GENERAL PHOTONICS CORP. ERM-202-1-98/10-FC Polarization Extinction Ratio (PER) Meter

The General Photonics ERM-202-1-98/10-FC is a single channel polarization extinction ratio (PER) meter specifically designed to measure the PER and power ratio of a device with one polarization maintaining (PM) output, such as a Y-branch fiber gyro IOC, PM coupler (PMC), or polarization beam splitter (PBS), as well as evaluate the performance (output DOP) of depolarizers. An analog electrical PER output for each channel is provided. The instrument possesses a bright OLED display and has 4 different measurement speeds, allowing for high and low speed applications. Axis angle, power ratios, and optical power are automatically measured and displayed on the OLED screen, and can also be stored to be recalled later. The ERM-202 is ideal for PM fiber pigtailing of modulators, waveguides, and laser diodes, as well as for PMC and PBS manufacturing, PM fiber connectorization, depolarizer characterization, PM fiber fusion splicing, PM fiber coil production and quality assurance for fiber gyros.

Broadband Source (BBS)
A Broadband Source is a spectrally large source that emits a signal which contains a continuous range of frequencies with a broad optical bandwidth (usually 100 nm or more). Sometimes called a white light source, there are two different meanings of this term. Visible white light and a source which does not necessarily emit in the visible spectral region.

Coherence
Coherence is the pattern and or relationships of waves due to phase properties.

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and measuring the differences between actual and displayed power levels (in dB), the power flatness is ± half the span between the maximum and the minimum value of all differences.

Singlemode fiber
Singlemode Fiber has a small core, only about 9 microns, and is used for telephony and CATV with laser sources at 1300 and 1550 nm. It can go very long distances at very high speeds. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.
