Role and fit

The Transition Networks SPOEB1011-105-NA is a stand-alone Fast Ethernet PoE media converter designed for enterprise networks. It bridges 10/100 Mbps copper links to fiber while delivering 48V DC power to compatible powered devices over existing CAT5 cabling. Network engineers use it to extend powered connections beyond standard Ethernet distance limits without adding local power outlets.

Sustained operation

The unit draws up to 20 Watts from an external supply that accepts 90 to 250V AC input and provides regulated 48V DC output. Built-in over-current protection, under-current detection and fault protection input monitor the powered device continuously. If fiber receive signal is lost, the PSE/LPT switch can cut UTP port power for two seconds to trigger a remote device reset, maintaining link stability over long runs.

Installation notes

The compact enclosure measures 1.00 by 3.25 by 4.80 inches and ships with the external power supply included. Setup requires only connecting fiber, copper and AC mains; no software configuration is needed for basic IEEE 802.3af operation. The feature-enhanced firmware allows enabling or disabling functions and forcing port capabilities, but advanced options need manual study. It does not suit networks that require Gigabit speeds or IEEE 802.3at high-power PoE.

Questions about this item

How much power does the SPOEB1011-105-NA draw when it is running continuously?

The unit consumes a maximum of 20 Watts from its external 48V DC supply, which accepts 90 to 250V AC input.

What cabling and powered device must I already have for this converter to work?

You need a fibre link on one side, a CAT5 copper run on the other, and an IEEE 802.3af compliant powered device such as a VoIP phone or wireless access point.

Will the SPOEB1011-105-NA interoperate with older 10 Mbps Ethernet equipment I still use?

Yes, the converter negotiates 10 or 100 Mbps on the copper port, so legacy 10BASE-T devices connect without configuration changes.
