The Thor Fiber Externally Modulated Optical Transmitter uses a high-power, low noise, narrow linewidth, continuous broadcast, and a DFB laser. It provides 4~10 way high linearity optical power output. It can connect 4~10 units high-power FTTB EDFA As this product comes standard without an EDFA, each optical port can output up to: CNR≥53.5dB, CTB≥-65dB, CTB≤-65dB. Furthermore you can easily communicate with this device using the RS232 communication interface with SNMP, plus it comes standard with a 1+1 power supply + hot-pluggable back up which helps avoid power damage. The SBS can reach 13 ~ 19dBm adjustable which is perfect for high-power EDFA applications. The External Modulator does not generate CSO distortion, so it can be used with an EDFA to be used a large coverage area and it's ideal for very-long trunk and local networks. Since Thor Fiber uses the best internal components our Optical Transmitters provide excellent APC, ACC and ATC control, while creating an ideal design that vastly improves ventilation and heat-dissipation so we can ensure a long life expectancy and expceptional reliability of the pump laser.
The LCD display is utilized in the vast majority of Thor Products which makes it easy to setup the unit quickly and efficiently, more so to check the status and performance of your externally modulated transmitter. This unit becomes even more tangible for large scale applications with the addition of EDFA's, which Thor Fiber offer's a wide variety of output power options for, to execute difficult and long haul applications to ensure that we can keep your clients connected to any sort of CATV, Phone, and Internet Triple Play Packages your company may offer. The wideband application for use in projects and industrial sized architectures make this a cost effective unit for any budget. Should you have any questions reach out to a Thor Fiber Design Engineer or Sales Executive to learn more about how we can help take your infrastructure to the next level.

Currently, we only have 1550 Transmitters available in 8mW. However, you can pair this with an EDFA (Erbium-Doped Fiber Amplifier) for stronger output power, which is the usual practice.
We have two different types of CATV 1550nm TX's available. The first is the external modulated type, which is used for long-distance transmission
