Transceivers type GLC-LH-SM-20 | 20km
We've been working with QT for about six months now, and I've placed three orders for fiber optic products like cables, DAC cables, and transceivers. They offered a great factory price with a bulk discount, which was a nice deal. I'm planning to order some nic cards next time.
