Symmetric 10G-EPON ONU transceiver integrated with newly-developed burst-mode pre-bias timing control IC
We developed symmetric 10G-EPON ONU transceiver fully compliant with IEEE802.3av PR30. Output power of +5 dBm, sensitivity of -32.4 dBm, and fast LD turn-on/off time of 10 ns/7 ns were successfully achieved by newly-developed burst-mode pre-bias timing control IC.
Compact symmetric 10.3Gbps optical module for 10G-EPON ONU
We designed a compact symmetric 10.3Gbps optical module for 10G-EPON ONU with a sensitivity of −31.2dBm and a crosstalk of <0.1dB. Compact optical and mechanical design accomplishes a size of 14mm(L)×10.2mm(W)×6.8mm(H) to realize SFP+ transceiver.
Recent Advances in Telecommunications Avalanche Photodiodes
For high-bit-rate long-haul fiber optic communications, the avalanche photodiode (APD) is frequently the photodetector of choice owing to its internal gain, which provides a sensitivity margin relative to PIN photodiodes. APDs can achieve 5-10-dB better sensitivity than PINs, provided that the multiplication noise is low and the gain-bandwidth product is sufficiently high. In the past decade, the performance of APDs for optical fiber communication systems has improved as a result of improvements in materials and the development of advanced device structures. This paper presents a brief review of APD fundamentals and describes some of the significant advances
