As the speed of optical networks grow and as switching functions are increasingly pushed into the optical layer, demands for Dynamic Signal Control (DSC) technology become enormous. We have determined that DSC mainly includes the following technologies:
Dynamic polarization control
Dynamic power control
Dynamic timing and phase control
Dynamic dispersion control
DSC technology plays a critical role in the deployment of next-generation optical networks because of its capability of restoring the integrity of optical signals when they travel at high bit rates (over 10 Gb/s) and/or for long distances (over 300 kilometers). DSC based products can also dynamically conduct gain flattening, add/drop wavelengths and control the timing of optical transmission in order to enable all-optical networks. As of today, very few products in the DSC category are available to fulfill the needs of network growth. General Photonics is positioned to be a leader in DSC technology by providing an array of key dynamic signal control products. |

| Electron multipliers (EMT) are used for the detection and measurement of electrons, charged particles such as ions, VUV radiation and soft X-rays. Hamamatsu electron multipliers have high gain and low noise, making them suitable for the detection of very small or low energy particles. An EMT has CuBeO dynodes for producing gain via secondary emission. The dynodes are connected by a built-in voltage divider (1M ohm per stage) and are supplied in an evacuated glass industrial bulb. The first dynode can be replaced by a photocathode of CsI or KBr for use in VUV photometry. Mcps (MCP) can also be used as electron multipliers. EMTs are used in applications such as mass spectroscopy, field ion microscopy, electron or VUV spectroscopy, Auger spectroscopy, AES and ESCA. |

Fiber Bragg gratings (FBGs) have quickly established themselves as one of the key enabling technologies behind the 'DWDM Revolution'. EDFA gain-equalising professional filters, WDMs and add-drop multiplexers, created as periodic variations in the refractive index of the core of the fiber itself, have all played their part in delivering almost unlimited bandwidth - and in accelerating the transition of the entire telecommunications industry from a digital electronic to a digital photonic world.
FBGs can also be used in the fabrication of optical strain and temperature sensors manufacturers, with quasi-distributed measurements possible using gratings written sequentially into a continuous length of fiber. |

| These new fiber-optic professional amplifiers for mounting on Din rails (DIN/EN 50022) are distinctive thanks to their narrow housing width of just 10 mm, which permits their optimum stacking in large numbers. The devices are further distinguished by their long sensing range, which extends from 0 to > 200 mm, depending on the optical fibers used (no blind zone). The operating distance can be adjusted between 20 and 200 mm. Adjustment is effected by means of a 12-turn potentiometer with an illuminated professional scale. The devices are simple to operate and feature an excellent switch-point stability as well as a high switching frequency of 1.5 kHz. The switching output can be set to either light- or dark-On directly on the device. Besides this, these fiber-optic devices have an aditional excess light output and are largely insensitive to environmental influences (IP 64). They are available with both red light and blue light (sensing range 0 to > 100 mm, adjustable from 20 to 100 mm). In addition, the Contrinex range also includes high-performance devices with sensitivity adjustment by teach-in. |

A variety of casings can be offered for piezosystem jena switches. Depending on customer requirements, plug-in casings are available as well as screw slot casings and special custom size rack mount casings.
The casing not only protects the mounted fiber, it’s also the basis for easy integration of this part into your existing system.
Optical Interface
All fiber switches come standard with 1m output optical fibers and assembled connectors suppliers per customer request. Also, switches with plug in connectors (bulk head) are available. In this case, the customer can select his socket type. In each case, the customer is free to select an additional outside cable length according to his requirements.
PC connection
The switches can be controlled by TTL signal (for type 1x1 up to 1x2 channel configurations) and BCD Code (via parallel port) for 1x3 up to 1x81 channel configurations. Controlling Demo-Software comes with every switch.
Power dispenser
The operating voltage for the switch configuration 1x1 and 1x2 is 7-12 V DC or 7-9 V AC. The multiplexer with a channel configuration of 1x3 up to 1x81 needs 5V DC.
piezosystem jena offers wall power supply modules for each switch as an option. |

Optical isolators provide industrial lasers with immunity from back-reflection, thereby improving the signal to noise ratio for laser diode manufacturer based industrial transmitters. This is especially important for high data rate transceivers and transponders, or those devices requiring long span lengths between professional transceiver pairs. All of our isolators are based on dichroic polarizing glass and Faraday rotating crystals for highest performance. These devices are available in a single stage, 1.5 stages, or double stages, with multiple stages providing progressively higher isolation.
LightPath offers isolators in various form factors including: Cylindrical, Surface-Mount, and Sub-Mount. In addition, we manufacture isolators with either an epoxy-free optical path or with a laminated core. The primary benefits of our approach to manufacturing include reduced costs as a result of higher yields, throughput and product consistency as a result of automation. LightPath is capable of delivering a total solution to its OEM customers, from prototype and development contracting through high-volume production. |

When circularly polarized light is reflected, its propagation direction reverses, changing left-circular polarization to right-circular polarization and vice versa. Therefore, the same polarizer that produces circular polarization of the incident beam will block the return beam with an isolation of at least 99.8 percent.
Achieving optical isolation using Meadowlark's circular polarizers requires that a given reflection be specular and that there is no medium intervening between the reflector and optical insulation to cause significant depolarization or polarization modification.
