4.7 Cables
4.7.1 Electrical Power Supply
This GPON system operates from a supply voltage with -48VDC nominal value. It can work up from -40.5VDC to -57VDC in accordance with the
recommendation ETSI EN 300 132-2 V2.1.1 (2003-01). The ground terminals links comply with the provisions of the recommendation ETSI ETS 300
253: January 1995.
- 48 V
Figure 4-6: Electrical power supply H03VV-F cables connection kit
The OLT electrical power supply inputs connection use H03VV-F cables which are provided with terminals as indicated in Figure 4-6. These cables
consist of 6mm2 section and a length of 3m (GND – Green with Yellow stripes, -48V DC Blue and 0V-RTN DC Red), Figure 4-6.
4.7.2 ETH 10/100/1000 BASE-T
For the ETH 10/100/1000 BASE-T interfaces are used RJ45 connectors as indicated in the figure below. The expected range is 100m using UTP
network cable category 5e or higher.
Figure 4-7: Ethernet Cable
The ETH interface with an RJ45 connector is used for the management port (10/100 BASE-T) of the Switch Fabric card.
4.7.3 Alarms & Synchronism
Through a Metral 2mm (FCI TM) plug, available on the front panel of the Switch Fabric card, are provided one junction for synchronism (Rx and Tx)
at 120 or 75 Ohm, alarms, conditions and system ACK.
