Binardat 19 Port Gigabit POE Switch, 16 Ports POE+ 1000Mbps, 2 Gigabit Uplink, 1 Gigabit SFP, IEEE802.3af/at, 300W Internal Power Supply, Metal Case Unmanaged Plug and Play

5ポートのものから8ポート+SFP+のものに変えて、将来上流が10GbEになったりすることも見越して変えました。金属筐体で放熱性も良さそうです。 今のところ問題なく動いています。速度も2.5GbEで問題ありません DCの給電口が裏にあるので片側だけに配線をまとめられないのは少し残念ですが、 価格の割にいいものだと思います。

There weren't any reviews for this particular switch, so here you go. This switch is for those that need to convert a couple SFP+ 10G connections to a small number 2.5G or 1G RG45 connections, and are okay with an unmanaged switch. It's a good way to start experimenting with speeds beyond 1Gbps without spending too much. Construction is all metal, and it will take a few minor bumps without issue. It comes with a wall-wart style power supply for North American outlets, four rubber feet one can stick on, and an unhelpful quick start guide. This is an unmanaged switch so don't expect anything fancy. It does do what it is supposed to for a reasonably price (as far as these devices go). For my purposes, it's a win. I tested all the ports using iperf3 and they performed as expected. Testing from 2.5G to 2.5G (or to SFP-10G) I saw rates between 2.3 and 2.4Gbps; and going from SFP+ to SFP+, I saw rates around 9.4Gbps. Diving deeper....the switch passes VLAN tags just fine, even though it doesn't understand them. For SFP/SFP+ compatibility, I tried a generic 10G DAC cable, a generic SFP-10G-SR transceiver (coded as Intel), a generic SFP-10G-LR (coded as OEM), and a QSFPTEK SFP-1G RJ45 transceiver. All worked just fine. It supports both 1G SFP and 10G SFP+, and has an LED indicating which is detected. It has a small switch on the front labeled "Default or VLAN". This doesn't have anything to do with 802.1Q VLANs, this is a port isolation switch to prevent traffic between 2.5G ports. I did not test it, and most people will want to leave it at the default position. If this fits your needs, it's worth consideration. I'm happy with it so far.

très bon pour avoir du 2.5GB et transférer des données en réseau, N.B. Il faut que la carte réseau de ton ordinateur fonctionne a une vitesse de plus que 1GB sinon pas utile pour vous.

GEILER 10GBPS switch! - 3440x1440 lokales RDP (!!!) ... KEIN PROBLEM.

Pur non essendo un brand tra i più blasonati, sono rimasto piacevolmente colpito dalla qualità costruttiva e dalla robustezza di questo switch (non gestito) da 5 porte 2.5Gb Installazione immadiata e senza problemi, le porte rj45 - indipendenti e bidirezionali - si preoccupano di gestire e distribuire il flusso dati in ingresso sulle porte attive che ne fanno richiesta fino ad un massimo di 2.5Gb. Compatibile con le altre velocità classiche basate su rj45 quali 100T, 1000T. Non proprio economico ma comunque in linea (verso il basso) con modelli analoghi di altri brand. Rispetto a quelli (giustamente) più blasonati non perde il confronto e funziona molto bene. Rapporto qualità/presso molto buono, se siete alla ricerca di uno switch da 2.5Gb lo consiglio senza riserve.
