This 40 channel DWDM EDFA is spectrum flat EDFA for DWDM system.
Comprised of field hardened dense wave division multiplexing (DWDM) optical passives, node-installed EDFAs and optical switches, the VHub allows MSOs to configure hub sites within a compact strand- or pedestal-mounted housing.
PON Booster - This booster EDFA for the 1490nm downstream signal features high output power (up to 15 dBm) while at the same time avoiding signal distortions characteristic of SOA technology.
Raman amplifiers are inferior to EDFA in terms of excitation efficiency.
Although packaged together in a single module, each EDFA within the module can support full WDM operation including transient suppression, and can be controlled completely separately from the other EDFAs in the module.
The Hybrid module consists of a counter-propagating Raman pump unit tightly integrated with a variable gain EDFA, to provide exceptionally low noise figure and excellent gain flatness, two imperative parameters for ultra-long haul and high bit-rate systems.

DCM-optimized EDFA - These amplifiers are optimized for use with zero-latency DCM modules (such as fiber Bragg gratings) at mid-stage, instead of high latency dispersion compensating fiber (DCF).
The system should contain: i) a femtosecond fibre laser with integrated wedge for tuning of the CEO frequency; ii) an EDFA amplifier, a highly non linear fibre for spectral broadening; iii) a non-linear f-2f interferometer based on a fiber-coupled wave-guide, to lock electronics and stabilise the repetition rate and the CEO frequency; and iv) and a suitable user software, PC and display for system control and data acquisition.
The EDFA-OPM's advanced optical monitoring capability meets these market needs by enabling automatic and remote EDFA control.
