Product features
Auto-Negotiation
(Fiber)
Fiber Auto-Negotiation allows the fiber interface to detect and then advertise the
support capabilities of the remote device. It is supported only when the fiber cable
is connected to a device with a negotiating port.
Link Pass-Through
Link Pass-Through allows the media converter to monitor both fiber RX
(receive)
ports for loss of signal. In the event of a loss of the RX signal (1), the media
converter will automatically disable the TX
(transmit)
signal (2), thus, “passing
through” the link loss (3). The far-end device is automatically notified of the link
loss (4), which prevents the loss of valuable data unknowingly transmitted over an
invalid link.
Bandwidth allocation
It allows setting the bandwidth in varied increments, starting at 64Kbps to full
bandwidth.
Rate Limiting based on frame priorities can also be configured. Each higher priority
frame can be configured to get twice the bandwidth of lower priority frames; e.g.,
priority “3” frame configurations can get twice the bandwidth of priority “2”
frames.
Egress bandwidth allocation in 64Kbits/sec increments:
•
Rate limit all frames
Ingress bandwidth allocation in 64Kbits/sec increments with four filter selections:
•
Rate limit all frames
•
Rate limit multicast, flooded unicast, and broadcast
•
Rate limit multicast and broadcast
•
Rate limit broadcast
