Olycom OLP optical fiber line protection system

Parameter

Front Panel

Description

1) Optical interface description: The flange on the equipment panel is the signal interface.

2) When removing the optical fiber connection cable, cover it with a dust cap to prevent hard objects, dust or other dirt from touching, damaging and contaminating the optical output port.

3) LCD display: displays input and output optical power and other related information.

4) ▲——Up key; ▼——Down key; Enter——OK key; Esc——Cancel key.

5) RST: Supports hardware reset and hardware initialization by operating buttons.

Rear Panel

Description

1) The power supply (PIU) slot is on the back of the device, supporting AC (APU)/DC (DPU) optional, and 1+1 hot backup of the power supply.

2) Indicator light: PWR: on: normal power supply; off: no power supply or abnormality.

3) RJ45 Ethernet interface, RS-232 serial port: communication interface for device monitoring data information.

Key Features

1. Shorten communication interruption time, improve maintenance efficiency, and automatically restore communication in a very short time
2. Reduce various losses caused by line failures
3. Increase the reliability of the transmission network and improve the service quality of operators
4. Arbitrary scheduling of active and backup work routes (line maintenance, cutover scheduling) while ensuring no business interruption
5. Support screen display, real-time monitoring of main and backup optical fiber optical power, and transparent transmission
6. Support remote and short-range control of the entire system to facilitate equipment management and maintenance.

OLP: 1+1

Settings

1.Working mode setting

The device provides two working modes: manual mode and automatic mode.

The manual mode is used for device commissioning and forced switching.

(1) Select automatic and manual through network management;

(2) Select through the device button, long press the device panel button until the Auto light goes out (working in manual) or lights up (working in automatic)

After the operator completes the operation, the equipment should be placed in automatic working mode, otherwise protection failure accidents may occur.

Note: The device supports automatically returning from manual mode to automatic mode, and the return time is 5 minutes by factory default setting.

2.Main route settings

The device provides main route settings. Customers can select R1 or R2 as the main route according to needs; the factory default is R1 as the main route

3.Work route settings

The factory default R1 is the primary working route (Pri), and R2 is the backup working route (Sec).

When the device is in automatic working mode, the device will automatically select a working route based on line conditions:

(1) When only one route is available: work on the channel corresponding to the available route;

(2) When both routes are available: the route corresponding to the route that works first in time (if working on the backup channel, the device will automatically switch back to the main channel after 5 minutes, provided that the device is started the switchback function).

When selecting a route manually, set the device to manual mode and set the working route through the panel buttons or network management

4.Switch threshold power value setting

The initial switching threshold power value of the device is -30dBm. The user can make corresponding settings according to the type of device and the actual situation of the other party's line.

Basic principle: The switching threshold power value is slightly greater than the minimum received power value of the optical transmission equipment, and the difference is 0.5~1dB. (The minimum received power value is subject to ensuring normal transmission of the entire system service).

5.Switchback mode settings

Definition of switchback: In automatic mode, the device switches from the backup state to the main state. Can be set to "automatic switchback" or "automatic no switchback". In the "automatic non-switchback" mode, even if the switchback conditions are met (both the primary and backup routes are normal), the backup route will not be automatically switched to the main route.

6.Switchback delay setting

When the device is in the "automatic switchback" mode, the optical path is in the backup state, and the device is working in the automatic mode, the device will perform light detection on the main and backup paths in real time. If it detects that the optical power of the main and backup paths is within M time (0~999 minutes), the device will automatically switch back to the main road (Pri) state.
