Frequently Asked Questions
What is the maximum reach of the EQD400-LR8 transceiver?
The EQD400-LR8 QSFP-DD transceiver supports a maximum transmission distance of up to 10KM over single-mode fiber (SMF) using LC connectors.
Which 400G QSFP-DD models utilize MPO connectors?
Both the EQD400-SR8 (850nm, 100M) and EQD400-DR4 (1310nm, 500M) optical transceivers are designed to operate with MPO interface connectors.
What is the operating temperature range for these QSFP-DD modules?
All listed 400G QSFP-DD transceivers, including SR8, DR4, FR4, LR4, and LR8 models, support a standard commercial operating temperature range of 0 to 70℃.
What is the difference between EQD400-FR4 and EQD400-LR4?
While both modules feature a 1310nm wavelength and LC connectors, the EQD400-FR4 is designed for shorter reaches up to 2KM, whereas the EQD400-LR4 supports long-distance transmissions up to 10KM.
What laser types are used in these 400G transceivers?
The transceivers use various advanced laser designs: VCSEL+PIN for short-range (SR8), EML+PIN for DR4 and LR8, and ENL CWDM+PIN for medium to long-range (FR4 and LR4) options.
