The ST2400A meets the needs of development, manufacturing, and service engineers by providing the capabilities for:
- System Interrogation and Conformance Testing
- Manufacturing Production Testing
- Network Integrity Testing
- Network Performance Monitoring
- Network Troubleshooting
The ST2400A is the first STM-16/OC-48 test product optimized for testing 2.488-Gbps Dense Wavelength Division Multiplexed (DWDM) client systems. Its compact size, flexibility of configuration, choice of operating modes, unique I/O features, extensive software driver support, and range of error- and defect-inject capabilities make it particularly effective for DWDM system test during production and installation. It can also be used in non-DWDM SDH and SONET test applications.
The ST2400A is payload independent; external SDH/SONET 155-Mbps optical and electrical and 622-Mbps optical signals are supported in add/drop mode. The ST2400A can be ordered as an ST2400A Transceiver, as an ST2400R Receiver, or as an ST2400T Transmitter to meet a wide range of application needs economically.
The ST2400A Transceiver version can transmit and receive STM-16/OC-48 signals. The ST2400A has the ability to receive, generate, and modify an STM-16c/OC-48c signal. The transmitter section can internally generate a 2.4-Gbps signal or multiplex the higher-rate signal from STM-1 or STM-4 (OC-3 or OC-12) signal inputs. The ST2400A can also accept an STM-16/OC-48 signal in Through Mode and regenerate it. The receiver section receives an STM-16/OC-48 signal, demultiplexes it, and can drop out either the STM-1 or STM-4 (OC-3 or OC-12) signal as required.
The Transmitter version can generate and transmit the STM-16/OC-48 signal from an internal source or multiplex the higher-rate signal from either STM-1 or STM-4 (OC-3 or OC-12) signal inputs. In the case of STM-4c and STM-16c (OC-12c or OC-48c), the ST2400A can either generate four STM-4c (OC-12c) tributary signals with PRBS payloads inside an STM-16/OC-48 envelope or generate three tributary payloads of PRBS STM-4c (OC-12c) and insert a fourth from outside the tributary interface (which could contain IP traffic). In the case of STM-16c/OC-48c, the entire (single) payload is PRBS. All applicable SDH/SONET Path Pointer Bytes (H1/H2/H3) are set correctly to indicate the type of payload being carried (STM-4c/STM-16c, OC-12c/OC-48c, etc.).
The Receiver version can receive and demultiplex the STM-16/OC-48 signal and drop either the STM-1 or STM-4 (OC-3 or OC-12) signal to an auxiliary test set, as required.
ST2400A can accept zero, one, or two factory-installed 2.488-Gbps laser transmitter modules and/or zero or one APD receiver module (also referred to as I/O modules). One type of laser transmitter - direct modulated (DM) - is available.
The ST2400A provides electrical input and output clock and data interfaces operating at 2.488 Gbps. Base Transceiver configuration provides 2.488-Gbps electrical interfaces and 155/622-Mbps optical and electrical add/drop tributary interfaces. Transmitter configurations do not include 155/622 optical and electrical drop interface. Receiver configurations do not include 155/622 optical and electrical add interface.
The user can individually enable/disable laser #1 (if installed), laser #2 (if installed) and electrical outputs. Multiple outputs can be simultaneously active.
NOTE: RX will not measure correctly if both TX lasers are enabled and looped back to RX (since RX contains a broadband optical detector which is not wavelength selective).
Three Operating Modes
The ST2400A Transceiver features three operating modes to provide the flexibility you need to test today's advanced STM-16, OC-48, STM-64, OC-192, and DWDM systems. Analysis is done at the SDH/SONET Regenerator Section (Section), Multiplexer Section (Line), and Path levels independent of the payload.
Stand-Alone (Internal) Mode
Where payload testing is not required, or an external 155- or 622-Mbps tributary signal is not available, the ST2400A can operate independently. An internally-generated 2.488-Gbps test signal provides full error performance analysis and reporting of the 2.488-Gbps signal. 1.5-Mbps, 2-Mbps, and 2-MHz external-reference clock signals or an internal clock signal can be used to time the transmitted signal in internal mode. Internal mode is ideal for DWDM SDH/SONET client system testing, where transmission quality test time and cost can be lowered through the use of a high-speed signal.
Active Through Mode
Through Mode allows overhead bytes to be passed or edited while regenerating the received 2.488-Gbps signal. Alarms and errors can also be added to the received signal prior to retransmission. This mode is especially valuable for testing framing synchronization and protection switching and for diagnosing system interoperability problems. 155- or 622-Mbps signals can be dropped from the receiver for path-level analysis on another tester.
Add/Drop (External) Mode
In this mode, the ST2400A transmitter creates the 2.488-Gbps signal from an externally added 155- or 622-Mbps SDH or SONET signal. The external signal can be copied into one or all available payload envelopes in the 2.488-Gbps signal. The ST2400A receiver performs 2.488-Gbps level testing and, as required, drops a tributary signal for path-level analysis by a Tektronix CTS850, CTS710, ST112, or any other 155- or 622-Mbps SDH or SONET test set. Previous investment in lower-speed test equipment is preserved.
