In these networks, most of the data processing will be performed electronically. Therefore, it is essential for a receiver node to buffer the incoming ultrahigh-speed (100 Gbit/s) optical data packets, rate convert the data to electronic rates (100 MHz-10 GHz), detect and process the data. Rate-converted data is a time-dilated version of the original data, and as such, differs from demultiplexed data. Time dilation of clock and data streams to low rates has been used as a pulse-characterization technique. Such schemes enabled characterization of narrow pulses without high-speed photodiodes or mechanical translation stages. We demonstrate that an optical sampling technique maybe used to achieve rate conversion in network applications where the desired time-dilated data stream rates range from 100 MHz-10 GHz. We demonstrate all-optical rate conversion of 10 Gbit/s data packets to 100 Mbit/s, 200 Mbit/s, 400 Mbit/s, 600 Mbit/s, and 800 Mbit/s data packets. The variation in the converted data rate is achieved using a tunable-repetition-rate sampling source. Extension of this technique to rate-converting 100 Gbit/s data streams is straightforward and will be discussed.","PeriodicalId":133333,"journal":{"name":"Proceedings of Optical Fiber Communication Conference (","volume":"255 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122535814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An effective way to avoid this distortion is the use of an optical duobinary signal, which has only half the spectrum bandwidth of a conventional intensity modulation (IM) signal. For generating optical duobinary signals, two types of modulation schemes are well known; a low-pass filtering (LPF) method and an electrical one-bit delay method. From computer simulation results for both modulation schemes, we have found that the LPF method shows larger suppression for the optical spectrum side-lobes and has more tolerance against the fiber dispersion than the one-bit delay method. Therefore, we employed the LPF method to evaluate dispersion tolerance of the optical duobinary signal. By using a newly developed, high-speed optical duobinary transmitter and receiver, more than 40-km standard fiber [1.3-/spl mu/m zero-dispersion single-mode fiber] transmissions have been demonstrated at 20 Gbit/s. The result indicates the robustness of optical duobinary signals against dispersion in high-capacity, long-distance transmission.","PeriodicalId":133333,"journal":{"name":"Proceedings of Optical Fiber Communication Conference (","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121285570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have previously proposed the use of a fiber-embedded circuit for a WDM receiver module. Because the fiber-embedded circuit is an in-line device, as opposed to a line-terminating device, this approach can be extended to include a passively aligned LD for the transmitter function. We demonstrate a novel WDM transceiver module with a hybridly integrated 1.3-/spl mu/m laser diode and 1.55-/spl mu/m PIN photodiode, which were passively aligned to a fiber-embedded circuit.

A serious doubt has recently been cast on the DBR laser aging behavior. Based on an accelerated aging study performed on DBR lasers, exhibiting relatively poor characteristics, this previous work demonstrates that the tuning section degrades more rapidly than the active section.","PeriodicalId":133333,"journal":{"name":"Proceedings of Optical Fiber Communication Conference (","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116983452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
