Main Features of OptiX Metro 500

OptiX Metro 500 provides different service access capabilities

depending on the configuration. The maximum access

capability of different services are listed as follow:

Access CapabilityAccess Capability

Service Type Maximum Access Capability

STM-1 2

E1 service 32

T1 service 16

E3/DS3 service 3

Fast Ethernet (FE) service 4

N×64kbit/s service 2

Framed E1 2



OptiX Metro 500 support two different management mode:

OptiX iManager T2000

− OptiX iManager T2000 performs operation,

administration and maintenance (OAM) over the OptiX

Metro 500, realizing service configuration and allocation,

and ensuring reliable running of the network.

Web-LCT

− In the terminal computer with an Explorer of Release 5.0

or above, input the IP address, you can configure

services or query alarms of the OptiX Metro 500, as well

as other NMS operations.

Management ModeManagement Mode



Network ProtectionNetwork Protection

OptiX Metro 500 supports the following network protection:

Path Protection

− Two-fiber unidirectional path protection ring

− Two-fiber bidirectional path protection ring

Linear MSP

− 1+1 linear MSP

− 1:N linear MSP

In addition, the OptiX Metro 500 supports SNCP for the EFT only.



OptiX Metro 500 – Type I

-48V (+24V) DC:

− It provides two DC power supply ports, backing up each other.

− The two internal power modules back up each other.

− Monitor the input voltage and generate alarms for over-voltage or

under-voltage.

220V AC:

− Two internal power modules back up each other.

− Provide alarms upon power module failure.

Power Supply ProtectionPower Supply Protection



OptiX Metro 500 – Type II

It provides the storage battery.

If the 220V AC works normally, the storage battery is charged. If the 220V

AC is powered off, the storage battery starts to provide power for the

equipment.

It provides under-voltage protection for the storage battery.
