Coset develops fiber optic communication components and
their related application products. The company will supply
optical communication components and their applications
(Pump laser modules , 155Mb/s, 2.5Gb/s, 10Gb/s, SOA, PLC(AWG),
lensed fiber , collimator
packaging) globally.
An optical-amplifier is the main part of optical
telecommunication systems to amplify decreased optical
signals without optical/electrical conversion when it is
transmitted or received through an optical fiber, and a
pump laser module is the part of the optical-amplifier. The
optical amplifier development of erbium-doped fiber
amplifiers (EDFAs) , more than any other technology, has
enabled the proliferation of high bandwidth data
networking. EDFAs are a major advancement in photonics , in
that these devices sharply reduce the need for signal
regeneration , a process by which a photon is converted
into an electron , amplified , then converted back into a
photon. Optical 980-nm pump lasers transfer high levels of
energy to the special fiber, energizing the erbium ions and
boosting the optical signal(s) passing through. EDFAs are
used in the existing WDM (Wavelength division multiplexing)
systems to enable large-capacity transmission.
The company's members are comprised of the key engineers in
the development of module packaging of sub micron fiber
alignment , high coupling efficiency and organic free
vacuum die bonding processes from long experience. Coset
possesses total solutions for volume production , high
coupling efficiency and high reliability fiber optical
components at low costs. Included in the company's core
solutions is a high yield packaging technology, no flux
micro soldering process technology and ultra-precision
optical alignment and laser beam spot welding. In addition
to Coset expertise in these areas, the company offers
process simplification, automation, volume production and
low cost solutions. |