Emulation of Real SDH/SONET Systems
The ST2400A provides two features that let the tester emulate real network conditions. First, a 223-1 or 231-1 PRBS pattern can be generated to produce a synchronous signal that behaves like live traffic. Second, the optical receiver's decision threshold can be offset to emulate older SDH/SONET network elements that are deployed in the field and which can create interoperability issues when connected to optically amplified systems such as DWDM. By controlling what the ST2400A considers a "one" or a "zero," true system transmission quality can be determined, installed behavior predicted, and optimized in the factory.
DWDM Parallel Channel Test
Because DWDM systems carrying SDH/SONET clients are expected to operate at a transmission quality level of 10-12 BER or better per ITU-T G.692 and Bellcore GR-2918, per-channel transmission quality test cycles can easily exceed twelve hours. By testing all channels in parallel, system test time can remain constant as channel counts increase from eight to sixteen to thirty-two and beyond. The ST2400R Receiver provides the means for highly cost-effective simultaneous multichannel analysis. A Receiver can measure the transmission performance of each channel of the multiwavelength system, while a ST2400T Transmitter is used to generate the 2.488-Gbps signal, which can be split to multiple inputs of the DWDM system. The Parallel Channel Test is illustrated in the figure below.
DWDM Parallel Channel Test
Help in Lowering Per-Channel Test Time
In addition to using the ST2400A for effective parallel channel testing, the product can also help lower per-channel test time.
Accelerating Low BER Measurement Through Extrapolation
Measuring the low error rates that DWDM systems promise can take a minimum of 11 hours at 2.488 Gbps. The ST2400A provides a way in some applications to save test time by extrapolating to low BERs through offset of the optical receiver's decision threshold.
Improved Test Convenience
If the system has been characterized in design, then many of these tests need not be repeated further down the value chain. The power of the ST2400A is focused on system transmission quality verification during production and installation. For production test, a full remote command set plus LabView and LabWindows CVI, HP-VEE drivers help manufacturing engineers create automated test suites quickly and efficiently. A "pause" feature enables tests to be suspended while rearrangements are made, which allow long-term testing to proceed. Tests can also be automatically resumed after lost power is restored, again saving retest time. Finally, by using the ST2400A in constant wavelength (unmodulated) mode, optical tests such as OSNR and spectral width can be done without the need for an additional laser source.
2.488-Gbps Interface Choices
For manufacturers and installers of DWDM equipment, the ST2400A offers a low-dispersion, long reach 1550-nm laser option that provides enhanced performance. In addition, the low-dispersion optics can be ordered at specific ITU-T G.692 grid frequencies to meet precise requirements. If low-dispersion optics are not required, the ST2400A long-reach 1310-nm optics can be ordered. A dual 1310/1550-nm wavelength option is provided for customers who need flexibility. Finally, a customer can choose to configure units with only 2.488-Gbps electrical I/O. This feature is provided for applications such as laser-driver module tests where optics are not required.
±1-nm Wavelength Tuning
The ST2400A provides the capability to "tune" the wavelength of its 1550-nm laser from its nominal value up or down by one nanometer. This feature allows the user to check adjacent channels on the G.692 frequency grid without purchasing additional specific wavelength lasers. This feature would typically be useful in testing DWDM systems without transponders or in testing transponder-based systems when the transponder is not part of the test setup.
STM-64/OC-192 Tributary Testing
Testing 10-Gbps systems at the line rate requires very expensive test equipment. These systems can be tested more economically at the 2.488-Gbps tributary rate using the ST2400A.

Output Signal Structure
1. Active THRU (Through) Mode
Regenerated with recomputed B1, B2 but otherwise unaltered or with user-modified overhead, added defects or added errors from the received 2.488-Gbps input signal using the recovered clock. Jitter transfer from 2.488-Gbps input to output is filtered by a 1-MHz (nominal) bandwidth PLL (typical 0.3-dB jitter transfer).
2. EXT (Terminal) Mode
155- or 622-Mbps tributary signals are added from an external SDH or SONET test set. 2.488-Gbps signal is generated using clock recovered from the add input. Tributary signals added into any 1 of 16 (155 Mbps) or any 1 of 4 (622 Mbps) payload locations or duplicated to fill all payload locations. Unused payload locations are VC-4 structured STM-1 (SDH mode) STS-3C structured STS-3, or 3 x STS-1 (SONET mode) structured with unequipped path overhead (J1=0, C2=0, correct B3, remainder of path overhead = 0). The remainder of the channel payload is bulk-filled with user-selected test pattern (all Zeros, ITU-T 0.181 223-1 PRBS, or 223-1 PRBS). In "all" mode, the tributary overhead is copied to fill all the 2.488-Gbps overhead; in "single" mode, one copy is made for the selected location and all other locations are filled with "unequipped" channel overhead and user-selected test patterns (all Zeros, ITU-T 0.181 223 -1 PRBS or 223-1 PRBS).
3. INT (Stand-Alone) Mode
2.488-Gbps signal is VC-4 structured STM-1 (SDH), STS-3C structured STS-3, or 3 x STS-1 (SONET) structured and filled with test patterns as in External Mode.
