| Agilent N4375B 20 GHz and 26.5 GHz Single-Mode Lightwave Component Analyzer for 10GbE -LR, OC 192, FCx8, FCx17(16) Data Sheet www..com General Information Agilent's N4375B Lightwave Component Analyzer (LCA) is the instrument of choice to test 10G Ethernet, FCx8, FCx10 and FCx16 electro-optical components, with up to 20 or 26.5 GHz modulation range. Modern optical transmission systems require fast, accurate and repeatable characterization of the core electro-optical components, the transmitter, receiver, and their subcomponents (lasers, modulators and detectors), to guarantee performance with respect to modulation bandwidth, jitter, gain, and distortion of the final transceiver. For frequency dependent responsivity measurements the N4375B is the successor of the industry standard 8703A/B LCAs. With a completely new design of the optical test set and a new RF-switched architecture, together with the latest PNA family of network analyzers, the N4375B guarantees excellent electro-optical measurement performance. In addition a unique new calibration concept significantly reduces time from powering up the LCA until the first calibrated measurement can be made. This increases productivity in R&D and on the manufacturing floor. The fully integrated "turnkey" solution reduces time to market, compared to the time-consuming development of a selfmade setup. By optimizing the electrical and optical design of the N4375B for lowest noise and ripple, the accuracy has been improved by more than a factor of 3 and is now independent of the electrical reflection coefficient of the device under test. It's the excellent accuracy that improves the yield from tests performed with the N4375B, by narrowing margins needed to pass the tested devices. NIST traceability ensures worldwide comparability of test results. The advanced optical design together with temperaturestabilized transmitter and receiver ensures repeatable measurements over days without recalibration. Using the advanced measurement capabilities of the network analyzer, all S-parameter related characteristics of the device under test, like responsivity, ripple, group delay and 3dB-cutoff frequency, can be qualified with the new N4375B Lightwave Component Analyzer from 10 MHz to 20 GHz. Key benefits High absolute and relative accuracy measurements improve the yield of development and production processes. With the excellent accuracy and reproducibility, measurement results can be compared among test locations world wide. High confidence and fast time-to-market with a NISTtraceable turnkey solution. Significantly increased productivity using the fast and easy measurement setup with an unique new calibration process leads to lower cost of test.

Warranty: 1 year warranty is standard for N4375B Lightwave Component Analyzer; Extension to 3 years available. The network analyzer The N4375B comes in two basic versions. The economic line is based on a PNA-L network-analyzer and is available as a 2 port system. The high end version is based on the new PNA-X and offers true balanced measurements, extended www..com optical modulation index (OMI) and is available with 2 or 4 ports. Both versions have the same specifications up to 20 GHz. The PNA-X based LCA is calibrated up to 26.5 GHz. 2 Agilent N4375B Applications In digital photonic transmission systems, the performance is ultimately determined by bit error ratio test (BERT), which parameter describes the performance of the whole system. However it is necessary to design and qualify subcomponents like modulators and receivers, which are analog by nature, with different parameters. Those parameters are core to the overall system performance. These electro-optical components significantly influence the overall performance of the transmission system via the following parameters: 3dB bandwidth of the electro-optical transmission Relative frequency response, quantifying the electrooptical shape of the conversion. Absolute frequency response, relating to the conversion efficiency of signals from the input to the output, or indicating the gain of a receiver. Electrical reflection at the RF port Group delay of the electro-optical transfer funktion Only a careful design of these electro-optical components over a wide modulation signal bandwidth guarantees successful operation in the transmission system. Agilent N4375B Features Turnkey solution In today's highly competitive environment, short time-tomarket with high quality is essential for new products. Instead of developing a home-grown measurement solution which takes a lot of time and is limited in transferability and support, a fully specified and supported solution helps to focus resources on faster development and on optimizing the manufacturing process. In the N4375B all optical and electrical components are carefully selected and matched to each other to minimize noise and ripple in the measurement traces. Together with the temperature stabilized environment of the core components, this improves the repeatability and the accuracy of the overall system. Extended factory calibration data at various optical power levels ensures accurate and reliable measurements that can only be achieved with an integrated solution like the N4375B. Easy calibration An LCA essentially measures the conversion relation between optical and electrical signals. This is why user calibration of such systems can evolve into a time consuming task. With the new calibration process implemented in the N4375B, the tasks that have to be done by the user are reduced to one pure electrical calibration. The calibration with an electrical microwave calibration module is automated and needs only minimal manual interaction. Electro-optical components The frequency response of amplified or unamplified detector diodes, modulators and directly modulated lasers typically depends on various parameters, like bias voltages, optical input power, operating current and ambient temperature. To determine the optimum operating point of these devices, an LCA helps by making a fast characterization of the electrooptic transfer function while optimizing these operating conditions. In parallel the LCA also measures the electrical return loss. In manufacturing it is important to be able to monitor the processes regularly to keep up the throughput and yield. In this case the LCA is the tool of choice to monitor transmission characteristics and absolute responsivity of the manufactured device. The remote control of the N4375B