FAQ

Now we have started offering both S-band PM-TDFA and O-band PM-PDFA. Please contact our sales for details. We also offer PM EDFA in the C- and L-bands.

It depends on the wavelength and pulse properties of your interest. In order to investigate the feasibility, we need the following information: (1) wavelength, (2) average power, (3) repetition rate, (4) pulse duration, and (5) peak power. Please ask us via info@fiberlabs.co.jp with these five pieces of information.

Each of the three packages have their own suitalble areas. Bench Top models are generally useful for experiments and R&D. The instruments can be easily operated by the front panel, and most of our bench top instruments allows you to externally control the device via, e.g., RS-232C and GP-IB. Rack Mountable models are suited for deployment in actual networks. The chassis well fits in the standard EIA rack, allowing easy installation. OEM module type are suited for OEM integration into your own instruments.

The main differences are in: (1) output power, (2), spectral width, (3) wavelength flexibility, and (4) degree of polarization (DOP). In general, output power of fiber ASE sources is bigger than fiber-coupled SLDs, but SLD has a wider spectral width and wavelength flexibility. One critical advantage of fiber ASE sources is that the degree of polarization is inherently small (<5%), so fiber ASE sources are recommended if you need a low DOP value for your application.

You can get a polarized ASE light source simply by using an external polarizer at the output of our fiber ASE sources. The degree of polarization of ASE sources are inherently low, therefore you can still get stable output power and spectrum after the polarizer. If you would like to incorporate a polarizer in the instrument chassis, such customization is certainly possible upon request.

Making a defect-free fluoride fiber is very difficult, even with the current state-of-the-art production technology. After drawing a fluoride fiber, we visually inspect the fiber and remove defects. As a result of the defect removal, the drawn fiber is cut into multiple pieces, and that is the reason that a number of long-length, defect-free fibers is limited.

So if you accpept fluoride fibers provided in multiple pieces, we can offer a better price than that provided in one long-length piece, even though the total length is the same. That would be the choice if you only need a short piece of fiber one time.

FiberLabs' fluoride fibers are used in our optical instruments, specifically for fiber amplifiers and fiber ASE sources. FiberLabs' fluoride fiber amplifiers have been used in actual telecom and datacom networks, and are proven to work over many years.

FiberLabs' fluoride fibers have also been used in many universities, research institutes, and industry customers, mainly for light generation and guidance in the mid-IR. Click here for a list of publications where FiberLabs’ fluoride fibers are referred to.

We sell such items for research purposes only. You cannot use them for commercial purposes, unless a special agreement has been made between you and FiberLabs.

No, we only manufacture fluoride fiber. We distribute silica fibers in Japan, but the activity is as a local reseller.

Yes, FiberLabs' fluoride fibers can be provided in a cable form. The cable can be connectrized and polished, such that you do not need to worry about handling a fluoride fiber.

Note that the fluoride-fiber connector often have some degree of eccentricity, so it is sometimes difficult to get a small loss, simply by connecting to other fibers using an fiber adapter. Free-space optical coupling using lens may be needed.

You can buy directly from us, except for the US and Canada. We may also appoint a local distributor if there is a purchase policy of your company or institute. Please let us know your request when contacting us.

In principle, we ask all customers to make a full payment in advance. We will ship the ordered items after the full payment is confirmed. If you prefer other terms of payment, e.g. pay half in advance, you may appoint a local distributor that allows you other terms of payment.

The warrenty period of FiberLabs products are:

Fiber Amplifier and ASE source: one year after the shipping date,

Fiber-coupled LD and SLD source: 90 days after the shipping date,

Fluoride Fiber: .
