商品描述
The WST-QD4-LR4-C is a hot-pluggable 400G QSFP-DD LR4 optical transceiver designed for 400 Gigabit
Ethernet applications over single-mode fiber.
The module supports an eight-lane 53.125 Gb/s PAM4 electrical host interface and four optical lanes
operating at 106.25 Gb/s PAM4. A DSP-based signal processing architecture is used to enable signal
conversion between the electrical and optical interfaces.
On the transmit side, electrical signals drive four CWDM EML transmitters operating at nominal
wavelengths of 1271 nm, 1291 nm, 1311 nm, and 1331 nm. On the receive side, the optical signals are
detected by a PIN photodiode array. The optical interface uses a duplex LC connector.
The module supports transmission distances up to 10 km over G.652 single-modefiber and is intended for
operation in systems with host-side forward error correction (FEC). It operates from a single 3.3 V power
supply and complies with IEEE 802.3cu, IEEE 802.3bs, and QSFP-DD MSA requirements.
