FULLWELL Raman fiber amplifier
1 Product Overview
1.1 Product Overview
Erbium-doped fiber amplifier (EDFA), due to spontaneous emission (ASE) noise, as a result of numerous cascades, the accumulation of spontaneous emission noise, will greatly reduce the SNR of system receiver, thus limits the system capacity and non-relay distance. The new generation of Raman fiber amplifier (FWMA-1550) achieves the amplification of the optical signal by the optical gain generated by the Stimulated Raman scattering (SRS). FRA has a wide gain spectrum, the gain bandwidth can be further broadened by the use of multi-wavelength optical pump. After many years of research and network testing, our company develop and produce the series of FWMA-1550 Raman fiber amplifier, and introduce it to the ultra-long haul optical fiber CATV transmission, specifically in combination with the EDFA applications, the improvement of the indicators of the link is particularly evident, thus get more flat gain spectra and higher optical signal to noise ratio (OSNR).
This series of products adopt 1430nm or 1455nm high linearity, optical isolation, the DFB, thermoelectric cooling DFB laser produced by JDSU, Fitel and other world-renowned semiconductor companies as the pumping source. In the interior of the machine is equipped with the light power export stable circuit and laser Thermoelectric cooling device Temperature stability control circuit to ensure optimal machine performance and long-life laser stability. The microprocessor software monitor the lasers' working state, the Digital Panel (VFD) displays the operating parameters. Once the laser operating parameters deviate from the permissible range set by the software, micro-processing will automatically turn off laser power, red light goes on to warn, digital panel prompts cause of troubles., a detailed report of the device parameters please read "instructions."
1.2.1) High quality:
Because Raman fiber amplifier is distributed structure, we can greatly reduce the optical power into the fiber, so that SBS has been expanded. At the same time the nonlinear distortion indicators will have improved significantly.
1.2.2) Reliability: Reliability: The 19 "1U standard rack, built-in high-performance switching power supply,it can work at 85 265Vac City Network Voltage, As well as an optional DC48V power supply (reservations required); chassis cooling automatic temperature control.
1.2.3) intuitive: The laser is the most expensive machine components, machine equipped with microprocessor monitors the working state of the laser, the panel LCD window displays the operating parameters.
1.2.4) Network type: Select All-piece status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standard, it enable network management monitoring capabilities.
