Manually force 10Mbit electrical speed (if needed)
Fiber transceiver speed always 1 Gbit
Auto or manual electrical crossover selection
Distances up to 40km (24.8 miles) over fiber
18 CWDM wavelength selections (ITU-T G.694.2)
The OET 1540 is a compact CWDM compatible Ethernet 3 port switch, designed to extend the reach of electrical Ethernet signals over long distances using a constant (fixed) high speed 1 Gbit optical transceiver speed.
18 selectable CWDM wavelengths are provided to enable the module to be used in a multiplexed CWDM environment. When paired with another OET 1540 at the receiving end (using two fiber links) you have a cost effective Ethernet extender system for distances up to 40km – providing a stable, high speed 1Gbit error free optical connection between locations.
The OET 1540 has two standard RJ45 electrical Ethernet ports plus fiber I/O and functions as a 3 port Ethernet switch. For legacy system use; each electrical Ethernet port can be set for automatic speed detection (10/100/1000) or forced to 10Mbit, and each port can use auto crossover detection or be forced manually if needed. These functions are available using the dip switch.
Note. The module does not include a fiber SFP sub module, one must be specified from the options list
