GENERAL PHOTONICS CORP. ERM-202-2-98/10-FC 2-Ch Polarization Extinction Ratio (PER) Meter

The General Photonics ERM-202-2-98/10-FC is a dual channel polarization extinction ratio (PER) meter specifically designed to simultaneously measure the PER and power ratio of a device with two polarization maintaining (PM) outputs, 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.

Bit Error Ratio (BER)
Bit Error Ratio (BER) is the ratio of errors caused by the number of bits in a data stream that have been altered due to noise, interference, distoriton or bit synchronization errors.

Flatness
Variation of insertion loss on the passband of an optical device.

Polarization Dependent Loss (PDL)
Polarization Dependent Loss is the difference between the maximum and minimum values of loss due to the variation of the polarization states of light propagating through a device. PDL is expressed in decibels. Calculated by; PDL = 10 log10 (Ep/Es), where EP and ES are the measured diffraction efficiencies for P- and S-plane polarized incident light, respectively.

Return Loss (RL)
Return Loss (RL) is the ratio of the incident power to the reflected power expressed in dB. RL = 10log (Pin/Pback)

Wavelength Resolution
Wavelength Resolution is the smallest possible displayed wavelength increment/decrement.
