Знаю знаю эти модули. Недавно мы получили пробную партию таких.

Обнаружилось две крупные проблемы с ними. Мы отказали производителю.

Хотите выложу отчет?

There are some troubles with SFP WDM 3/20km SC.

First of all, many non-working modules: 2 out of 40.

There are 2 modules RMA!!! RMA(Return Merchandise Agreement) – bad ones

 

In this modules RX not work. I think that the number of non-working modules on a large quantity may be more, as we have received samples, which (in my opinion) is given more attention (to show the best performance in quality).

 

Second: there is problem with switches which has ports that are located closer to each other (such as D-Link DGS-3120-24SC). Photo below:

We think that problem in the construction of the body of the transceiver: spacers must be less in height. Photos are below:

 

Also patch cords with SC connectors are bad held in the SC socket of transceiver. If you pull the little patch cord - it falls out of the module.

 

Summary, we don’t like body of this transceivers.

Брак есть везде, нерабочие меняем (можем предварительно проверить).

Это новая партия, конструктивно изменены.

Вы уверены, в Вашем отчете я не вижу что это модули именно этого производителя?

Проблемы именно с этим корпусом.

Проверьте в коммутаторе у которого близко посажены порты.

Например Длинк.

Именно этого производителя нет, но так как производители осуществляют только сборку,

корпус именно этот. Просто выбросили недавно его на рынок.
