Hi,
There is a company in Taiwan called Yuan Dean Scientific. They have a range of suitable products - incl. an RJ-45 with built-in LEDS and Magnetics. I have used their product. However, I do not know if they have a version with LEDs & WITHOUT magnetics. Maybe you can try. The contact person is :
Wendy Wang (ydstech@ms11.hinet.net)
Yuan Dean Scientific Co., Ltd.
Tel#886-6-2052212
Fax#:886-6-2052088
They will be able to supply samples in a week or so.
I hope this is useful !!
