XFP transceivers have been standardized by multisource agreements

Another characteristic shared by this group of transceivers is that they’re OSI Layer 1 devices –they’re transparent to data and do not examine or alter data in any way. Although they’re primarily used with Ethernet, they’re also compatible with uncommon or legacy standards such as Fibre Channel, ATM, SONET, or Token Ring.Formats for SFP, SFP+, and XFP transceivers have been standardized by multisource agreements (MSAs) between manufacturers,10GBE XFP TO XFP COPPER CABLE 1M so physical dimensions, connectors, and signaling are consistent and interchangeable. Be aware though that some major manufacturers, notably Cisco, sell network devices with slots that lock out transceivers from other vendors.What we did first of all, was to take a 10G XFP LR with 1310nm generated by a DFB Laser. This took us to the above-mentioned 640metres!  The 1700 were achieved by using 10G XFP ER at 1550nm.In addition to all of this, we also used a mode conditioning cable when coupling the laser.Finally – after a long waiting time we now hold one of the first tunable DWDM XFP in our hands.
What a feeling… A 10G pluggable transceiver allowing reconfigurable wavelengths. Just imaginge, a) what advantages it brings you for your DWDM networks and b) the flexibility it allows for your stock keeping regarding emergency inventory. Since most hostsystems can’t control the wavelength tuning ability we’ve added a new beta feature to the flexBox software flexConnect: Finisar wavelength tunability Now you can persistently reconfigure the wavelangths, it even stays after unplugging/reboot/power off. Thus you can now easily build a lightsource that is adjustable over the whole C-Band. Beginning from 1528nm (196,15 THz) up to 1568nm (191,1THz). In other words: ITU channel C11 to C60 at 10Gigabit with 23dB (+/- 80km) power budget!
