Active & Passive Components

PLC Mach-Zender interferometer- Planar lightwave circuits (PLCs) are based on silica waveguide technology and underpin the stability and reliability of the high-performance Mach-Zehnder interferometer.

Stable and reliable Mach-Zehnder interferometer based on silica-based planar lightwave circuit. It is suitable solution for the high-speed DPSK/DQPSK transmission systems.
FEATURE

• Fast optical frequency tracking by thermo-optic effect
• Low PDf (Polarization Dependent Frequency shift)
• Stable against mechanical vibration
• High reliability

APPLICATION

• DPSK/DQPSK demodulation
• Time-domain optical pulse multiplexing

NEL

Mach-Zehnder Interferometer

NEL's optical switches employ Mach-Zehnder interferometers with thermo-optic phase shifters as switching units and include an 8x8 optical matrix switch and an 8-arrayed 2x2 optical switch.

These switches are smaller and use less power than mechanical switches or O/E-SW-EO switches. These switches can be driven by +5V TTL-level voltage.
Main Features:

• Low Loss
• Low Crosstalk
• Low Return Loss
• Small Size
• Excellent Hight Reliability

Thermo-Optic Switches

VMUX and VDMUX consists of PLC based valuable optical attenuator (VOA) and arrayed waveguide grating (AWG).

The VMUX is applicable to point-to-point DWDM network, the add/drop port of wavelength blocker type ROADM node and fixed OADM node.
FEATURE

• Reliable PLC based MUX, DMUX and VOA.
• Automatic power level control.
• Per-channel power monitoring and attenuation control.
• Up to 40-channel.
• I2C electrical interface.

VOA Vmux/Vdemux

The OFR polarization-independent 3-Port-High-Power Circulator, in stainless steel body, is intended for high-power laser applications, as much as 2-5 Watts cw. This compares to around 300 mW for most circulators on the market.

Standard pigtails are 1 meter long, 900 µm, 9/125 SMF 28 fiber. Distal ends are cleaved or optionally terminated with FC/PC connector. Thermal drift of isolation is <0.2 dB/° C. Custom Circulators are possible for special wavelengths and for 4 or more ports. Very high isolation (60 dB) is unique to OFR High Power Circulators.

These are the OCT Series, with dual isolator stages, that produce 60 dB between Ports 3 to 2 and Ports 2 to 1. New OCM high-production model For telecom applications, the new OCM is available in production quantities. The OCM meets international telecom standards. It is limited to 300 mW.

Custom Wavelengths. OC-3 and OCT-3 High-Power Circulators are available at 1310 nm or 1550 nm. Circulators at other wavelengths are built on a custom basis.

Fiber Optic Isolators

With 2 fiber pigtails, three FiberBenches are available. Short, medium and long versions will accommodate 3, 5, and 7 component modules respectively.

Within the Component Stage area on the FiberBench Base is a series of precision holes. Stainless steel dowel pins on the base of the Component Modules lock into these holes. Permanently mounted on all FiberBenches are 2 Port Adapter Plates. It is onto these that the several types of Input/Output Ports are mounted. Variable Delay Line FiberBenches are available.
