Autocross
Autocross allows for automatic detection of the correct MDI / MDIX configuration on
the copper ports (RJ-45), eliminating the need to specify different cables (crossover
or straight-through) and thus eliminating another step in troubleshooting.
Auto Negotiation
Auto Negotiation allows devices to automatically assign the most efficient line speed
(10/100/1000 Mbps) and mode (Full-Duplex or Half-Duplex) for a particular network
segment between two devices.
Coarse Wave Division Multiplexing
Coarse Wave Division Multiplexing (CWDM) uses uncooled lasers
to combine multiple wavelengths (four, eight or 16; from 1310 nm to
1610 nm) onto a single fiber, using an ITU standard 20 nm spacing between the
wavelengths. Adding wavelengths to the same fiber increases capacity, making
CWDM technology a sound choice for large networks such as Gigabit Ethernet and
Fibre Channel-based Metropolitan Area Networks (MAN).
Config Control
Configuration Control has been implemented on select iMcV-Modules. Its main
function is to assist the end-user by retaining the latest configuration regardless of
how the initial configuration was setup, whether through DIP Switch settings or the
SNMP Management Module’s configuration.
FiberAlert
FiberAlert minimizes the problems associated with the loss of one strand of fiber.
If a strand is unavailable, the device at the receiver end notes the loss of link. The
device will then stop transmitting on the fiber until a signal or link pulse is received.
The result is that the link LED on BOTH sides of the fiber connection will go out
indicating a fault somewhere in the fiber loop.
Industrial Ethernet / Equipment (IE)
IE stands for “Industrial Ethernet” and refers to B&B Electronics’ designation for
products that have been designed to operate in a wider temperature range rather
than the typical 0°C to +40°C. B&B Electronics’ “IE” products contain additional
features designed for industrial applications, such as multiple powering options
and DIN clips. IE temperature ranges vary, so check the product specifications
for more details.
IE products require third party enclosures for outdoor installations or protection from
moisture, dust and other harsh environmental factors. External protection is also
required for lightning or other serious power surges.
Last Gasp
The Last Gasp feature available on select B&B Electronics modules allows for one
final health status message to be sent when remote modules lose power, notifying
network operators that a field visit is necessary.
Link Fault Pass-Through (LFPT)
LFPT (Link Fault Pass-Through) – A feature that allows a segment of a network,
divided by a media converter, to act as if it was one physical piece of media. It
does this by passing a link fault from one side of the media converter to the other.
If a link is lost on one side of the media converter the converter forces a link fault
on the other.
LinkLoss
LinkLoss is a troubleshooting feature that works on either the twisted pair port
(TP/TX) or the fiber port (FO/FX) of devices which have at least one of each port
type. When a fault occurs on one segment of a conversion, LinkLoss detects the
fault and passes this information to the other segment. For example, if a media
converter is not receiving a fiber link, FO/FX LinkLoss disables the transmitter on
the media converter’s twisted pair port. This results in a loss of link on the remote
twisted pair device.
Managed Products
B&B Electronics offers several products that support SNMP management, allowing
operators to proactively manage and monitor their devices from a remote location
.
On Board SNMP Management
B&B Electronics offers “intelligent” products with on board SNMP management,
allowing operators to proactively manage and monitor the devices without an additional
management controller.
Power Over Ethernet (PoE)
Power Over Ethernet (PoE) is a standards based (IEEE 802.3af) method of delivering
power over twisted-pair network cables (RJ-45) along with data, thus eliminating the
need for a separate run for a power source. There are two types of PoE devices: the
Power Sourcing Equipment (PSE) and the Powered Device (PD). The PSE supplies
power to the PD.
Q-in-Q
Q-in-Q, also known as Extra-Tagging, is an IEEE 802.1Q compliant method of assigning
a VLAN tag to already tagged network traffic. Q-in-Q enables the transmission of data
across multiple VLANs without altering the original data, providing safer and more
secure transmission of data packets over the network.
RoHS
With environmental protection becoming more important across the globe, B&B
Electronics has taken a leadership position by designing products that are free of lead,
cadmium and 6 other toxic materials. This makes the products of B&B Electronics
compliant with the Restriction of Hazardous Substances in Electrical and Electronic
Equipment Directive (RoHS), passed into law by the European Union. All part numbers
starting with “8” are RoHS compliant.
Single-Strand Fiber
Single-Strand Fiber technology allows two wavelengths to share one fiber strand. Full-
Duplex data travels on different wavelengths (1310 nm and 1550 nm) which effectively
doubles the capacity of installed fiber. Since single-strand fiber products use optics that
transmit and receive on two different wavelengths, single-strand fiber products must be
deployed in pairs. The pair can consist of two IMC or third-party products that conform
to the same IMC standard.
Traffic Prioritization
Traffic Prioritization (IEEE 802.1p) provides advanced packet management of network
traffic by assigning a priority ID to each packet, insuring that high-priority traffic (such
as VoIP) receives the network resources and bandwidth necessary for high Quality of
Service (QoS).
Unified Management Agent (UMA)
The Unified Management Agent (UMA) is a proprietary system developed by B&B
Electronics to utilize a separate management domain on the network in order to keep
management and other data separate. UMA is an IP-less management method which
simplifies management of supported devices by reducing the number of IP addresses.
VLAN Tagging
VLAN Tagging (IEEE 802.1Q) involves assigning identification information to data
packets on a network to insure that data is efficiently and correctly routed between
devices. The VLAN tag includes an EtherType, priority bits and a VLAN ID that allows
each packet to remain secure and intact while being routed across multiple networks.
Administration and Maintenance
IEEE 802.3ah OAM includes features associated with Discovery, Link Monitoring,
Events, Remote Loopback and Performance Monitoring and Reporting. B&B
Electronics’ implementation of 802.3ah supports both Active and Passive operational
modes on all ports and software upgrades are Free to B&B Electronics clients.
