400G QSFP-DD LR4/ER4-30
400G QSFP-DD LR4/ER4-30
The NEC's 400G QSFP-DD optical transceiver is a cost-effective optical transceiver that achieves 400G transmission by applying the technology of 100G Single λ products.
Without using coherent technology, it is an extension of the existing 100G Single λ technology and does not require complex processing. As a result, it can use low-power DSP, enabling low power consumption for 400G transmission.
In addition, it can be connected to the 100G QSFP28 8λ product for breakout connections, providing a flexible network configuration according to customer requirements.
NEC offers products with transmission distances of 10km and 30km, supporting the transition of customers' networks to 400G.
Features
- Achieves 400G in a QSFP-DD size configuration of 4λ x 100G.
- Capable of 10km and 30km transmissions.
- Can be connected to 100G QSFP28 Singleλ 8λ products for breakout connections.
- Supports O-band WDM filters in breakout configurations.
