Oclaro, a developer of optical communications solutions, today announced the successful qualification of its non-hermetic 25Gbit/s 1.3 μm distributed feedback (DFB) laser diodes for 100Gbit/s transceivers. Featuring leading optical performance with low operating current at high temperatures, the Oclaro 25Gbit/s DFB is a key component for enabling data centre operators to transition faster to highly meshed 100Gbit/s connections over single-mode fibre.
“The 25Gbit/s DFB laser diode is a critical component at the core of a new generation of 100Gbit/s transceivers optimized for data centre switching applications such as QSFP28 CWDM4/CLR4,” said Yves LeMaitre, President, Optical Connectivity Business at Oclaro. “By making our lasers suitable for use in non-hermetic packages, we are enabling a faster adoption of proven telecom-grade laser technologies into data centre environments. Oclaro is strongly focused on the market transition to distributed cloud networking and will continue to leverage its optical expertise to deliver cost-optimized, reliable and high-performance 100Gbit/s solutions.”
The Oclaro 25Gbit/s DFB laser diode is designed for 100Gbit/s and 25Gbit/s optical transceivers used in transmission client interface, high-end spine switch/core router interfaces and large-scale data centre meshed networks. Leveraging our experience in high-speed laser design, the 25Gbit/s DFB laser diode features higher bandwidth and lower power consumption, allowing transceiver module designers to migrate to non-hermetic designs to further reduce costs and footprint.
Additional benefits of the 25Gbit/s laser diode include the following:
- Delivers excellent eye mask performance with more than 5dB extinction ratio at 60 mA driving current at 70 degree C of transceiver module level;
- Leverages Oclaro’s cutting-edge design and mass production technology of InAlGaAs-MQW and Ridge waveguide structure to deliver optimum optical performance; and
- Completed the non-hermetic test compliant with the Telcordia GR-468-CORE issue 2 including non-hermetic damp heat/damp heat for powered non-hermetic devices.
The 25Gbit/s DFB laser diode is now fully qualified and available for production.
