Baudcom CWDM XFP Transceiver exhibits excellent wavelength stability, supporting operation at 100 GHz channel, cost effective module. It is designed for 10G CWDM SDH, 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. Baudcom CWDM 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.

Q&A
Question1: Is SFP module compatible with Zyxel, 3Com, Cisco and Huawei?
Answer: No, SFP module is compatible with Zyxel, 3Com and Cisco. For Huawei, it can only be compatible with the old models, because some new devices (such as S6800 series) requires special compatibility code.
