Gigabit Ethernet and 64E1 to optical fiber multiplexer (RP104)

The RP104 is optical transmission equipment based on Application Specific Integrated Circuit (ASIC),realizes the 64 E1 and four 1000Mbps Ethernet data channel transmission over optical line of 1.25Gb/s, the four 1000Mbps Ethernet data channel share 1000M bandwidth. In point-to-point mode, the Ethernet transmission bandwidth can be doubled to 2G by setting the port-trunking function.

Product Description

Overview 

The RP104 is optical transmission equipment leveraging Application Specific Integrated Circuit (ASIC) technology. It facilitates the transmission of 64 E1 and four 1000Mbps Ethernet data channels over an optical line at a speed of 1.25Gb/s, with the four 1000Mbps Ethernet data channels sharing a 1000M bandwidth. In a point-to-point configuration, the Ethernet transmission bandwidth can be doubled to 2G by enabling the port-trunking function.

This equipment supports management through the Command Line Interface (CLI), allowing users to monitor and configure the device using a PC-integrated super terminal. Additionally, it is compatible with the Simple Network Management Protocol (SNMP).

Boasting low power consumption, high integration, and robust stability, the RP104 presents a cost-effective solution for applications demanding simultaneous gigabit Ethernet and E1 functionality. This includes sectors such as telecommunications, electric power, and finance.

Features

The RP104 features a compact design, occupying 1U height in a 19'' rack, making it suitable for standard rack installations. Key capabilities include the multiplexing of 64E1 and four 1000M Ethernet channels over optical fiber.

Application

RP104 supports point-to-point, point-to-dual point, ring and chain network application, refer to Figure 3-1, Figure 3-2, Figure 3-3 and Figure 3-4 shows:

In point-to-point topology, the Ethernet transmission bandwidth can be doubled to 2G by setting the port-trunking function.

Figure 2 Point-to-dual point application

In ring and chain topology, there can be several RP1000 equipment (Gigabit Ethernet and 16E1 optical fiber multiplexer with 4/8/16 E1,3 copper gigabit Ethernet interfaces and one fiber gigabit Ethernet interface), each RP1000 occupy 4/8/16 E1.

Note:The optical line can multiplex one path of GE signal and up to 80 E1s.
