xDSL Access

• Although more and more ISPs are deploying or
  considering deploying FTTx network, but xDSL
  still remains the dominant service for most users
  across the world, especially in developing
  countries. Considering the transmission distance,
  speed and terminal cost, ADSL2 and VDSL2 are
  most popular among different xDSL technologies.
  As a leading Huawei xDSL solution provider,
  Huanetwork can offer Huawei ADSL2 and VDSL2
  products at a Favourable price, also the delivery
  time is only in several business days.
• ADSL2 is an extension of ADSL, and also an
  asymmetric transmission technology that transmits
  data at a high speed over twisted pairs. The
  maximum upstream and downstream rates can reach
  2.5 Mbit/s and 24 Mbit/s, respectively. The
  maximum transmission distance is 6.5 km.
• VDSL2(Very-high-speed digital subscriber line 2)
  provides symmetric or asymmetric high-speed
  access services over twisted pairs. It can
  increase the upstream/downstream access rates to
  symmetric 100 Mbit/s over a short distance
  (within 300 m), addressing the requirements for
  bandwidth-critical services such as
  high-definition (HD) video services. VDSL2
  enables digital subscriber line access
  multiplexers (DSLAMs) to implement the "last
  mile" access, especially when the DSLAMs are
  deployed in fiber to the building/fiber to the
  curb (FTTB/FTTC) networks. What's more,VDSL2 is
  compatible with ADSL, ADSL2, and ADSL2
  terminals.

• Comparison between VDSL2 and ADSL/ADSL2/ADSL2/VDS
  L1 in terms of downstream rate and reach
• The preceding figure shows that
• VDSL2 provides a remarkably higher downstream
  rate than ADSL/ADSL2/ADSL2/VDSL1 within a 0.3 km
  reach. VDSL2, however, provides the theoretical
  100 Mbit/s downstream rate only when the reach is
  within 0.25 km.
• VDSL2 provides the same downstream rate as VDSL1
  and ADSL2 at a 1.2 km reach
• VDSL2 produces the same rate curve as ADSL2 at a
  reach over 1.2 km.

• Huawei xDSL Network
• As shown in the right figure, typical scenarios
  of xDSL network applications are as follows.
• The MA5600/MA5616 provides the xDSL access. On
  the user side, CPEs can be connected to the
  MA5600 to provide high-speed Internet access
  service.
• The OLT(MA5600T Series) provides GPON optical
  ports for connecting to MA5616 and MA5616 provide
  the xDSL access. In the upstream direction, the
  MA5616 are connected to the OLT by PON. The
  FTTxxDSL network topology addresses the distance
  restriction on the ADSL2 access.
• Both MA5616 and MA5600 can support Cascading so
  as to meet different requirements.

• Among Huawei DSLAM products, MA5600 and MA5616
  are common stock at Huanetwork. MA5600 is
  designed as big capacity DSLAM, and MA5616 is for
  small site. For details refer to the details in
  the following Table.
