Passive Components

Choose from our complete line of passive components: filters, attenuators, interleavers, splitters, circulators, isolators, and more.

Bandpass & Edge Filters

Use Coherent Bandpass and Edge Filters to efficiently separate and manipulate signals at closely spaced wavelengths in WDM applications with 200, 100, or even 50 GHz channel spacing.

Free Space Isolators

Use Coherent versatile optics in optical transmitters or tunable lasers in the O- and C-bands to get up to 38 dB of isolation with an epoxy-fee optical path and low insertion loss.

Hybrid Devices

Simplify your fiber optical system while saving space and reducing costs with Coherent hybrid devices that combine multiple optical functions in a single, streamlined package.

Interleavers

Increase spectral efficiency and safely upgrade DWDM capacity with Coherent interleavers configured for 50 to 25 GHz, 100 to 50 GHz, and 200 to 50 GHz channel spacing.

Optical Circulators

Use Coherent unidirectional multi-port couplers to safely separate and manipulate forward (i.e., transmit) and reverse (i.e., receive) signals without crosstalk and with low insertion loss.

Pigtail Isolator

Simplify your application with isolators that are completely packaged and (sC/aPC) fiber-connected, ready for use with any laser requiring protection from back-reflections.

Polarization Independent Isolator Core

Build your own compact isolators for next-generation systems using Coherent optical cores — and get up to 38 dB of isolation with an epoxy-fee optical path and low insertion loss.

Learn More

Polarization Maintaining Couplers

Use Coherent devices to split an input signal into 2 outputs with a precisely set power ratio - from 1:99 to 50:50 - while preserving the linear polarization purity of the signal.

Receptacle Isolators

Specify Coherent versatile isolators in custom receptacles for use in optical transmitters or tunable lasers in the O-, C-, and L-bands or other near-infrared wavelengths.

Learn More

Single Side Isolators

Block back reflections efficiently and completely using Coherent compact optical isolators configured with both fibers ported from the same end of the device.

Learn More

Single Side IWDM

Use Coherent devices immediately before an EDFA to safely and efficiently combine the signal and pump into a single fiber with no undesirable back-reflections or crosstalk.

Tap Photodiodes (Tap PDs)

Enable network traffic monitoring by Integrating Coherent taps within standard transceiver packages (e.g., CFP2) thanks to their small (1.8 or 1.4 mm) diameter format.
