4810, Juniper QFX, Extreme X670, Alcatel Omniswitch 6900, Cisco Nexus 3000, etc.). These ports enable data rates of up to 40 Gigabit/s with the appropriate QSFP+ transceivers. However, what has been lacking until now has been the transmission distance.  Currently, using the multimode QSFPs+ available , distances of up to150m (and that is just about it!) can be achieved on OM4 fiber.

We successfully tested one of the first available QSFP+ LR Transceivers. The transceivers have an integrated MUX/Demux which transmit 1270, 1290, 1310 and 1330nm CWDM wavelengths for up to 10km
