OET 1544
1GbE Ethernet Fiber Optic Transceiver (CWDM)
The OET 1544 is a compact CWDM compatible unmanaged Ethernet 3 port switch, designed to extend the reach of electrical Ethernet signals over long distances using a constant (fixed) high speed 1 Gbit/s fiber optic 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 1544 at the receiving end (using two fiber links) you have a cost-effective Ethernet extender system for distances up to 80km* – providing a stable, high speed 1Gbit/s error free optical connection between locations.
The OET 1544 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 10 Mbit/s, 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 the fiber SFP, When ordering please specify an SFP option in the wavelength required
