EDFA Optical Amplifier module provide multi-function, low noise, Erbium-Doped Fiber Amplifier (EDFA) solutions, The amplifier module can be operated at constant gain (Automatic Gain Control AGC), constant output power (Automatic Power Control, APC). Integrated VOA can be automatically adjusted to achieve smooth gain spectrum. It can amplify the C-Band signal with or w/o middle stage access (MSA), which brings great flexibility for the network application. FUNCTIONï¼? C-band optical signal overall amplification Covering the wavelength range of 1528 ~ 1565nm Support systems to achieve different cross-section radio repeater transmission HIGHTLIGHT: Wide operating wavelength range:1528nm~1565nm Three Optical Amplifier C-Band applications: Booster , In-line, Pre-amplifier Low noise figure: typical: 5dB Excellent gain flatness Multiple operating modes: AGC adjustable Gain APC output is adjustable ACC voltage adjustable Mid-stage access for DCM or OADM Optional OSC channel for remote management MON port, on-line monitoring optical power and OSNR Many model options serve all the traditional amplifier applications in an extended optical link: booster, in-line, and pre-amplifier. A booster amplifier operates at the transmission side of the link. It features high input power, high output power, and medium optical Gain . Boosters are designed to amplify aggregated optical input power for reach extension. An in-line amplifier operates in the middle of an optical link. It features medium to low input power, high output power, high optical Gain , and a low noise figure. In-line amplifiers are designed for optical amplification between two network nodes on the main optical link. A Pre-amplifier operates at the receiving end of an optical link. It features medium to low input power, medium output power, and medium Gain. Pre-amplifiers are designed for optical amplification to compensate for losses in a demultiplexer located near the optical receiver. Some EDFA Models include an additional mid-stage port designed for insertion of a Dispersion Compensation Management (DCM) unit without its inherent insertion loss. The design of these models maximizes the DCM benefits to increase deployment flexibility. New placement options require fewer amplifiers in the link, and they can open the door to applications that were not possible with older technology.

SRT-01 Satellite Phone Indoor Amplifier Device (Inmarsat & Thuraya Suitable) The Satellite Phone Indoor Amplifier Device is a device let your Inmarsat or Thuraya satellite phone can normally use in the room. (used in the boat, vehicle, building etc). Install this device with our special outdoor antenna and omni indoor antenna, making you keep in touch with others freely even in the room, you can call out and receive the incoming call even in the room, no need go out to search the satellite signal and wait for register, and at same time, the device can support up to 100 sets satellite phone communication at same time in the room which cover up to 120 square meters. The basic principle of this device is that the outdoor antenna receives the downlink signal from the satellite (Inmarsat or Thuraya), through high selectivity band-pass filter to well isolate the passband signal, after amplifying by integrative power amplifier, then transferred by indoor antenna, meanwhile, on the way of uplink path, signal of satellite phone in the coverage area is transmitted to the satellite after disposing by uplink amplifying link path by same working mode. For the Inmarsat and Thuraya satellite network system, downlink signal including: satellite and GPS L1 2 signal. The device has Automatic Level control ( ALC )System, automatic control the gain according to the circumstance. Features: -Keep your Satellite phone on communication status even in the room. Avoid miss coming call when you are in the room. And also you no need going outdoor for searching the satellite signal. -The device can suitable for Inmarsat Isatphone Pro, Thuraya SO-2510, SG-2520, Thuraya XT etc models, and also GPS. -Keep your satellite phone can move freely, unlike Fixed Satellite phone which canâ??t move, and also you can freely hand carry your satellite phone when need go out.
