is highly reliable and can maintain data integrity over long periods of time.
- Optical Connector: The module is equipped with a standard LC optical connector, which is compatible with most MMF cabling types.
It is important to note that the optical specifications of the HPE SFP28 Transceiver Module may be affected by a variety of factors, including the quality of the cabling, the environmental conditions, and the presence of electromagnetic interference (EMI). Therefore, it is recommended to follow the manufacturer's guidelines for cabling and installation to ensure optimal performance and reliability.
Supported Fiber Types and Connector Types
The 845397-001 HPE SFP28 Transceiver Module is designed to support multi-mode fiber (MMF) cabling with a core diameter of 50 or 62.5 microns. MMF is a type of optical fiber that is optimized for short-reach transmission applications, typically ranging from a few hundred meters to a few kilometers.
The module is equipped with a standard LC optical connector, which is a small form-factor connector that is commonly used in optical networking applications. The LC connector features a 1.25 mm ferrule, which is the part of the connector that holds the optical fiber in place.
In addition to supporting the LC connector, the HPE SFP28 Transceiver Module also complies with the Small Form-factor Pluggable 28 (SFP28) industry standard, which is a compact, hot-pluggable optical transceiver module designed for use in high-speed data communication applications.
The use of standardized fiber types and connector types enables easy interoperability between different vendors' equipment and reduces the likelihood of compatibility issues. It also simplifies the installation and maintenance of optical networks, as technicians can use standardized tools and procedures to connect and test optical links.
It is important to note that the performance of the HPE SFP28 Transceiver Module may be affected by the quality and characteristics of the MMF cabling used, such as the modal bandwidth, the attenuation, and the dispersion. Therefore, it is recommended to use high-quality, certified MMF cabling and follow the manufacturer's guidelines for cabling and installation to ensure optimal performance and reliability.

About Refurbished Products
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.
