Patent EP-0887670-A2 (EP)
Inventor: CHANG KAI HUEI
IPC: C03B37/012
Filed: 1998-06-09
Abstract: A singlemode optical fiber [700] having very low loss at 1385 nm, and a
practical method for making same are disclosed. A core rod [20] is fabricated using
vapor axial deposition to have a deposited cladding/core ratio ( D / d ) that is less than
7.5. The core rod is dehydrated in a chlorine- or fluorine-containing atmosphere at
about 1200°C to reduce the amount of OH present to less than 0.8 parts per billion by
weight, and then consolidated in a helium atmosphere at about 1500°C to convert the
porous soot body into a glass. The consolidated core rod is elongated using an
oxygen-hydrogen torch that creates a layer of OH ions on the surface of the rod that
are largely removed by plasma etching. Finally, the core rod is installed in a glass
tube [40] having a suitably low OH content. Thereafter, the tube is collapsed onto the
rod to create a preform [60]. Conventional methods are employed for drawing an
optical fiber from the preform and applying one or more protective coatings [75, 76].
The disclosed method is suitable for commercial production of low-OH fiber.
Significantly, the fiber's loss at 1385 nm is reduced to a level that is less than its loss
at 1310 nm, thereby rendering the entire wavelength region 1200 - 1600 nm suitable
for optical transmission. In particular, wave-division-multiplex systems are now
available to transmit optical signals over distances greater than 10 km in the
wavelength region between 1360 nm and 1430 nm.

Abstract: When a symbol timing detection circuit (107) has
detected a change in symbol generation timing, it
immediately supplies an FFT window signal to an FFT
circuit (103), thereby shifting the position of the FFT
window. At this time, the output phase of the FFT
circuit (103) varies. A window position change
detection circuit (108) detects a change in window
position. A phase correction circuit (105) controls
the output phase of a one-symbol delay circuit (104) in
accordance with the change, whereby the output phase of
the circuit (104) is made to be identical to the output
phase of the FFT circuit (103) supplied to a delay
detection circuit (106). The phase of data obtained
a one-symbol period earlier is corrected in accordance
with the phase of the present FFT output. Thus, normal
demodulation can be executed by delay detection.

Abstract: In a cache system, a non-FSA (Full-Set Associative) cash table (TB,
TC) such as a DM (Direct Mapping) cache table (TB) is coupled with an
FSA cache table (TA). Tag comparison for cache hit judgment is
executed simultaneously in the two cache tables (TA, TB). The number
of cache hits to each cache line of the FSA cache table (TA) is counted by
an access counter, and an access count value concerning the cache hit
count is stored in an access count area (AC) of each cache line. When a
cache hit occurred to a cache line of the FSA cache table (TA), the access
count value of the cache line is incremented by 1. When a miss hit
occurred to both cache tables (TA, TB), the access count values of all the
cache lines of the FSA cache table (TA) are decremented by 1 at once. If
miss hits occurred to both cache tables (TA, TB) when the DM cache table
(TB) has an invalid cache line corresponding to the index of input address
data, data fetched from main memory (21) due to the miss hits is written
into the invalid cache line corresponding to the index. If the miss hits
occurred when the DM cache table (TB) has no invalid cache line
corresponding to the index and the FSA cache table (TA) is full of valid
cache lines, data stored in the miss hit cache line of the DM cache table
(TB) is transferred to one of cache lines of the FSA cache table (TA)
having the smallest access count value, and data fetched from the main
memory (21) is written into the miss hit cache line of the DM cache table
(TB). By such data management/transfer, the cache hit rate and data
access speed are increased to higher levels.
