0. Introductions
   Chair Taka Fujimori briefly explained the history of p1394b Long-haul
   Low Cost (S100) Task Group.

1. Review of Minutes
   The minutes of S100 TG Honolulu meeting Aug 7 is not yet issued
   by the secretary.  Approval of the minutes is delayed to the next
   S100 TG meeting.

2. 1394b August Meeting Report
   Taka Fujimori reported the p1394b Honolulu meeting August 6-8 as:

   a. Draft 0.04 issued, S800-S1600(S3200) 4.5m.
      with enhanced 1394STP copper cable/connector.
      50/125um GI glass fiber is in focus by S800 PMD TG
   b. POF(Plastic Optical Fiber) Draft 0.01(S100-200) submitted to
      S100 TG.  Both POF and HPCF are included.
   c. Modified 8B10B was selected for all speeds.

   Inoue-san asked whether it is possible to discuss 4B5B again in
   p1394b meeting.  Taka answered it may be pretty difficult unless
   thorough study on both modified 8B10B and 4B5B codes is done
   and discovers new good reasons.
   Yoshida-san raised that 4B5B eases implementation of 1394Long at
   S100/200 over UTP and POF.  Yes, this point was enphasized in the
   Hololulu meeting thus makes it possible to satisfy schedules of
   DAVIC, DVB and VESA.  However those good points were disregarded
   because 1394b group voted for the same code for Fiber Channel and
   gigabit Ethernet and Long-haul Low Cost(S100) people seemed a
   minority(10-20%).

3. Action Items
  3.1 PMD GI-POF
     Nakanura-san re-presented the possibility of Graded Index POF
     which was presented in the Honolulu meeting.  Some interesting
     points are:
       1. The cost of POF can be reduced to one hundreds if the volume
          rises 1000 times.
       2. Low-NA GI-POF, called ESKAGIGA, is in production since 1995,
	  giving us a performance of 1GHz@100m.
       3. A new GI-POF fiber is under development targeting speeds of 
          400-800MHz@100m and a loss of << 20dB/100m.
       4. Targets of POFs are:
	  low-NA SI-POF S200     1997/End
	         GI-POF S200-400 1997/End
                 GI-POF 1GHz     1998/End        

  3.2 PMD GI-HPCF
     Sogabe-san also re-presented Hard Plastic Clad Silica Fiber which
     has core/clad diameters of 200/230um.  
     SI-HPCF can achieve 100m S100@650nm(LED) and 100m S200@850nm.
     GI-HPCF can achieve 100m S200@650nm(LED) and 100m S400@850nm.
     High-NA HPCF allows coupling with LED and reduces bend loss.
     Crimp&Cleave connector eases assembling work.

     Morikura-san repeated his Honolulu presentation.
     850nm LED and Si pin-PD with GI-HPCF are suitable for S100/S200
     at up to 300m.  They can also realize S100/S200/S400 at up to
     100m.  HPCF has wide bandwidth, low loss and easy to handle.

     HPCF can also run with 650nm LED which make it possible to share
     the same optical link with POF.  Though HPCF is a bit costly
     compared to POF(very cheap), it compelements POF in terms of
     distance(100m).

  3.3 PMD POF S200 & follow-up
     Yamazaki-san explained the first POF/HPCF PMD draft submitted to
     Honolulu S100 TG meeting this August.  It addresses both POF(50m)
     and HPCF(100m) at upto S200 with a single optical Link of 650nm.
     He said that this spec was extended from ATM Forum's POF/HPCF
     PMD of 155Mbps spec.  The optical power budget is optimized to
     accomodate both POF and HPCF at S100/200.  However there's no
     power budget left for POF adapters at S200@50m while maintaining
     suggested error rate of 10^-12.  

     As no one had expressed objections with this proposed draft since
     last Honolulu meeting, this draft was unanimously accepted as a
     POF/HPCF PMD working draft of S100 TG.

     Yamazaki-san also suggested to create a POF/HPCF PMD sub task group
     within S100 TG to expedite the work of POF/HPCF among experts.
     The group agreed to make a new POF/HPCF PMD subTG.

4. New Business
   No new work item is raised.

5. Review of Action Items
   No action items remain so far, since the 1394b addresses the coding
   scheme and POF/HPCF PMD subTG treats POF and HPCF issues.
   Next meeting will be called when POF/HPCF PMD subTG comes up with
   a new fruit.  
       
6. Adjournment
   The meeting adjourned around 15:30.
