15216-EDFA3 - Cisco METRO EDFA MID STGE ACCESS VAR GAIN 17 DBM UNDER CISCO WARRANTY SMARTNETABLE

An erbium-doped fiber amplifier, or EDFA, is an optical repeater that amplifies an optical laser beam directly, bypassing opto-electronic and electro-optical (O/E and E/O) conversion. The EDFA uses a short length of optical fiber that has been treated or “doped” with the element erbium. When the laser that carries the signal causes the signal to pass through this fiber, energy is applied to boost, or amplify, the level of the signal.

The Cisco ONS 15216 EDFA3 is an erbium-doped fiber amplifier designed for optical signal amplification within network infrastructure. This device functions as an optical repeater, directly amplifying an optical laser beam without requiring opto-electronic and electro-optical conversions. It utilizes a short length of optical fiber doped with erbium, through which the signal-carrying laser passes, receiving an energy boost to amplify its level. This process helps maintain signal integrity over extended distances in optical networks. The 15216-EDFA3 is suitable for IT professionals and network engineers managing optical transport systems where signal degradation due to distance is a concern. It addresses the problem of signal loss by providing direct optical amplification, streamlining network design by eliminating the need for O/E and E/O conversions at amplification points. This unit is a Metro EDFA with Mid Stage Access and Variable Gain up to 17 dBm.
