Máy Phát Quang 1550nm FWT-1550ES

FWT-1550ES series Externally Modulated Optical Transmitter adopts narrow line width, low noise and continuous wave DFB laser as light source and adopts low cost single-output LiNbO3 external modulator that is especially designed by JDSU to modulate signal, which reduce the cost of transmitter largely.

Based on a series of characterized optimization and technical innovation, FWT-1550ES series Externally Modulated Optical  can reach excellent index with flatness ≤0.75dB in bandwidth of 47~862MHz, SBS:13-16-18dBm, point to point>50Km,（0dBmReceiving）CSO≤-65dB, CTB≤-65dB, CNR≥52dB.

The whole unit is equipped with perfect RS232 communication interface, SNMP network management, 1+1 back-up power supply, and casing temperature auto-control.all the optical port for FWT-1550ES Series Externally Modulated Optical  can be installed in the front panel (the back panel is also available if needed).

FEATURES:

◆ High performance: no laser chirp, low dispersion distortion, high extinction ratio, with excellent characteristic within 40~862MHz in-band.

◆ Narrow bandwidth（Typ.=1MHz), low noise and DFB continuous wave laser.

◆The operating bandwidth is up to 47~862MHz.

◆ High index: unique innovation technology, offering excellent CNR, CTB and CSO.

◆ SBS:13-16-18dBm, point to point>50Km optical transmission.

◆ AGC/MGC mode is optional at spot, OMI can be optimized at spot.

◆ Optional 1+1 back-up power supply.
