25 Gbps Multi-mode SFP Transceiver
AADONA DMM-25GSR is a high-performance and cost-effective small form factor pluggable SFP multimode transceiver module for 25G BASE SR Gigabit Ethernet per IEEE802.3ae and 25G Fibre Channel application.
This 25G SX multimode transceiver module fully complies with the SFP Multi-Sourcing Agreement (MSA) and can be used on MSA-compliant SFP ports of optical networking equipment. The transmitter section uses an 850nm VCSEL laser that is a class 1 laser product compliant according to International Safety Standard IEC 60825. The receiver section uses a high-speed PIN photodiode integrated with a trans-impedance preamplifier (TIA).
Additionally, the 25G SFP SX multimode transceiver family also provides an optional digital diagnostic interface per SFF-8472, which provides real-time monitoring of the transceiver temperature, supply voltage, laser bias current, laser average output power, and received optical power. These parameters are internally calibrated by default.
