YUNPAN top rated digital transmission equipment products for communication

PRODUCT OVERVIEW

The OptiX OSN 500 is new-generation optical transmission equipment, which is developed for the access layer.

Appearance of the OptiX OSN 500:

Slot layout:

The lower slot is an ISU slot, and the upper two slots are extended slots. The ISU slot houses a functional board integrating the SCC unit, cross-connect unit, clock unit, tributary unit, line unit, and data transparent transmission unit. The ISU board is available in multiple types depending on the functions and access capacity provided by the OptiX OSN 500. The extended slots support the line unit, tributary unit, and data unit.

The OptiX OSN 500 supports the higher-order full cross-connections of 21.25 Gbit/s or lower-order full cross-connections of 5 Gbit/s. The cross-connect unit of the OptiX OSN 500 is integrated on the ISU board. The cross-connect unit is a mandatory functional unit and provides the following functions: 

•Service grooming function of the ADM equipment 

•Higher-order full cross-connections of 21.25 Gbit/s or lower-order full cross-connections of 5 Gbit/s

Maximum Access Capability

The OptiX OSN 500 can access services through various interfaces.

Ports

The OptiX OSN 500 provides service interfaces, network management (NM) interfaces, and auxiliary interfaces.

Networking Capability

The OptiX OSN 500 can form multiple network topologies such as the ring network and chain network. The OptiX OSN 500 supports separate and combined configuration of the following types of NEs: terminal multiplexer (TM) and add/drop multiplexer (ADM). The OptiX OSN 500 can form a chain or ring network by using the STM-1/STM-4 optical interfaces. When the OptiX OSN 500 functions as the access equipment, it can network with Huawei Metro and OSN equipment series. The OptiX OSN 500 can also network with third-party equipment.

DCN Features

The OptiX OSN 500 supports three communication protocols and transparent transmission of the DCC through the external clock interface, thus implementing the data communication network (DCN). 

Any of the following three methods can be adopted for the OptiX OSN 500 to transparently transmit the operation, administration and maintenance (OAM) information on the third-party equipment, or for the third-party equipment to transparently transmit the OAM information on the OptiX OSN 500: 

l HWECC 

l IP over DCC 

l OSI over DCC 

When the DCC bytes of the third-party equipment cannot be used for transmitting the OAM information on the OptiX OSN 500, the external clock interface of the OptiX OSN 500 can be used to transmit the OAM information.

Ethernet Features

The OptiX OSN 500 provides layered protection for the Ethernet services, and supports all the protection at the SDH layer and the Ethernet service layer. The OptiX OSN 500 supports Ethernet private line (EPL) services, Ethernet virtual private line (EVPL) services, Ethernet private LAN (EPLAN) services, and Ethernet virtual private LAN (EVPLAN) services. In addition, the OptiX OSN 500 supports various Ethernet protection, operating, and maintenance functions.

Various Types of Power Inputs

The OptiX OSN 500 supports various types of power inputs. 

The types of power inputs supported by the OptiX OSN 500 are: 

l –48 V/–60 V DC power 

l 110 V/220 V AC power
