Tunable Optical Filter

Supporting 100 and 50GHz channel spacing DWDM systems in the C or L-bands, the Optical Tunable Filter enables individual channels to be selected under remote computer control.

Reconfigurable Optical Add/Drop Multiplexer

Using the same micro-optics design and athermal packaging technology, the Tunable Optical Add/Drop Multiplexer enables individual channels to be added or dropped. Cascading two devices provides full add and drop functionality.

Tunable Edge Filter

Using a low-pass or high-pass thin film interference filter and micro-optics actuators, the Tunable Edge Filter enables fast and easily controlled cut-off wavelength across the C and L bands. Cascading a low-pass with a high-pass filter enables tuning centre wavelength and bandwidth for a bandpass or bandstop filter.

Optical Performance Monitor

Using interference thin-film filters, a full scan of the C & L bands measures wavelength and power levels for DWDM channels

Inline Wavelength Power Monitor (IOWPM)

Lightwaves2020 Inc.’s Compact Inline Optical Wavelength and Power Monitor is a physical layer inline monitoring device which enables real time monitoring and tracking of the optical wavelength and power of an optical system and/or a network link. Based on our proprietary thin film technologies and vertical integration capabilities, the monitor is designed to have unique remote functions as well. It can be used to monitor, report and manage the optical data and alarms through the 802.3 Ethernet LAN.

Inline Optical Power Monitor (IOPM)

Lightwaves2020’s Inline Optical Power Monitor (IOPM) combines a compact single-channel Miniature Tap Optical Power Monitor (MOPM) with state-of-the-art control electronics and firmware within a small-form factor package to offer real-time monitoring and remote measurement of optical power on the light path, and provide collection of optical power variation information and trigger the alarm when the optical power level is outside a certain range. The real-time monitoring information can be accessed via RS232 interface or directly via an analog voltage. The monitor includes a digital LCD display.

Covering the operating wavelength range from 1525 to 1615nm, the IOPM offers excellent optical and electrical performance, including low dark current, low excess insertion loss, low wavelength and polarisation dependence, wide dynamic optical power range and ultra flat power response over a wide wavelength range.

The IOPM simplifies the demanding applications in optical systems and networks. In addition to be used in telecommunication network monitoring, this intelligent Mini Inline Optical Power Monitor can be used in special networks, such as security, banking, transportation, and oil lines, etc.
