Note
1. TWDP figure requires the host board to be SFF-8431compliant. TWDP is calculated using the Matlab code provided in clause 68.6.6.2 of IEEE802.3ae.
2. 12dB reflection.
3. Conditions of stressed receiver tests per IEEE802.3ae. CSRS testing requires the host board to be SFF-8431 compliant.
4. Receiver overload specified in OMA and under the worst comprehensive stressed condition.

FAQ
1. What is CWDM transceiver?
A: A CWDM transceiver is a type of optical transceiver module used in fiber optic networks. 10G CWDM 10KM 1270nm Module is designed to transmit and receive multiple optical signals of different wavelengths simultaneously over a single optical fiber. CWDM transceivers typically use uncooled distributed feedback (DFB) laser diodes or Fabry-Perot (FP) lasers to transmit data at different wavelengths in the range of 1270nm to 1610nm.
2. Can I put an SFP module in a SFP+ port?
A: Usually SFP can be inserted into the SFP+ port, but the SFP+ optical module does not work in the SFP slot, and when the SFP module is inserted into the SFP+ port, the speed is 1G instead of 10G.The SFP module has a data transfer rate of up to 1.25Gbps, while the SFP+ module supports speeds up to 10Gbps or even higher. SFP+ modules have more advanced features and are designed for higher bandwidth and faster communication.However, some networking equipment supports both SFP and SFP+ slots called combo ports. These ports can accept either SFP or SFP+ modules, but you should consult the equipment's documentation to verify if it supports both.
