“…[22][23][24] Confirmation that no excess dispersion penalties appear for broad-spectrum L E D P reinforces the belief that LEDs can be used in installed systems at these bit rates. However, single-mode laser sources had inadequate reliability for use in the loop and were not compatible with near-term cost objectives.…”

“…On the other hand, lower-cost lightemitting diodes, as used in low-bit-rate multimode systems, were known to meet loop reliability requirements.20*21 It has now been demonstrated that LEDs can be used with significant lengths of single-mode fibre at bit rates in the 560-650 Mb/s range. [22][23][24] Confirmation that no excess dispersion penalties appear for broad-spectrum L E D P reinforces the belief that LEDs can be used in installed systems at these bit rates. Conventional 9 1 power-budget analyses, using detailed models of transmitter and receiver performance, including temperature, indicate that LED transmission over 3-4 km of single-mode fibre is possible at rates in the 400-600 Mb/s range.…”

Two forces, service needs and technological advances, are driving the extension of the Integrated Services Digital Network (ISDN) into the broadband area. First, this paper identifies several business and residential services which provide a market pull for broadband ISDN (BISDN). Secondly, it reviews recent advances in optical transmission and broadband switching which provide a technological push. Finally, it describes an experimental broadband prototype constructed to help us better understand the transmission, switching, signaling protocol, software, and service capabilities required for BISDN.

“…[40] With the recent recognition that LEDs could be used with single -mode fiber, first at medium speeds [41,42] and then at high speeds [43,44], emphasis has again been given to these devices for subscriber -loop applications. Here, low -cost sources are needed that can operate with high reliability (on the order of 1Mh) in elevated -temperature applications (50 -65 C ambient, 70 -85 °C device).…”

The edge‐emitting LED, which is less expensive and more reliable than the laser diode, is studied for use in the broadband subscriber loop in combination with a single‐mode fiber. In comparison to the conventional surface‐emitting LED, the present device has a better efficiency in coupling with a single‐mode fiber and has a narrower emission spectrum. In this paper, a method of simple time domain calculation is proposed for the S/N ratio taking into account the wavelength dependence on the dispersion and loss of the fiber, the emission spectrum profile of the edge‐emitting LED, and the pulse response speed. The validity of the computation method and the high‐speed modulation characteristics of the edge‐emitting LED are confirmed through the optical transmission experiment of 600 Mbit/s and 20 km with a simple waveform compensation circuit. Further, the temperature characteristic of the edge‐emitting LED is studied since it is important in the application to a practical system. A method for temperature compensation is investigated. Finally, based on these studies, the maximum transmission distance is studied in which the temperature variations of the optical output, center emission wavelength and the spectral width as well as the device fluctuation are considered. It is shown that the present edge‐emitting LED is capable of an application to broadband ISDN and optical CATV subscriber loops.
