The LumaOptics XFP-ZR XFP Transceiver exhibits excellent wavelength stability, Designed for 10G SDH/SONET, 10GBASE-ZR and 10G Fiber- Channel applications. The transceiver consists of two sections: The transmitter section incorporates a colded EML laser. And the receiver section consists of a APD photodiode integrated with a TIA. All modules satisfy class I laser safety requirements. The LumaOptics XFP transceiver provides an enhanced monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage.
