Hi John and ad-hoc participants, During yesterday’s call remarks were made with respect to slide 11, that installed modems would have a higher speed capability than actually used. Just to confirm that observation I would like to share some information on installed subscriber modems in the Netherlands. In the Netherlands there is a strong competition between cable operators and the incumbent KPN. Due to this competition an increasing download speed capability is being offered to the end-user, which is good for them. ADSL (offered by KPN and other providers) no longer provides sufficient speed to compete with the offers from the cable operators (docsis3) and therefore they are currently starting to offer VDSL solutions. Of course this has nothing to do with the actual download speeds being used. Within this competitive field there is also a strong take-off of FTTH networks. Several organizations are investing heavily in connecting every home with fiber in point-2-point infrastructures (only passive). Currently there are about 250k new (passive) connections each year on a total of 5-6M homes in NL (16.5M inhabitants). The strongest limitation is actually installation capacity (workforce) for digging, splicing, etcetera. In selected towns projects will start when at least 30-40% of the homes have decided to sign up for activation. Initially homes were activated with CPE’s operating at 100Mbps, via 100BASE-BX10 connections. These FTTH initiatives are a strong competitor to the cable offerings (not ADSL or VDSL) and therefore cable companies are offering internet speeds in access of 100Mbps. As a response to this the FTTH operators, including incumbent KPN, have started deploying fiber CPEs or NTs, capable of operating at 1000BASE-BX10, thus 1GE speeds, which initially will operate at 100Mbps (FE)
speeds. In this way it is avoided to equip the CO equipment with the more expensive 1GE SFPs (as long as 100 Mbps is sufficient), while at the same time CPEs can stay untouched in the homes for a longer period. Of course this is related to the fact that CPE cost for 1GE is only a percentage (and not a factor) higher than for Fast Ethernet. So in summary, yes, also in the Netherlands we are seeing modems being installed for both cable and FTTH networks, which can operate in excess of 100 Mbps up to 1Gbps. Example of packages being offered by one FTTH operator: ·
Internet, phone, TV, 30Mbps up AND down ·
Internet, phone, TV, 50Mbps up AND down ·
Internet, phone, TV, 100Mbps up AND down So despite the information in yesterday’s presentation, in NL the FTTH operators still offer symmetrical up/download speeds, but of course this may change in the future. The point-2-point technology however offers
the symmetrical (optical) capability. If there are comments/questions, please let me know. I will be at the 802.3 meeting next week. Kind regards, Peter Stassar Technical Director Huawei Technologies Ltd Karspeldreef 4, 1101CJ Amsterdam The Netherlands Tel: +31 20 4300 832 Mob: +31 6 21146286 |
