81490A Reference transmitter for optical receiver limit testing

Overview and Features • 33 GHz typical optoelectronic bandwidth • Optical wavelengths: 1310 nm and 1550 nm single-mode fiber, 850 nm multi-mode fiber • Rise time and fall time: < 25 ps, < 15 ps (typical) • Jitter: < 0.2 UI, < 0.15 UI (typical) The Keysight 81490A reference transmitter is optimized to provide excellent eye diagram quality. As a reference configuration, it can perform 10 GbE-LR, -ER, -SR tests according to IEEE 802.3ae, and 100GBASE-LR4, -ER4, -SR4 tests according to IEEE 802.3bs and 10/16 G FC Fibre Channel specifications. By integrating into the Keysight LMS platform, it can perfectly cooperate with the N4917A/B optical receiver limit test solution to perform tests. The wide modulation bandwidth of up to 35 GHz enables it to form an excellent test setup with an electrical waveform generator to provide arbitrary optical modulation signals. Advantages • By using the N4917A/B optical receiver limit test solution in combination, it fully complies with IEEE 802.3ae –LR, -ER, -SR and IEEE 802bs -LR4, -ER4, -SR4 specifications. • The 1310 nm and 1550 nm single-mode fiber transmitters are included in one module, thus saving test time and cost. • The module with an external laser source input can support the 1300nm WDM band. • 850nm multi-mode fiber transmitter. • It has excellent scalability and can be integrated into the industry-standard Keysight LMS platform to increase the test capabilities of the optical test platform. • It has a 35 GHz analog modulation bandwidth and can be used in combination with an electrical arbitrary waveform generator to expand the application scope to generate arbitrary optical waveforms.
