Product description

Software

The OM22 Calibration Software (HRC) software are used in laboratory or industrial facilities to calibrate coherent ﬁber optic receivers. This product is primarily targeted for calibrating polarization-diverse, phase-diverse receivers that are linear or can be set in a linear mode.

The end result is a transfer matrix, measured at a particular heterodyne frequency over a speciﬁed wavelength range, that describes the optical-to-electrical transfer function of the analog portion of the re ceiver. The transfer matrix is

used to compute critical receiver speciﬁcations such as quadrature phase

then angle, polarization cross-talk, and path gains. This information can be used for quantitative evaluation of the receiver, or to provide calibrated optical ﬁeld measurements when used with the OM4000 signal analysis software.

Optical communications signals are the combination of a continuous laser ﬁeld (cw) and a modulation ﬁeld that carries the data. In the case of polarization multiplexed signals, there can be as many as two independent lasers and modulators that are polarization-multiplexed together.

, network, and hardware setup

10 Coherent Receiver Calibration Source and associated Hybrid

The OM4000 signal processing software is designed to extract the cw and modulation for each polarization from which data and signal-quality metrics may be extracted. Since the software extracts ﬁelds, not just da ta, it is necessary to have independent measurements of the receiver properties so that the effect of the receiver may be removed. This process consists of a low-frequency measurement of the linear OE transfer matrix relating the input ﬁeld vector, E, to the output voltages, V, and a separate frequency response measurement. The OM2210 can measure the linear OE transfer matrix, H, at frequencies well within the oscilloscope bandwidth.

V=[H]E

OM2210 Calibration Source 1

Getting started

This process ca well as receivers with automatic gain control (AGC) such as commercial coherent receivers. The AGC must be turned off during the calibration so that the software can measure the linear portion of the transfer function. The matrix can then be normalized to simulate the AGC operation.

The calibration software extracts the hybrid matrix, H, by applying a heterodyne signal with different polarizations and then measuring the resulting sine wave outputs on the oscilloscope while separately monitoring the power. Proprietary calculati impairments, heterodyne phase ﬂuctuations, and channel skews.

DHCP-enabled network

Before using LRCP, you must make sure that IP addresses of the OM series instruments are s following sections describe how to set the OM instrument IP addresses for use on DHCP and non-DHCP networks.

The OM instrument is set with automatic IP assignment (DHCP) enabled by default. Therefore you do not need to speciﬁcally set the instrument IP address, as the DHCP server a utomatically assigns an IP address during instrument power-on.

The following procedure describes how to use LRCP software to verify connectivity of the OM instrument to a DHCP-enabled network.

Prerequisite: OM instrument, and a controller PC (with LRCP software installed), both connected to the same DHCP-enabled network.

1. Connect the OM instrument to the DHCP-enabled network.

2. Power on the OM instrument with the rear power switch (set to 1). The

instrument queries the DHCP server to obtain an IP address. Wait until the front panel Power button light turns off.

Work with your network administrator to obtain a unique IP address for each device. Your network administrator may need the MAC addresses of the computer, oscilloscope, and OM instrument. The MAC address for the OM instrument is located on the rear panel label.

NOTE. Make sure to record the IP addresses used for each OM instrument, or

ttach a label with the new IP address to the instrument.

If you are setting up a new isolated network just for controlling OM and associated instruments, Tektronix recommends using the OM instrument default IP subnet address of 172.17.200.XXX, where XXX is any number between 0 and 255. Use the operating systems of the oscilloscope and computer to set their IP addresses.

NOTE. If you need to change the default IP address of more than one OM

instrument, you must connect each instrument separately to change the IP address.

There are two ways to change the IP address of an OM series instrument:

Finally, the button will turn bright green when the controller and lasers are ready for action.

NOTE. The button color scheme of bright green meaning running or active,

grey meaning off line or inactive and red indicating a warning or error state is consistent throughout the application.

Once the controller tab is active and the laser panels have populated with the corresponding laser information the user is free to put change the laser settings and/or turn the lasers on. When the controller is ﬁrst turned on the current state of the hardware is read to pre-populate the laser panel. Any time you exit application, the current state of the lasers is preserved, including the emission state.

The Laser Receiver Control Panel (LRCP) user interface

If the lasers ar laser usage type needs to be set using the dialog on the lower right corner of each laser panel. The OUI uses the setting to determine from which laser frequency information is retrieved. A usage type can only be selected once between all of the controllers but you can have one usage type on one controller and another usage type on a second controller.

Once laser emission is “On” the channel 1 and grid spacing settings become read only and cavity lock becomes editable. Also the power goes from “off” to the actual once per second.

Channel: Type a number or use the up/down arrows to choose a channel. The range of channels available will depend on the type of laser, the First Frequency, and the Grid. The ﬁner the Grid, the more channels are available for a given laser. The channel range is indicated next to the word Channel. The laser channel can also be set by entering a wavelength in the text box to

he right of the channel entry. The laser will tune to the nearest grid frequency.

Cavity Lock: The Intel/Emcore ITLA laser that is included in the OM4000 instrument has the ability to toggle its channel lock function. Ordinarily, Cavity Lock should be checked so that the laser is able to tune and lock on to its frequency reference. However, once tuning is complete and the laser has stabilized, this box can be unc hecked to turn off the frequency dither needed for locking the laser to its reference. The laser can hold its frequency for days without the beneﬁt of the frequency dither. The OM4000 software will work equally well with the Cavity Lock dither on or off.

Power: The allowed power range for the laser. Type or use the up/down arrows to choose the desired laser power level.

choices. Use 0.01 THz if tuning to arbitrary (non-ITU-grid) frequencies. Using this grid plus Fine Tune, any frequency in the laser band is accessible.

Laser Electrical Power: This should normally be checked. Unchecking this box turns off electrical power to the laser module. This should only be needed to reset the laser to its power-on state, or to save electrical power if a particular laser is never used.

Channel setting within the ITLA grid gives the corresponding frequency (in THz) and wavelength (in nm). Power is set within the range allowed by the laser. It is best to set the Signal and Reference lasers to within 1 GHz of each other. This

If available, ﬁne tuning of the laser is done with the Fine Tune slider bar, and typically works over a range of ±10 GHz from the center frequency of the channel selected.

Certain laser models have a cavity lock feature that increases their frequency accuracy at the expense of dithering the frequency; this feature can be toggled with the Cavity Lock button. Cavity Lock is necessary to tune the laser, but can be unchecked to suppress the dither.

Once the channe l and power for each laser is set, turn on laser emission for each laser by clicking on its Laser Emission button; the emission status is indicated both by the orange background of the button and by the corresponding green LED on the OM4000 instrument front panel.
