EDFA Optical Amplifier

EDFA Optical Amplifier from Telnet Redes Inteligentes is an interesting unidirectional optical amplifier module based on technology Erbium-doped optical fiber (EDFA). Allows to prolong an optical span. Used in combination with coils of compensation of chromatic dispersion, the EDFA Optical Amplifier can work with transmission rates up to 40G module to extend the 1550nm short-range transponders of the transmission equipment. Used in combination with optical switching card 1+1 allows to make redundant critical long-distance transport paths.


Digital Diagnosis
The EDFA Optical Amplifier has an integrated optical power meter at the output of the optical amplifier that can detect faults in optical amplifier, reporting an alarm to the SNMP controller of the chassis which, in turn, will direct it towards the management console of the optical network. It also reports the available optical power amplifier input.


Low noise figure
With a noise figure of 5dB and a fixed amplification factor of 20dB gain, EDFA technology is a more efficient alternative to SOA amplifiers and is the only one that allows cascade chaining of devices. The card can be factory configured to work in Booster mode or optical preamplifier mode, allowing maximum flexibility in the case that the team can not settle at the midpoint of a fiber optic route.
