Oclaro completes qualification of non-hermetic 25Gb/s DFB lasers for 100Gb/s transceivers

Oclaro Inc of San Jose, CA, USA (which provides components, modules and subsystems for optical communications) says that its new non-hermetic 25Gbit/s 1.3μm distributed feedback (DFB) laser diodes for 100Gb/s transceivers are now fully qualified and available for production, after having completed the non-hermetic test compliant with Telcordia GR-468-CORE issue 2 (including damp heat/damp heat for powered non-hermetic devices).

Leveraging Oclaro's design and mass-production technology of InAlGaAs-MQW and ridge-waveguide structure to deliver optimum optical performance while also featuring low operating current at high temperatures, the 25Gb/s DFB is a key component for enabling data-center operators to transition faster to highly meshed 100Gb/s connections over single-mode fiber, says the firm.

"The 25Gb/s DFB laser diode is a critical component at the core of a new generation of 100Gb/s transceivers optimized for data-center switching applications such as QSFP28 CWDM4/CLR4," says 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-center environments," he adds. "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 25Gb/s DFB laser diode is designed for 100Gb/s and 25Gb/s optical transceivers used in transmission client interface, high-end spine switch/core router interfaces and large-scale data-center meshed networks. The new 25Gb/s DFB laser diode features high bandwidth and low power consumption, allowing transceiver module designers to migrate to non-hermetic designs to further reduce costs and footprint, says the firm.