offers another tool to improve the productivity by making automated measurements and analysis of the measured data. Built-in performance verification Sometimes it is necessary to make a quick verification of the validity of the calibration and the performance of the system. The N4375B's unique calibration process allows the user to perform a self-test without external reference devices. This gives full confidence that the system performance is within the user's required uncertainty bands. State-of-the-art remote control Testing the frequency response of electro-optical components under a wide range of parameters, which is often necessary in qualification cycles, is very time consuming. To support the user in minimizing the effort for performing this huge number of tests, all functions of the LCA can be controlled remotely via LAN over the state-of-the-art Microsoft .NET or COM interface. Based on programming examples for VBA with Excel, Agilent VEE and C++, it is very easy for every user to build applications for their requirements. These examples cover applications like integration of complete LCA measurement sequences. Electrical components Electrical components such as amplifiers, filters and transmission lines are used in modern transmission systems and require characterization to ensure optimal performance. Typical measurements are bandwidth, insertion loss or gain, impedance match and group delay. The new switched architecture offers direct access to the electrical outputs and inwww..com puts of the network-analyzers just by selecting electrical- to electrical measurement mode in the LCA user interface. 3 Integrated optical power meter In applications where optical power dependence characterization is needed, the average power meter can be used to set the exact average output power of the LCA transmitter by connecting the LCA optical transmitter output, optionally through an optical attenuator, to the LCA optical receiver input. By adjusting the transmitter output power in the LCA user interface or the optical attenuation, the desired transmitter optical power can be set. In cases where an unexpectedly low responsivity is measured from the device under test, it is very helpful to get a fast indication of the CW optical power that is launched into the LCA receiver. The cause might be a bad connection or a bent fiber in the setup. For this reason too, a measurement of the average optical power at the LCA receiver is very helpful for fast debugging of the test setup. Selectable output power of the transmitter Most PIN diodes and receiver optical subassemblies (ROSA's) need to be characterized at various average optical power levels. In this case it is necessary to set the average input power of the device under test to the desired value. The variable average optical output power of the LCA transmitter offers this feature. Together with an external optical attenuator, this range can be extended to all desired optical power levels. Group delay and length measurements In some applications it is necessary to determine the electrical or optical length of a device. With the internal length calibration of the electro-optical paths with reference to the electrical and optical inputs or outputs, it is possible to determine the length of the device under test Large signal measurements LCA S21 measurements are typically small-signal linear transfer function measurements. If an electro-optical component must be tested under large signal conditions, normal balanced measurements might lead to wrong measurement results. The PNA-X based version of the LCA offers true balanced measurements for differential ports by offering two independent high power RF sources. With this setup the LCA measures the correct S21 transfer function of E/O components, even in the nonlinear regime. To stimulate O/E components like PIN-TIA receivers under optical large signal conditions, the PNA-X based LCA offers a variable optical modulation index up 50%. www..com External optical source input For applications where test of opto-electric devices need to be done at a specific optical wavelength, the N4375B-050 offers an external optical input to the internal modulator where an external tunable laser can be applied. As modulators are polarization sensitive devices, this input is a PMF input to a PMF optical switch to maintain the polarization at the modulator input. 4 Definitions Generally, all specifications are valid at the stated operating and measurement conditions and settings, with uninterrupted line voltage. Explanation of terms Responsivity For electro-optical devices (e.g. modulators ) this describes the ratio of the optical modulated output signal amplitude compared to the RF input amplitude of the device. For opto-electrical devices (e.g. photodiodes) this describes the ratio of at the RF amplitude at the device output to the amplitude of the modulated optical signal input. . Specifications (guaranteed) Describes warranted product performance that is valid under the specified conditions. Specifications include guard bands to account for the expected statistical performance distribution, measurement uncertainties changes in performance due to environmental changes and aging of components. Relative frequency response uncertainty Describes the maximum deviation of the shape of a measured trace from the (unknown) real trace. This specification has strong influence on the accuracy of the 3-dB cut-off frequency determined for the device under test. Typical values (characteristics) Characteristics describe the product performance that is usually met but not guaranteed. Typical values are based on data from a representative set of instruments. Absolute frequency response uncertainty Describes the maximum difference between any amplitude point of the measured trace and the (unknown) real value. This specification is useful to determine the absolute responsivity of the device versus modulation frequency. General characteristics Give additional information for using the instrument. These are general descriptive terms that do not imply a level of performance. Frequency response repeatability Describes the deviation of repeated measurement without changing any parameter or connection relative to the average of this measurements. Minimum measurable frequency response Describes the average measured responsivity when no modulation signal is present at the device under test. This represents the noise floor of the measurement system.
