FIBER ACCESS
Datasheet
Transparent Bandwidth Limiter
Features
Limits and monitors data carrier speed for
implementation of SLAs
Supports four protocol transparent service levels*:
< 45 Mbps (Level 1), < 155 Mbps (Level 2), < 622
Mbps (Level 3), and < 1 Gbps (Level 4)
Three over-limit response options (with or without
management notification):
No action
Intermittent disruption of transmission
Disable link
Management reporting of real-time data carrier speed
DIP switches for easy onsite configuration of
service level and over-limit response
Overview
The leasing of "dark" fiber to customers looking for dedicated and
secure high-speed data connectivity gives service providers a means
of generating revenue from otherwise unused or under utilized fiber
plant. By being able to offer service level agreements (SLAs) to their
customers, providers can maximize the potential of this revenue
source.
Implementing and maintaining SLAs, however, can present a problem.
Different customers will use their leased fiber for different purposes.
One customer may use ATM, another Gigabit Ethernet, and yet another
Fibre Channel. Typically, to support and manage these different types
of leased fiber networks would take a substantial investment in
protocol specific, SLA-enable switches and routers. The Fiber Driver
Transparent Bandwidth Limiter (TBL) presents a simpler, cost-effective
alternative to this type of deployment.
Link distances of up to 80 km over Singlemode dual
fiber, 50 km over Singlemode single fiber, and 6**
km over Multimode fiber or Multimode single fiber
SNMP support when used with the Fiber Driver
Network Management Module
Supports Loopback and LIN
Front panel diagnostic LED indicators
Hot swappable
Compatible with all Fiber Driver products and technologies,
including media converters, WDMs and OADMs
* Monitors digital transitions of carrier signal
** 2 km guaranteed. Maximum range depends upon grade and
condition of fiber plant used.

FIBER ACCESS
The Fiber Driver TBL functions at the network physical
layer measuring the digital transitions of the carrier signal,
so it is able to monitor and limit the usage of a fiber optic
link while remaining protocol transparent. A high level of
security is maintained as the device never reads or taps
into the user data stream. This technology allows for
greater ease and flexibility of deployment as the unit can
be placed in virtually any environment with little
configuration. Most importantly, its operation remains
transparent to the user.
The TBL provides up to four carrier provisioning levels: <
45 Mbps (Level 1), < 155 Mbps (Level 2), < 622 Mbps (Level
3), and < 1 Gbps (Level 4). The desired provisioning level
can be set using on-board DIP switches, or set remotely
using the optional in-band SNMP management agent.
Once in place, it continuously monitors the carrier speed
of the optical link. If usage exceeds the assigned service
level, the unit will respond in one of three possible ways:
no action is taken, the data carrier signal is disrupted for
one second every five seconds, or the link is disabled. For
each type of response, management notification can be
enabled or disabled. Like the provisioning level, the type
of response can be set using on-board DIP switches, or set
remotely via SNMP.
It is important to note that because it is the speed of the
carrier signal that is measured and not the amount of data
being transmitted, that if, for example, a Gigabit Ethernet
device is connected to a link limited to 45 Mbps an over
limit response will be triggered even if no actual data is
transferred.
The Fiber Driver TBL is available with either Multimode or
Singlemode optics. Link distances of up to 80 km can be
achieved over Singlemode dual fiber, up to 45 km over
Singlemode single fiber, and up to 6* km over Multimode fiber
using our exclusive Multimode Extender (MX) technology.
When paired with the Fiber Driver Network Management
Module, several management interfaces are supported,
including the graphical interface of MegaVision Web™,
our own comprehensive network management system
(NMS), HP OpenView, or any other SNMP compliant NMS.
Access to the built-in Command Line Interface (CLI) is
available through Telnet, and via an RS-232 serial
interface.
Front panel diagnostic LED indicators, loopback, and
Link Integrity Notification (LIN) functionality are
standard. With LIN enabled, if one port on the module
loses connectivity, the other port is automatically
disabled in order to maintain end-to-end link state
continuity.
The Transparent Bandwidth Limiter is a single slot, hot
swappable module that fits any powered Fiber Driver
chassis. It is compatible with all Fiber Driver products and
technology, including media converters, Wave Division
Multiplexers (WDMs), and Optical Add/Drop Multiplexers
(OADMs).
