The Allied Telesis AT-SPSX-90 is an SFP-transceiver module for fibre optic applications in the Gigabit Ethernet range. It serves as a network transceiver for data transmission over multi-mode fibre (MMF) with a maximum data transfer rate of 1000 Mbit/s. The module is designed for use in switches, routers and other network devices that feature SFP interfaces. It enables the connection of network devices via optical fibre cables with a maximum reach of 550 metres at a wavelength of 850 nm. The connection is made via an LC optical cable connector, suitable for compact and secure connections in modern networks.

Applications

The module is designed for use in Gigabit Ethernet networks, particularly in environments where high data rates over medium distances are required. Typical application scenarios include connecting switches in data centres, office buildings or industrial networks, where stable and reliable fibre communication is essential. The support for multi-mode fibre makes it especially suitable for indoor and building cabling, where the 550-metre reach is sufficient.

Functions and features in detail

The AT-SPSX-90 features a Plug & Play function, enabling simple and quick integration into existing networks. The hot-swap capability allows the module to be replaced without interrupting network operation, which is beneficial for network maintenance and expansion. The housing is made of metal and is finished in silver, ensuring a robust and thermally efficient design. The RX sensitivity is -19 dB, indicating the module’s ability to correctly receive weak optical signals.

Technology explained simply

Data transmission occurs via fibre optics at a wavelength of 850 nm, typical for multi-mode fibre systems. The Tx power ranges from -8 dBmW (min) to -3 dBmW (max), describing the transmitter’s output power. The link budget of 11 dB indicates how much signal loss the system can tolerate without breaking the connection. This is crucial for planning network cabling to ensure signals remain sufficiently strong over the entire distance of up to 550 metres.

Compatibility and accessories

The module is compatible with SFP interfaces and can be used in devices that support this interface. It is designed for use with multi-mode fibre cables equipped with LC connectors.

Installation and mounting

Installation is performed by inserting the module into an SFP slot interface of a network device. Due to its Plug & Play feature, detection and configuration occur automatically. The hot-swap capability allows the module to be inserted or removed during operation without interrupting network traffic. Mounting requires no special tools or additional components.

Operational advantages

The module provides a reliable and high-performance connection via fibre optics with a reach of up to 550 metres. The hot-swap function and Plug & Play feature reduce downtime during maintenance. The robust metal housing construction and operating temperature range of -40 to 105 °C make the module suitable for demanding environments, such as industrial or outdoor applications. The LC connector ensures a secure and stable mechanical connection.

Operating conditions

The module is designed for operating temperatures from -40 to 105 °C, making it suitable for use in a wide range of environments, including industrial or outdoor installations. The high temperature resistance is particularly important in environments with significant temperature fluctuations or high ambient temperatures.
