Features * Wide operating wavelength ranges * High power gain * Low noise figure * Input, output and optional reverse optical power monitoring via incorporated P-I-N photo detectors * High reliability * Wide operating temperature and humidity ranges * Compact packaging * Bellcore GR-1312-CORE qualified and ISO 9001 certified Applications * Metro and access fiber optic transmission systems * Power booster amplifier configuration Product Description Block Diagram General The GM series of EDFAs has been specially designed to provide flexibility by working with a customer's own drive and control circuitry to provide a specific product for use in metro transmission systems as a booster amplifier. Optical This module is based on an erbium-doped fiber amplifier (EDFA), which is pumped with 980 nm diode lasers. Input and output ports are optically isolated to maintain stable operation of the amplifier. An optical splitter on the output port taps a small amount of light onto photodiodes to enable optical power monitoring. Electrical The GM series of EDFA products is equipped with a standard 16-pin male DIP connector. Package The units are housed within very small modules with input and output connections through single-mode fiber pigtails and are fitted as standard with super-polished FC/UPC or FC/APC connectors. Other types of connectors are available on request. V011 1-1 Erbium-Doped Fiber Amplifier (EDFA) - GM Series Absolute Maximum Ratings (in accordance with Bellcore GR-1312-CORE) Parameter Min.

Please read carefully the following safety information prior to handling and installing. The signal output of the pump laser and EDFA is invisible, yet it can be of high power level and therefore can cause damage to the eyes or skin. Please do not look at the fiber cross section directly without protection devices. There are precision optical devices inside the EDFA; therefore extreme care should be taken not to impose excess vibration or shaking. Care should also be taken in handling the pigtail fibers since they are easily broken. There are static sensitive devices inside the EDFA, please make sure proper grounding and electrical power connection. 1-4 Do not attempt to open the EDFA by any unauthorized personnel. Please contact Nanovation technical support for assistance. V011
