Description
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 1×10^-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.
