This SFP28 transceivers P/N:GTS-B23B1-40DC are high performance,cost effective modules supporting data rate of 25.78Gbps and 40km transmission distance using a wavelength of 1270nm-TX/1330nm-RX via LC simplex connector.

The transceiver consists of three sections: a DFB laser transmitter, a PIN photodiode integrated with a trans-impedance amplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.

The transceivers are compatible with SFP28 Multi-Source Agreement and SFF-8472 digital diagnostic.




All Gigaopto’s transceivers are standards-based and MSA (Multi-Source Agreement) compliant, and rigorously tested and coded in our own facilities to ensure the highest level of performance. We conduct 100% application testing under end-use conditions.

For this GTS-B23B1-40DC, please refer to the P/N correspondence table. If you need more compatibility, please don’t hesitate to let us know.
