1310nm Polarization Maintaining In-Line Manual Variable Optical Attenuator
1310nm polarization maintaining in-line VOA with 0.5–60 dB attenuation, ≤0.5 dB insertion loss, ≥20 dB extinction ratio, and 500 mW power handling.
1550nm Single Mode In-Line Manual Variable Optical Attenuator
The 1550nm Single Mode In-Line Manual VOA provides adjustable optical attenuation at 1550nm using a screw-driven mechanism for continuous and repeatable control. It is built with SMF-28e single mode fiber and features a maximum insertion loss of ≤0.5 dB, an attenuation range of 0.5–60 dB, and a minimum return loss of ≥50 dB for stable signal performance. The polarization dependent loss is ≤0.1 dB. The all-fiber in-line design requires no external power, allowing direct integration into fiber optic systems. It supports a maximum continuous optical power of 500 mW and is suitable for laboratory testing, optical measurement, and communication system calibration.

What Is an LC Fiber Adapter? Types, Specs & How to Choose
An LC fiber adapter — also called an LC fiber optic coupler or LC mating sleeve — is a passive component that joins two LC connectors end to end so light can pass from one fiber to another with minimal loss. It performs no signal conversion or amplification; its only job is to hold the two connector
What Is a Faraday Mirror (FRM)? Working Principle, Specs & Applications
A Faraday mirror, more precisely a Faraday rotator mirror (FRM), is a fiber-pigtailed passive component that reflects an optical signal while rotating its polarization state by a total of 90 degrees. This non-reciprocal rotation makes the FRM unique: it automatically compensates for the random biref
What Is an In-line Polarizer? How It Works, Specs & Applications
An in-line polarizer is a fiber-pigtailed optical component that transmits light polarized along one axis while strongly attenuating the orthogonal polarization. In fiber optic systems it is used to clean up the polarization state of a signal, define a stable linear polarization reference, and suppr
1x2 DWDM Filter Explained: Single Mode vs PM, 50/100/200GHz Guide
In dense wavelength division multiplexing systems, accurate wavelength selection is critical for adding, dropping, separating, or combining optical channels. A 1x2 DWDM filter is a compact three-port optical device designed for this purpose. It is widely used in DWDM transmission systems, optical am
