1. What is unique about WDM - PON ?: WDM-PON deployed in a greenfield system allows each subscriber to get their own designated wavelength. 2. What is the main benefit of deploying WDM technology?: It will increase the capacity of the existing fiber networks tenfold without adding any more fiber. 3. How are optical splitters used in the forward path?: As passive branching devices that divide an optical signal across multiple output fibers. 4. What is the purpose of a fiber demarcation box?...

Question Answer What was the primary driver for development of IPv6? To address the issue of IPv4 address exhaustion. When comparing IPv4 to IPv6, which of the following statements is true IPv4 uses a 32-bit address scheme, while IPv6 uses a 128-bit address scheme. In IPv6-enabled networks, static addressing is no longer allowed. FALSE Without IPv4's network address translation (NAT), IPv6 offers simpler packet construction and better support for peer-to-peer and...
