Transceiver optik 40 Gbit/s menggunakan modul OTDM MUX novel telah dibangunkan. Modul MUX OTDM (Optical-Time-Division-Multiplexing), komponen teras pemancar, terdiri daripada pembahagi optik, dua modulator penyerapan elektro (EA) dan penggabung dalam bungkusan kecil yang dimeterai. Memandangkan laluan optik berpecah berjalan melalui "udara" dalam modul, hubungan fasa optik yang sangat stabil antara denyutan berjalin bit dapat dikekalkan. Dengan modul OTDM MUX, pemilihan antara format Return-to-Zero (RZ) konvensional dan format RZ (CS-RZ) yang ditindas pembawa dilakukan dengan mengubah sedikit panjang gelombang laser-diod. Dalam penerima, kereta api data optik 40 Gbit/s dinyahmultipleks secara optik kepada kereta api optik 10 Gbit/s, sebelum dikesan oleh penerima O/E untuk format RZ 10 Gbit/s. Penilaian MUX-DEMUX berturut-turut bagi transceiver menunjukkan sensitiviti yang baik di bawah -30 dBm diukur pada input optik 40 Gbit/s untuk mencapai kadar ralat bit (BER) 10-9. Satu lagi ciri unik sistem transceiver ialah keupayaan suis spektrum. Operasi pemultipleksan RZ dan CS-RZ yang stabil telah disahkan dalam eksperimen. Sebaik sahaja kami melaraskan isyarat optik 40 Gbit/s kepada format CS-RZ, spektrum optik akan mengekalkan bentuk spektrum CSnya untuk masa yang lama untuk memanfaatkan ciri penghantaran panjang yang stabil. Dalam eksperimen gelung kitaran semula yang menggunakan transceiver OTDM MUX, margin kuasa yang lebih besar telah berjaya diperhatikan dengan format CS-RZ berbanding dengan format RZ konvensional, menunjukkan bahawa pengekodan yang betul bagi RZ konvensional dan CS-RZ telah direalisasikan dengan transceiver prototaip ini. Dalam kes format CS-RZ, ralat bebas (BER < 10-9) transmisi melebihi 720 km telah dicapai dengan jarak penguat pengulang yang panjang 120 km.

Abstract: 40 Gbit/s optical transceiver using a novel OTDM MUX module has been developed. OTDM (Optical-Time-Division-Multiplexing) MUX module, the core component of the transmitter, consisted of a optical splitter, two electro-absorption (EA) modulators and a combiner in a sealed small package. As the split optical paths run through the "air" in the module, greatly stable optical phase relation between bit-interleaved pulses could be maintained. With the OTDM MUX module, the selection between conventional Return-to-Zero (conventional-RZ) format and carrier-suppressed RZ (CS-RZ) format is performed by slightly changing the wavelength of laser-diode. In a receiver, 40 Gbit/s optical data train is optically demultiplexed to 10 Gbit/s optical train, before detected by the O/E receiver for 10 Gbit/s RZ format. Back-to-back MUX-DEMUX evaluations of the transceiver exhibited good sensitivities of under -30 dBm measured at 40 Gbit/s optical input to achieve the bit-error-rate (BER) of 10-9. Another unique feature of the transceiver system was a spectrum switch capability. The stable RZ and CS-RZ multiplexing operation was confirmed in the experiment. Once we adjust the 40 Gbit/s optical signal to CS-RZ format, the optical spectrum would maintain its CS spectrum shape for a long time to the benefit of the stable long transmission characteristics. In the recirculating loop experiment employing the OTDM MUX transceiver, the larger power margin was successfully observed with CS-RZ format than with conventional-RZ format, indicating that proper encoding of conventional-RZ and CS-RZ was realized with this prototype transceiver. In the case of CS-RZ format, the error free (BER < 10-9) transmission over 720 km was achieved with the long repeater amplifier span of 120 km.
