CATV RF to FO Direct Modulated Optical Transmitter 25km

1550nm directly modulated Optical Transmitter 5dBm

Product Discription

14LTxxxx Optical transmitter with internal modulation series improved from 08LTxxxx,increase
hot plug-in dual power and optical point. Optical signal of signal source can directly enter
into optical interface which not only reduce trouble for connecting optical receiver, but also
main signal enters optical point, program made by user entering RF point. Accordingly,
program by user is modulated to optical signal which can cater to many demands of user.

14LT50xx series 1550nm optical transmitter is mainly applied> 25 km (digital signal 35Km)
distribution network and amplifying. Disadvantage is that it is bad for point to point
transmission,Index of it is not good for 1310nm optical transmitter.

Performance Characteristic

1. Advanced aluminum wiredrawing with good dissipation
2. Advanced RF pre-distortion correction circuit ensure excellent C/N and low
distortion performance.
3. Microprocessor automatically controls output power execute monitoring
optical output power and laser working status.
4. Importing DFB laser in AOI Type from USA
5. LED display in front panel monitoring locally.
6. Hot plug-in dual power supply (same power and also one 220V and the other 48V
backup power supply). It is convenient to change it at any time.
7. Built-in temperature control fan.When temperature is over 27,it operates low
temperature mandatorily to extending service life of laser and fan.
8. Optical AGC range -7~+2dBm, input level keep unchanged
9 .Electricity AGC range 75~95dBuv, input and output level keep unchanged
10. External Optical port and electricity port.ISO SNMP network management system
can execute backup and maintain by customer.
