25-Gb/s 100-m MMF Transmission Using a Prototype 1.3-

A prototype transceiver composed of a 1.3-μm-range lens-integrated laser diode and photodiode as well as a complementary metal-oxide-semiconductor (CMOS) laser diode driver and a CMOS transimpedance amplifier for high-speed optical interconnections was developed. It demonstrated 25-Gb/s error-free 100-m multimode fiber transmission, with power dissipation of only 9 mW/Gb/s, for the first time.

A 25-Gb/s × 4-ch optical transceiver module was developed. To obtain a compact module, CMOS analog front-end ICs, a lens integrated connector, and small LGA package was applied. The module demonstrated 25-Gb/s error-free transmission.

-Range CMOS-Based Transceiver for Optical Interconnections

A 25 Gb/s × 4-ch, 8 × 8 mm2 optical transceiver module for optical interconnection has been developed. To obtain a compact optical module suitable for chip-to-chip interconnection, a lens integrated connector, a small low temperature co-fired ceramic (LTCC) package, and a precise lens assembling technology were used. Experimental results showed that the proposed module can achieve 25 Gb/s error free transmission.
