Abstract	QTRx is an optical transceiver for particle physics experiments. The transmitters, each at 10 Gbps, are based on QLDD and 1x4 VCSEL array. The receivers, with data rates between 2.56 Gbps and 10 Gbps, are based on QTIA and 1x4 photodiode array, GaAs or InGaAs. QTRx is 20 mm × 10 mm × 5 mm and couples to an MT fiber connector. Preliminary tests indicate that QTRx meets design data rates with a power of 124 mW per Tx channel at 10 Gbps and 72 mW per Rx channel at 2.56 Gbps. More tests, including irradiation, will be carried out.
