VCL-E3 OLTE (Optical Line Transmission VCL-E3 OLTE (Optical Line Transmission Equipment)Equipment)

PRODUCT OVERVIEWPRODUCT OVERVIEW

• VCL, E3 34Mbps (OLTE) Optical Line Transmission Equipment converts and transports a ITU-T compliant standard E3, 34Mbps signal on optical fiber.

• Local and the Remote terminals can be monitored and controlled by a Windows based GUI (Graphical User Interface), from a single location.

• Auto Laser shut off facility.

• Powered by STM-1 grade Class I Laser - by Lucent Technologies.

The VCL, E3-OLTE is available in two configurations:

• With the option of 1+1 Optical Redundancy (Protection Switching).

• Without the option of Optical Redundancy (Protection Switching).


• Single - card implementation.• 1+1 Optical Redundancy (Protection Switching) option.• Standard CCITT (ITU-T) compliant interfaces.• Auto Laser Shut Off facility.• Remote and local terminal monitoring and control through back panel by a

Network Management System.• Optional TCP / IP Remote Access for monitoring alarms and management• Extensive alarms and status indication facility.• Operates on nominal -48V DC input.• Distributed on-board power supply.• Microprocessor controlled with powerful diagnostic facilities for both remote

and local systems.• Powered by STM-1 grade Class I Laser - by Lucent Technologies.• Stored program controlled.• Highly reliable and compact.
