OSP Network Architecture & Design Standards 2

Question 1

In a fiber-to-the-premises (FTTP) architecture, what component splits the optical signal from a single feeder fiber to multiple distribution fibers?

Accepted Answer

Passive optical splitter

Answer

A passive optical splitter divides the optical signal from a feeder fiber to multiple distribution fibers without requiring power.

Question 2

Which OSP design standard specifies minimum bend radius requirements for single-mode fiber cables during installation?

Accepted Answer

TIA-5017

Answer

TIA-5017 provides specifications for optical fiber, including minimum bend radius requirements to prevent signal loss or fiber damage.

Question 3

A network designer is planning a GPON deployment. What is the maximum logical reach defined by the ITU-T G.984 standard?

Accepted Answer

40 km

Answer

ITU-T G.984 defines a maximum logical reach of 60 km for GPON, though typical deployments are 20 km.

Question 4

What is the primary purpose of a network topology map in OSP design?

Accepted Answer

To show logical and physical relationships between network elements

Answer

A network topology map documents both the logical relationships and physical layout of network elements to guide installation and troubleshooting.

Question 5

In a ring topology OSP network, what is the key advantage over a simple point-to-point design?

Accepted Answer

Built-in redundancy allowing traffic to reroute if a segment fails

Answer

Ring topology provides path redundancy so that a single cable cut allows traffic to reroute in the opposite direction around the ring.
