Description
The ABPTEL 400G-QDD-LR4 is a high-performance, long-reach optical transceiver designed for 400 Gigabit Ethernet applications. Operating in the QSFP-DD form factor, it supports data rates up to 425Gbps and provides reliable transmission over 10km single-mode fiber (SMF).
This module leverages four CWDM wavelengths (1271nm, 1291nm, 1311nm, 1331nm) multiplexed into a duplex LC optical interface, ensuring seamless high-speed connectivity. With a PIN receiver, CWDM EML transmitter, and ≤9W low power consumption, the ABPTEL 400G LR4 transceiver offers superior performance for data center interconnects, enterprise backbone networks, and telecom infrastructures.
Fully compliant with QSFP-DD MSA, IEEE 802.3bs, and 400GAUI-8 standards, the ABPTEL 400G-QDD-LR4 guarantees interoperability and future-ready scalability for next-generation networks.
