Optical Line & Protection

Optical Line Protection

SML - Optical Line Protection

The SML-Optical Line Protection unit is able to provide fibre path redundancy on a channel by channel basis. These units are particularly well suited for protection in fibre data transmission. The solution includes monitoring capabilities for both working and protection paths. The monitoring is available through the SNMP Management unit. In case of a fibre cut in the protecting path, traffic will be switched over to the protecting path in less than 50 ms.

SML-OADM Optical Add-Drop Multiplexer

Optical Add-Drop Multiplexer The SML-OADM Optical Add/Drop Multiplexer takes a single wavelength from a trunk, pulls the signal out, and allows a new signal at the same wavelength to be inserted into the trunk at roughly the same spot. All the other wavelengths pass through the Add/Drop Multiplexer with only a small loss of power (usually < 0.5dB including connectors and adapters). An Optical Add/Drop Multiplexer (OADM) is available allowing a single wavelength to be dropped or added at specific sites in linear Add/Drop topology.
