What is the effective bandwidth of a 6 node, four-fiber OC-48 BLSR ring if all the traffic
What is the effective bandwidth of a 6 node, four-fiber OC-48 BLSR ring if all the traffic on the ring is homed back to one node (hub-and-spoke) without Protection Channel Access (PCA)?

The graph represents optical signal power versus wavelength measurement from 1550nm to 1560nm. The laser type that provides very narrow spectral widths, (<100kHz) in the 1550nm range for DWDM applications (as shown in the graph), is an example of a:
When this is detected, the retransmission is sent by

Host 1 and Host 2 are on Ethernet LANs in different buildings. A serial line is installed between two Cisco routers using Cisco HDLC serial line encapsulation. Routers A and B are configured to route IP traffic. Host 1 sends a packet to Host 2. A line hit on the serial line causes an error in the packet. When this is detected, the retransmission is sent by:
