ANAHEIM, Calif., March 18, 2013 /PRNewswire/ -- OFC/NFOEC 2013, Booth #2627 --
Furukawa Electric Co., Ltd. has developed and started mass production of the
FOL 1437 series of 14xx nm pump source lasers with high output and low power
consumption in the 1420nm – 1460nm range. These are key devices for use in
Raman amplifiers, demand for which is expected to increase as the
telecommunications industry accelerates adoption of ultrahigh-speed
communications at 100 gigabits (Gpbs) per second. By designing in the FOL 1437
pump source laser product line, Raman amplifier manufacturers can immediately
benefit from high output power along with low power consumption, a combination
required to deploy next generation network infrastructure while helping to
reduce operating costs. The FOL 1437 series consumes 20% less electric power
than currently available conventional products.

Presently, global network traffic continues to grow at a phenomenal rate in
both terrestrial and wireless networks. With the smartphone becoming a
ubiquitous tool for both consumers and business users, data traffic from a
number of applications has spurred rapid expansion of wireless backbones to
backhaul mobile network traffic. Other telecom growth factors also include
acceptance and growth of cloud computing, data center connectivity, mass video
distribution to smart devices and social networking. It is now paramount to
address increasing network traffic, first to sustain and second to invest in
evolving the network infrastructure. Therefore, optical amplifiers will
continue to be a critical workhorse in present-day as well as future networks.

Noise performance is a key parameter for ultrahigh-speed optical transmission
at 100 Gbps, a form of transmission that is expected to be introduced
increasingly in the future. Generally Raman amplifier is expected as an
effective solution with excellent noise characteristics. In Raman amplifiers,
a 14xx nm-range laser is used as a pump source. This now requires a shift to
higher output combined with lower power consumption with the aim of continued
performance improvement. For these applications, Furukawa Electric developed
the FOL 1437 pump source laser series. In addition, Furukawa Electric's
pursuit of higher performance, manufacturing strengths and excellent product
quality are other benefits of using this product line in Raman amplifier

The technologies developed in the FOL 1437 series can be extended to other
applications, such as pump source lasers for EDFA (Note 2). Mass production
will commence in the first half of fiscal 2013.

The new product will be exhibited at OFC/NFOEC 2013, scheduled to be held from
March 19 in Anaheim, California, United States.

(Note 1) Raman amplifiers: When a pump light is injected into the fiber, Raman
scattering occurs within a wavelength range that is nearly 100 nanometers
longer than the wavelength of the pump light. When a signal light exists in
the scattered-light area, stimulated emission occurs and multiplies the light.
This can be used as an amplifier. Raman amplifiers are inferior to EDFA in
terms of excitation efficiency. However, their band frequency is broad and can
be increased within an arbitrary wavelength range.

(Note 2) EDFA: Erbium Doped Fiber Amplifier. EDFA is a type of optical
amplifier, characterized by the addition of erbium to the core of optical
fiber. It is often used in wavelength division multiplex (WDM) systems. With a
pump light ranging from 980 nanometers to 1480 nanometers, EDFA is capable of
increasing the wavelength to near 1550 nanometers.
