Chapter 2 TBC1-1VDSL1SFP Expansion Card
This manual focuses on the TBC1-1VDSL1SFP expansion card.
The SFP (
Small Form-Factor Pluggable
) interface provides connectivity to a single
Gigabit Ethernet
device or to a
network, allowing clients to use different SFPs for special requirements such as distance, cost, existing infrastructure
or future expansions.
VDSL2 stands for Very high bit rate Digital Subscriber Line version 2, which is defined in theITU G.993.2 standard.
VDSL2 has evolved from the ADSL/ADSL2/ADSL2+ technologies and the main differences areas follows:
• Upstream and downstream channel multiplicity.
• Supports up to 200 Mbps, symmetric (profile 30a).
• It only uses FDM mode, EC mode is not defined (echo cancellation or carrier
overlapping).
• Allows for a new encapsulation to be used: PTM.
• Multiple link diagnostics.
For further information on ADSL and VDSL technologies, please see the Teldat-
Dm741-I ADSL-VDSL
manual.
