DCM Inserting type Multi channel Erbium-doped fiber amplifier card

Share

The product is multi-channel EDFA of support dispersion compensation modules insertion, high flattening and high stable output. The product can amplify of before and after by double-pumped, offset the insertion loss dispersion compensation module and has the better transmission performance index than unipolar amplification of high gain. The kernel component of theproduct ishigh availabilitypump laserand high-performance gain flattening filters.
