In recent years, the excellent performance-price advantage of 1550nm externally modulated optical transmitter technology has come to the fore as optical device production technology has improved and prices have fallen. With 14 years of experience in designing and manufacturing complex fibre optic and electronic circuit equipment, Hangzhou Hengchi Electronic Equipment Co. We have been able to provide consistent and stable service in CATV projects and have received good feedback from many purchasers. Next, we will introduce the 1550nm optical transmitter as an example.
1.Basic introduction to CATV Optical Transmitter
2.What are the detailed features of the CATV Optical Transmitter？
3.What are the advantages of the CATV Optical Transmitter？
1550nm optical transmitters offer high performance, high reliability and excellent performance-to-price ratio for a wide range of applications. Long distance digital and analogue signal communication applications include secondary CATV trunking and distribution networks, CWDM/DWDM systems, fibre optic sensing, security and surveillance systems, etc. The 1550nm external modulated optical transmitter is the core equipment in FFTV network systems and plays an important role.
The 1550nm externally modulated optical transmitter is the core equipment in FFTV network systems and plays an important role. 1550nm externally modulated optical transmitter technology has no laser chatter, low dispersion distortion, large extinction ratio and has excellent characteristics in the range of 47~1000MHz. The external modulator does not produce CSO distortion after reasonable biasing. Amplifier following is available for use in ultra-long trunking and large area coverage in local networks. WDM technology allows transmission of multiple wavelength optical channels over a single fibre. 1550nm fibre is convenient for use with CATV secondary network signal transmission trends and is suitable for use with high power optical amplifiers
Hengchi's CATV optical transmitter is a 1550nm externally modulated optical transmitter that complies with the current international technical standards. The entire light source is a narrow bandwidth (0.65MHz), low noise, continuous wave DFB laser, which helps to reduce the effects of dispersion.
High performance: Externally modulated technology without laser chirp, very low dispersion distortion, large extinction ratio.
Imported dual module RF driver.
Operating bandwidth of 47-1000Mhz.
LCD screen on the front panel to display relevant operating status and fault information.
Automatic laser modulation (MOI) control, AGC and MGC.
Dual power supply, SNMP.
Fully automatic control of housing temperature.
The optional ITU standard wavelength allows users to adjust and set the laser wavelength at the front panel in ±0.05nm steps over a range of ±200GHz (±1.6nm), suitable for WDM systems and network upgrades and expansions.
High metrics: unique and innovative technology providing excellent CNR, CTB, CSO, SBS.
Excellent performance to price ratio.
High performance of Hengchi's CATV optical transmitter. External modulation technology, no laser chatter, low dispersion distortion, high extinction ratio and excellent characteristics in the range 47 to 1000 MHz. It is fully automatic with housing temperature control.
The narrow bandwidth (0.65MHz) of the 1500nm direct modulation CATV optical transmitter device, with low noise and DFB continuous wave lasers, helps to reduce the effects of dispersion.
The equipment can operate with a bandwidth of 47 to 1000MHz (47 to 1080MHz optional). The AGC/MGC mode can be selected on site. omi can be optimised on site.
And it has a perfect RS232 communication interface and advanced FFTV network management function.
We guarantee that all our products serve consistently and highly in optical communication projects for CATV broadband systems. Our expenditure on new production equipment, precision test instruments and quality control systems are always increasing.
