Mitsubishi sampling 50Gbps DFB laser diode for OFC in 5G

Mitsubishi said it has started sample shipment of its 50Gbps distributed-feedback (DFB) laser diode for optical-fiber communication in fifth-generation (5G) mobile base stations on March 4. The new diode is design to be fully compliant with all relevant optical-transceiver standards and can operate at wider temperature range of -40C to 90C for high-speed, large-capacity data transmission in 5G mobile networks.

Product Features include:

1)Supports 50Gbps high-speed, large-capacity 5G communication in PAM4 format
Mitsubishi Electric's new DFB laser diode's frequency-response characteristics are compatible with 4-level pulse-amplitude modulation (PAM4) for multilevel signal modulation, supporting transmission rates up to 50Gbps. Also, its industry-leading operating temperature range of -40C to 90C eliminates the need for any temperature-control unit, helping to reduce power consumption by mobile base stations.
2)Compliant with TO-56 CAN standard for compact optical transceiver packages

The new diode's package is compliant with the TO-56 CAN industry standard and is compatible with the SFP56 compact-transceiver standard adopted for Mitsubishi Electric's 25Gbps DFB laser diode (model ML764AA58T; production discontinued).

The laser diode model ML771AA74T emitt laser at wavelength of 1310nm with optical power of 8mW.
