Multi-Wavelength Meter
86122C
With an absolute wavelength accuracy of 0.2 ppm and 0.15 ppm differential accuracy, the new Keysight 86122C Multi-Wavelength Meter belongs in the top class of wavelength meters available for optical communication testing. Its wavelength range of 1270 to 1650 nm covers all fiber-to-the-home, metro and long-haul transmission systems. The instrument can measure the spectra of up to 1,000 laser lines at once, which is more than sufficient for fully populated dense-wavelength-division multiplexed systems (DWDM).

Band DWDM EDFA
MSA Module C
Amonics now packages one of its most popular product lines, C-band DWDM Erbium-doped Fiber Amplifiers (EDFAs), into standard MSA size. The same reliable, stable and durable EDFAs are thus readily available for system integration of a wider range of applications. The devices provides the usual alarms and status indicators, with an integrated RS232 computer interface for easy control, diagnostic functions and data acquisition. This MSA series will be expanded to cover EDFAs of different specifications in our product range in order to meet the growing demands.

CATV Separate Raman Amplifier
RFA4000
Hangzhou Huatai Optic Tech. Co., Ltd.
1. Erbium-doped Fiber Amplifier, due to the multiple cascades and the accumulation of noise caused by spontaneous emission, will reduce the system CNR greatly and thus it will limit the transmission capacity and distance of the system. Raman Amplifier is a newly designed fiber amplifier based on Stimulated Raman Scattering (SRS) effect. Raman amplifier is considered as the core technology of new generation DWDM fiber over-long communication. Compared with Erbium-Doped Fiber Amplifier, Raman amplifier has the advantage of low Noise Figure (NF), wider gain bandwidth, flexible gain spectral region and stable temperature. It is the only device that can operate in 1300~1600 nm.

Fiber Identifier
OFI-20A
OFI-20A can detect optical signal presence, type and direction anywhere on fibers during optical network deployment, maintenance and troubleshooting. With non-destructive macro-bend detection technology, it introduces no damage to tested fiber or interference to the service on fiber. OFI-20A is able to identify wide-spectrum signals (such as signals in CATV system) and can be used in SONET/SDH & DWDM systems tests.

Multiplexers (MUX)
WDM
It is highly desirable to reduce the number of cables required to communicate between spaces on Navy ships due to increased weight, cost and maintenance concerns. To reduce weight and expense, copper-based NTDS parallel and serial type cables can be converted to fiber optic and multiplexed using Wavelength Division Multiplexing (WDM) technology. WDM technology allows for multiple fiber optic wavelengths to be combined in a single fiber and then separated back to individual fibers at the distant end. Using Coarse WDM (CWDM) which utilizes wavelengths 20nm apart ranging from 1271 nm to 1611 nm, provides for up to 18 optical wavelengths to be combined into a single fiber. Optionally Dense WDM (DWDM) can be used allowing for up to 160 optical wavelengths.
