An H3C 5G extended pico station is an indoor distributed wireless access system, featuring simple architecture, ease of deployment, low maintenance, and deep multi-standard coverage. As shown in Figure1-1, an H3C extended pico station contains three parts:

· BBU—Baseband processing unit for the 5G extended pico station, providing device management, configuration management, performance monitoring, clock management, signaling processing, baseband resource management, and wireless resource management.

· FSW—Extension unit of the 5G extended pico station. It connects to the BBU or subordinate FSW through fiber and accesses the pRRU through a hybrid copper-fiber cable to provide power.

· pRRU—Radio frequency remote unit for the 5G extended pico station, providing the following features:

¡ The transmit channel receives digital signals from the BBU enhanced Common Public Radio Port (eCPRI) port, performs digital-to-analog conversion, frequency modulation, and amplification filtering, and ultimately transmits the RF signal through the antenna.

¡ The receive channel captures the RF signal from the antenna, amplifies and filters it, performs frequency modulation, converts it to a digital signal, and sends it back to the BBU through the eCPRI port.

The pRRU can be directly connected to the BBU or extended through the FSW to expand the cell scale.

Hybrid copper-fiber cables

About hybrid copper-fiber cables

Hybrid copper-fiber cable is a type of fiber cable and electrical cable twisted together. It adds insulated conductors to the fiber cable structure, integrating fiber cable and power transmission copper wire, enabling longer transmission distances and suitable for various types of business.

Figure1-4 Structure of a hybrid copper-fiber cable

Hybrid copper-fiber cable specifications

When using hybrid copper-fiber cable, you need to purchase bare wire, RJ-45 power connector, and LC type Fiber connector for on-site wiring. Detailed information about the bare wire and connectors is shown in Table1-15.

Installing a hybrid copper-fiber cable

IMPORTANT:

· Assembly of hybrid copper-fiber cable must be carried out by personnel with experience in optical communication construction, and equipped with professional fiber production and testing tools.

· When using the optical transceiver module with Product code SFP-XG-CPRI-IR-SM1310, please ensure that the optical link attenuation between FSW and pRRU is less than 6dB.

· Do not damage the power cord and fiber core.

· Do not forcefully bend or strip the outer jacket of the hybrid copper-fiber cable.

· In order to facilitate on-site cable hiding, the stripping length can be appropriately increased.

Removing the outer jacket of the hybrid copper-fiber cable

Peel off the outer jacket at both ends of the hybrid copper-fiber cable, with a length of 50cm. To facilitate the peeling of the outer jacket and prevent accidental fiber breakage during peeling, it is recommended to peel in 2-3 segments.

Figure1-5 Removing the outer jacket

Assembling LC-type Fiber connectors

1. Use the butterfly Fiber stripper to strip the Fiber sheath, with a stripping length of 5cm.

Figure1-6 Removing the fiber sheath

2. Install the Fiber core wire into the LC type Fiber connector through cold or fusion splicing. The fiber length can be used as a reference length for cold splicing. If using fusion splicing to assemble the LC type Fiber connector, please adjust it according to the length of the fusion-spliced pigtail and the on-site environment.

3. Connect the LC-type fiber connector.

4. Test the assembled Fiber to ensure it is functioning properly.

Assembling the RJ-45 type power connector

1. Cut the power cord at the rear of the LC type Fiber connector, with a length of less than 8mm, as shown in Figure1-7.

Figure1-7 Cut the power cord

2. As shown in Figure1-8, connect the power cord to the RJ-45 power connector, the specific steps are as follows:

a. Peel off the insulation skin of the cable outside the power cord core wire, with a peel length of 5mm.

b. Insert the two power cord cores into the bottom of the power connector cable access hole, ensuring that the copper wire threads are not bent or exposed. Note, refer to the positive (A) and negative (B) markings on the connector, and ensure that the positive and negative ends of the same power cord core are connected consistently.

c. Tighten the connection with a screwdriver to prevent the power cord from coming loose.

Figure1-8 Connect the RJ-45 type power connector

3. Pull the power cord firmly outward. If the power connector does not come off, the power cord is connected properly.

Figure1-9 Test the RJ-45 power connector

Cooling system

IMPORTANT:

In order to ensure good ventilation:

· It is recommended to leave sufficient space (recommended greater than 60mm) at the air intake vent and ventilation port of the device to facilitate heat dissipation.

· Acknowledge the installation site has a good ventilation and heat dissipation system.

The device consists of a set of efficient ventilation and heat dissipation system composed of body ventilation holes and detachable fan modules, which can ensure that the heat generated by the device can be discharged in a timely manner, improving the stability of device use. The device cooling process is as shown in Figure1-11. When installing the device, please plan the placement of the device in combination with the ventilation design of the environment.

As shown in Figure1-10, when installing devices, please consider the ventilation design of the environment to plan the placement of the devices.
