Akasa Intros AK-PCCE25-02 2.5GbE Adapter Capable of 25W PoE

Akasa has been into client networking products lately, with its recent low-profile 2.5 GbE adapter. The company's latest product in the category is the AK-PCCE25-02. This card provides 2.5 Gbps wired Ethernet connectivity, along with 25.5 Watts of Power-over-Ethernet (PoE), which should power equipment such as repeaters or cameras. It features all power switching components on board, and relies on a SATA power input for this purpose, and doesn't load the PCIe slot for PoE. Without the SATA power input, the PoE function is disabled, and it works like any other 2.5 GbE adapter. The card remains half-height, and a low-profile bracket is included. The company didn't reveal pricing.

That transformer puts out some serious PCI modem card vibes.

Maybe Akasa can make an AK-PCCE25-02-TPM (Transformer Poorly Made) variant for those people, so they can have some coil whine instead. Admittedly less inspiring but nothing software can't fix.

So which PoE standard it actually supports? There are a few, but by the 25.5W figure it looks like it's PoE+ (802.3at-2009). This is kind of important for a product like this, but even on their site it's not specified...

Why on earth would anyone want to connect a camera to a 2.5G port? And an AP connected to the PC directly is of questionable usefulness, except if the PC is acting as a router.
This might be useful for routers or switches with PoE-in, otherwise quite a niche use-case which could have been more simply solved by an injector.

Um.....security cameras. Uncompressed 1080p security cameras can eat upwards of 3Gbps of bandwidth per feed. Compressed 4k raw footage consumes 12-15GB per minute, a 2.5 Gbps connection tops out at 18.7GB per minute.

Except 2 of your twisted pairs are being used for power. Leaving 2 twisted pairs left for bandwidth, meaning you're getting like 100Mbit bandwidth.

Can you give me an example of a security camera that outputs uncompressed video? Even if someone has genuine need to use such a product, what's the use case of connecting it directly to a PC NIC and not to a proper mgig switch wih PoE+.

Probably not. Modern PoE standards (bt) use all 4 pairs for both data and power.

Are injectors universal? I can find only one that's advertised specifically for 2.5G - this one by Trendnet . At 50 € for 30 watts, it isn't cheap. For higher speeds, injectors don't even seem to exist.
