BBU is connected to RRH using single-mode fiber optic cable.

• Single-mode fiber optic cable is used for long distance communication.

• It has a smaller core diameter than multimode fiber optic cable.

• It allows for higher bandwidth and longer transmission distances.

• It is commonly used in telecommunications and data centers.

• Examples of single-mode fiber optic cable include OS1 and OS2.

The power dbm in BBU to RRH is determined by the distance between them and the required signal strength.

• The power dbm is dependent on the distance between the BBU and RRH.

• The required signal strength also plays a role in determining the power dbm.

• Factors such as obstacles and interference can affect the power dbm.

• The power dbm can be adjusted through the use of attenuators or amplifiers.

Private IP is used within a network while public IP is used to communicate over the internet.

• Private IP is assigned to devices within a local network and is not visible to the internet.

• Public IP is assigned by the internet service provider and is used to communicate over the internet.

• Private IP addresses are in the range of 10.0.0.0 to 192.168.0.0.

• Public IP addresses are unique and can be traced back to a specific devi...read more

Modem connects to the internet, router connects devices to the network, switch connects devices to each other.

• Modem converts digital signals to analog for transmission over phone lines or cable lines.

• Router directs traffic between devices on a network and connects to the internet through a modem.

• Switch connects devices to each other within a network.

• Example: Modem - cable modem, Router - Linksys router, Switch - Netgea

ARP (Address Resolution Protocol) is used to map a network address (such as an IP address) to a physical address (such as a MAC address).

• ARP is used in Ethernet networks to find the MAC address of a device based on its IP address.

• When a device needs to send data to another device on the network, it sends an ARP request asking for the MAC address of the destination device.

• The destination device responds with its MAC add...read more

IPSEC messages are used for secure communication. Troubleshooting scenarios include connectivity issues and misconfigured settings.

• IPSEC messages are used to establish and maintain secure communication between two devices

• Common troubleshooting scenarios include connectivity issues, such as failed VPN connections

• Misconfigured settings can also cause IPSEC issues, such as incorrect encryption or authentication settings

• To...read more
