Server power supply for telecom infrastructure

The Supersuperuncle PT7320-31-1W unit is built for rack-mounted telecom and data-centre equipment that require a hot-swap power source. It targets system integrators and network operators who need a field-replaceable module with a standard ESFP form factor.

Optical link budget and reach

The module transmits at 1310 nm over single-mode fibre with a 15 km reach and a 55 m minimum link distance. This wavelength and distance pairing suits campus or metro interconnects where the fibre plant is already deployed. The ESFP interface frees a standard SFP cage for other transceivers while the power supply occupies its own slot.

Thermal and power profile

Rated for continuous operation at 30 °C ambient, the supply draws 31 W typical and peaks at 7320 mW under full load. No external fan is required; the chassis airflow handles cooling. Acoustic output remains below the threshold for quiet server rooms.

Questions about this item

What power limit appears first when the PT7320-31-1W runs continuously?

The 55 M rating defines the sustained load ceiling before protection engages.

How much heat and noise does the unit produce during all-day operation?

The 15 km optical link runs cool, so fan speed stays low and acoustic output remains minimal.

Which server chassis and backplane must I already have for this supply to fit?

A 1310 nm single-mode receptacle and ESFP cage are required for the module to seat and power up.
