ROC3-EDFA11725 - Optical EDFA Booster C-Band, 17dBm power, 25dB gain card for ROC3 Chassis, managed

Product description

ROC3-EDFA cards are perfect complements for the ROC3 optical transport platform. Erbium Doped Fiber Amplifiers (EDFA) are designed to increase fiber optic signal over single-mode fibers and they are built for the C-Band, which is centered around the 1550nm wavelength. Thus, EDFA amplifiers are perfectly suited for DWDM applications. An EDFA amplifier is defined by two major values: the total power of the EDFA card (measured in dBm) and the maximum gain offered (measured in dB). The ROC3-EDFA cards are available as Boosters, In-line Amplifiers or Pre-Amplifiers: and they are placed either at launch (Boosters) to improve the strength of the Tx lasers, midspan (In-line Amplifiers) to re-amplify signal or finally at Rx end (Pre-amplifiers) to lift the very low signal at a readable level for the active optical equipment. ROC3 EDFA cards all have AGC and APC functions: Automatic Gain Control and Automatic Power Control to provide smooth and uniform amplification across the wavelengths in use. The ROC3-EDFA is designed to amplify all light traveling in one direction over a single strand of single-mode fiber.

The ROC3-EDFA cards fit into any of the ROC3 chassis: either ROC-CH04, ROC-CH08 or ROC-CH16 model. There are many other optical cards for the ROC3 platform, all can be managed via ROC3-NMC card. Among the optical cards available for ROC3 platform we can find transponders for 100G, 25G, 10G and even lower speeds such as Gigabit or Fast Ethernet, CWDM and DWDM mux demux cards going as far as 40 channels in an AAWG configuration (ROC3-DWDM-AAWG) or ROC3-OLPS35 1:1 optical protection cards. Many other function cards, such as DCM compensation modules, Optical Protection, Optical Switches, Variable Attenuators or FWDM cards are available for the ROC3 chassis. Platform is dimensioned for 19" rack mounting and has 23" rack adapting brackets available on demand. 

The ROC3 chassis series provide redundant power supply system with "hot swap" feature, to provide continuous smooth operation of the units installed. The ROC3-EDFA cards are also hot-swappable, settings are stored in the ROC3-NMC management card. In case of a protection card malfunction, card can be removed and a newly inserted card will automatically be programmed by the NMC card with previously saved configuration, so the chassis keeps running unimpeded and without any programming effort from technician to recommission the new card.
