About H3C 5G extended pico stations
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 Interface (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.

Assembling 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 assembly 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 6.2dB. · Please take protective measures such as dust and pressure prevention for the assembled hybrid copper-fiber cable. · When assembling LC fiber connectors using fusion splicing, please install a protective fiber box on the fusion sleeve to protect it from being pulled or bent, thus avoiding damage. |
Removing the outer jacket of the hybrid copper-fiber cable
Strip the outer jacket of the hybrid copper-fiber cable at both ends, with a length of 50cm. To facilitate the stripping of the outer jacket and prevent accidental fiber breakage, it is recommended to strip it in 2 to 3 segments.
|
|
IMPORTANT: · Do not damage the power cord (PWR) core wire and the Optical fiber core. · Do not forcefully bend the hybrid copper-fiber cable or peel off the outer jacket. · In order to facilitate on-site cable hiding, you can increase the stripping length appropriately. |
Figure1-9 Removing the outer jacket
Assembling LC-type fiber connector
1. Use a butterfly-shaped fiber stripper to strip the fiber sheath, with a length of 5cm.
Figure1-10 Strip fiber sheath
2. Install the optical fiber core wire to the LC fiber connector by cold or fusion splicing. The fiber length shown in Figure1-11. can be used as a reference length for cold splicing. If using fusion splicing to assemble the LC fiber connector, please make appropriate adjustments according to the length of the fiber to be spliced and the on-site environment.
Figure1-11 Connect LC fiber connector
3. Test the assembled fiber to ensure it is functioning properly.
Assembling the RJ-45 power connector (product code 1408A047)
1. Trim the power cord at the rear of the LC fiber connector, with the trimmed length less than 8mm, as shown in Figure1-12.

2. As shown in Figure1-13, connect the power cord to the RJ-45 type power connector, the specific steps are as follows: Figure1-13
a. Peel off the insulation layer of the power cord wire, the length of the peeling is 5mm.
b. Insert the two power cord (PWR) cores into the bottom of the power connector cable access hole, ensuring that the copper wire is not bent or exposed. Note that the positive (A) and negative (B) identify (ID) on the connector, and the positive and negative ends of the same power cord core need to be consistent.
c. Tighten the connection with a screwdriver to prevent the power cord (PWR) from coming loose.
Figure1-13 Connecting the RJ-45 type power connector
3. Pull the power cord outward with force. If the power connector does not come off, then the power cord is connected properly.

Ethernet twisted pair cable
Introduction
An Ethernet twisted pair cable consists of four pairs of insulated copper wires twisted together. Every wire uses a different color, and has a diameter of about 1 mm (0.04 in). A pair of twisted copper cables can cancel the electromagnetic radiation of each other, and reduce interference of external sources. An Ethernet twisted pair cable mainly transmits analog signals and is advantageous in transmitting data over shorter distances. It is the commonly used transmission media of the Ethernet. The maximum transmission distance of the Ethernet twisted pair cable is 100 m (328.08 ft). To extend the transmission distance, you can connect two twisted pair cable segments with a repeater. At most four repeaters can be added, which means five segments can be joined together to provide a transmission distance of 500 m (1640.42 ft).
Ethernet twisted pair cables can be classified into category 3, category 4, category 5, category 5e, category 6, and category 7 cables based on performance. In LANs, category 5, category 5e, and category 6 are commonly used.
Table1-16 Description for commonly used Ethernet twisted pair cables
|
Type |
Description |
|
Category 5 |
Suitable for data transmission at a maximum speed of 100 Mbps |
|
Category 5e |
Suitable for data transmission at a maximum speed of 1000 Mbps |
|
Category 6 |
Suitable for data transmission at a speed higher than 1 Gbps |
Based on whether a metal shielding is used, Ethernet twisted pair cables can be classified into shielded twisted pair (STP) and unshielded twisted pair (UTP). An STP cable provides a metallic braid between the twisted pairs and the outer jacket. This metallic braid helps reduce radiation, prevent information from being listened, and eliminate external electromagnetic interference (EMI) of external sources. STPs have strict application requirements and are expensive although they provide better EMI prevention performance than UTPs, so in most LANs, UTPs are commonly used.
An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two ends. Figure1-15 shows the pinouts of an RJ-45 connector.
Figure1-15 RJ-45 connector pinout
|
|
NOTE: To power the pRRU through an Ethernet twisted pair cable, make sure the Ethernet cable is a Category 5e or above cable. |
EIA/TIA cabling specifications define two standards, 568A and 568B, for cable pinouts.
· Standard 568A—pin 1: white/green stripe, pin 2: green solid, pin 3: white/orange stripe, pin 4: blue solid, pin 5: white/blue stripe, pin 6: orange solid, pin 7: white/brown stripe, pin 8: brown solid.
· Standard 568B—pin 1: white/orange stripe, pin 2: orange solid, pin 3: white/green stripe, pin 4: blue solid, pin 5: white/blue stripe, pin 6: green solid, pin 7: white/brown stripe, pin 8: brown solid.
Ethernet twisted pair cables can be classified into straight-through and crossover cables based on their pinouts.
· Straight-through—The pinouts at both ends are T568B compliant, as shown in Figure1-16.
· Crossover—The pinouts are T568B compliant at one end and T568A compliant at the other end, as shown in Figure1-17.
Figure1-16 Straight-through cable
Select an Ethernet twisted pair cable according to the RJ-45 Ethernet port type on your device. An RJ-45 Ethernet port can be MDI (for routers and PCs) or MDIX (for switches). Table1-17 and Table1-18 show their pinouts.

To ensure normal communication, the pins for sending data on one port must correspond to the pins for receiving data on the peer port. When both of the ports on the two devices are MDI or MDIX, use a crossover Ethernet cable; when one port is MDI and the other is MDIX, use a straight-through Ethernet cable. To summarize, straight-through and crossover cables connect the following devices:
· Straight-through cables connect devices of different types—for example, router to PC and router to switch.
· Crossover cables connect devices of the same type—for example, switch to switch, router to router, and PC to PC.
If an RJ-45 Ethernet port is enabled with MDI/MDIX autosensing, it can automatically negotiate pin roles.

NOTE: The RJ-45 Ethernet ports on the device support MDI/MDIX autosensing. |
Making an Ethernet twisted pair cable
1. Cut the cable to a required length with the crimping tool.
2. Strip off an appropriate length of the cable sheath. The length is typically that of the RJ-45 connector.
3. Untwist the pairs so that they can lay flat, and arrange the colored wires based on the wiring specifications.
4. Cut the top of the wires even with one another. Insert the wires into the RJ-45 connector and make sure the wires extend to the front of the RJ-45 connector and make good contact with the metal contacts in the RJ-45 connector and in the correct order.
5. Crimp the RJ-45 connector with the crimping tool until you hear a click.
6. Use a cable tester to verify the connectivity of the cable.
