RHUB5921
The RHUB5921 converges CPRI data from remote RF modules and provides the following functions:
Equipment Specifications | RHUB5921 |
Input Power Supply Capability | 90V to 290V AC |
Dimensions (H x W x D) | 43.6 mm x 442 mm x 310 mm |
Weight | ≤ 6 kg |
Power Supply Capability | 8 x 99.9W: 99.9W over each CPRI_E port (a total of eight CPRI_E ports) |
Environment Specifications | RHUB5921 |
Operating Temperature | Long-term operation: –20°C to +55°C Short-term operation: +55°C to +60°C |
Storage Temperature | –40°C to +70°C |
Relative Humidity | 5% RH to 95% RH |
Operating Atmospheric Pressure | 70 kPa to 106 kPa |
IP Rating | IP20 |
Operating Environment | ETSI EN 300 019-1-3 Class 3.2 ETSI EN 300 019-2-3 |
Noise Sound Power Level | ETSI EN 300 753 ≤ 6.3 bels |
Storage Environment | ETSI EN 300 019-1-1 Class 1.2 |
Transport Environment | ETSI EN 300 019-1-2 Class 2.3 ETSI EN 300 019-2-2 |
Anti-Seismic Performance | ETSI EN 300 019-1-3 ETSI EN 300 019-2-3 YD 5083 |
Surge Protection Specifications | RHUB5921 |
Port | Power port |
Application Scenario | Indoor |
Surge Protection Mode | Differential mode Common mode |
Surge Protection Specifications | Differential mode:2 kV (1.2/50 μs) Common mode:4 kV (1.2/50 μs) |
CPRI Port Specifications | RHUB5921 |
CPRI Port Description | CPRI0/CPRI1: Optical ports used for signal transmission between an RHUB and a BBU or between two RHUBs CPRI_E0 to CPRI_E7: Ports used for connecting pRRUs |
CPRI Port Rate | CPRI0/CPRI1: 10.1 Gbit/s CPRI_E0 to CPRI_E7: 10.1 Gbit/s |
CPRI-Based Topology | CPRI0/CPRI1: Chain, Star, or Load-sharing topology CPRI_E0 to CPRI_E7: Star or Load-sharing topology |
Cascading Level | CPRI0/CPRI1: 2 CPRI_E0 to CPRI_E7: N/A |
Remote Transmission Capability | CPRI0/CPRI1: Two RHUBs can be cascaded for RF signal combination. In this case, the maximum optical fiber length between the DCU and the last-level RHUB is 2 kilometers by default but can be extended to 15 kilometers if the radius of the source cell is modified to 35 kilometers. CPRI_E0 to CPRI_E7: At least CAT6a S/FTP shielded Ethernet cables must be used to achieve a data rate of 10.1 Gbit/s over electrical ports on the RHUB5921. The maximum Ethernet cable length between the RHUB5921 and a pRRU is 100 meters but can be extended to 200 meters using a 10.1 Gbit/s extender. |
