Product List
1. Micro MBC
i. Micro MBC-1 (one-channel
device) These products were developed for telecommunication applications, and other applications involving LiNbO3 E/O-amplitude modulators. The modulator bias controller locks LiNbO3 to the desired working points, such as Null, Peak, Quad (Linear) points. Mini-MBC-1 is developed for analogue applications. Micro-MBCs are for digital applications. Micro-MBC has one channel or two-channel model for controlling one modulator, or controlling two modulators simultaneously. More 2. Mini MBC -1
This is a full function LN modulator bias controller designed for analog applications. It can lock modulator to Peak, Null, Quad+, Quad-. The working point can be selected on the board by changing jumper positions. It has access to Photo-detector integrated in the modulator. Mini-MBC-1B is designed for high extinction ratio operation. Its small pilot tone does not interfere the system, can reach 50dB extinction ratio as long as the modulator allows. It also has user Priority-selection for locking the modulator at negative bias or positive bias first. More 3. Mini MBC-3 , a tunable modulator bias controller
This is a full function LN modulator bias controller designed for analog applications. The tune-ability is an important feature of this device. It not only can lock modulator to Peak, Null, Quad+, Quad-, also can lock the modulator to other positions. The working point can be selected on the board by changing jumper positions. It has access to Photo-detector integrated in the modulator. It has a remote control port for user to tune the working point remotely.More 4. Mini MBC-4 , a Dual bias-port, high-extinction ratio modulator bias controller
This is a single Null mode LN modulator bias controller designed for dual bias-port modulator locking with very high extinction ratio, typically to 52dB.More 5. DPMZ MBCs for DQPSK or SSB applications
0050-DPMZ MBC for SSB Applications
0050C-DeskTop DPMZ MBC for SSB Applications
0053-DPMZ MBC for DQPSK Applications
0053C-Desktop DPMZ MBC for DQPSK Applications
The Dual-Parallel MZ (DPMZ) modulator bias controller is a device specially designed to control the bias positions for dual-parallel MZ modulators used for DQPSK applications. The DPMZ MBC will lock the first and second modulator to Null and the third position to quad. The slope is selectable on board. The unit provides both differential bias voltage outputs and single-side voltage outputs. More
0054D/S DP-QPSK MBC for DQPSK Applications (80Gbit applicaitons)
The DP-QPSK modulator bias controller is a device specially designed to control the bias positions for DP QPSK modulators used for DQPSK applications. Each DP-QPSK modulator contains 6 modulators. The 0054D/S DP-QPSK MBC will lock the first and second modulator of each DP-QPSK modulat to Null and each third modulator to quad. The slope is selectable on board. 0054D is for differential bias outputs, 0054S is for single-ended bias outputs More
0056DQ DP-MZ MBC for DQPSK/QAM Applications
The 0056 DP-MZ modulator bias controller is a device specially designed to control the bias positions of a DP-MZ modulator for DQPSK or QAM applications. Each DP-MZ modulator contains 3 modulators. The user can select DQPSK or QAM mode. More
0056C DeskTop Multi-function MBC for SSB/DQPSK/QAM and other Applications
The 0056C Multi-funciton modulator bias controller is a device specially designed to control the bias positions of a DP-MZ modulator for SSB, DQPSK or QAM applications. The user can also change working points and slope for each modulator for their own applications.More
6. Chip-MBC Chip-MBC is a small size, low cost, single function modulator bias controller for digital applications. It can be configured in factory to Peak, Null, Quad+ and Quad- mode. Its user friendly interface makes it easier to mount it to their system, there is no evaboard required. More

It locks the bias of the device to desired reference point without using a dithering signal. It has many applications, such as MZ Modulator Bias Control or Fabry-Perot filter control. It features high accuracy, high dynamic range. The locking slope can be switched with a sliding switch on the board.More
8. Precision Ditherless Bias Controller This Precision Ditherless Bias controller is an OEM version stand-alone bias control feedback loop. It uses dither mode to bring the modulator to quad position with user selected slop,then the unit will enter ditherless mode to continue locking at the selected quad position. It has remote control port, and the local manual tuning mode. With selection, it can also lock the bias of the device to desired reference point at ditherless mode. It has many applications, such as MZ Modulator Bias Control or Fabry-Perot filter control. It features high accuracy, high dynamic range. The locking slope can be selected on the board.More
9. DFB Laser Temperature Controller and Current Driver This DFB Laser Temperature controller and Current Driver is designed for both floating and grounding DFB Lasers. It has laser mount on the board, easy to mount.More
10. Super Fast EDFA This Super Fast EDFA has very fast transient suppression. The transient suppression time is less than 100 ns when turn the system from dark to one channel. It is designed for burst control and DWDM system.
11. OSNR Generator This Optical Signal Noise Ratio Generator is a useful tool for characterize communication system. It consists ASE source, EDFA, and an narrow band tunable filter. The OSNR can be adjusted by a tunable attenuator More
12. Optical Fiber Notch Filter (two-tap FIR filter) This optical fiber notch filter is built with optical fiber technologies. It has high frequency bandwidth, deep filtering depth, low loss and compact size. One of the important features is that its insertion loss is independent on the storage ring size. It is particularly useful for synchrotron storage rings to filter out the revolution frequency in the beam signal.
13. Single-Shot Capture and Regenerator This instrument will work together with a sampling oscilloscope as a high-bandwidth real-time oscilloscope with frequency range of 20 GHz. Tests have been done with High-energy charged particle accelerator beams and with an impulse signal generator. The instrument utilizes fiber-optics and electronics, with unique state of art technology to measure single-shot, very short multi-channel signals. More a) Pictures
