Description
ETSC’s OM3660DX102 is a transceiver module designed for 500 m optical communication applications, and it is compliant with QSFP-DD MSA, IEEE 802.3bs protocol and 400GAUI-8 standards. The 425 Gigabit signal is carried over four parallel lanes by one wavelength per lane. This module can convert 8-channel 53.125 Gbit/s electrical data to 4 parallel channels of optical signals, each supporting 106.25 Gbit/s data transmission. Reversely, it can convert 4-channel 106.25 Gbit/s optical signals to 8-channel electrical output data on the receiver side. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The module offers very high functionality and feature integration, accessible via a two-wire serial interface.

Notes
- Receiver sensitivity (OMA outer), each lane (max) is informative and is defined for a transmitter with SECQ of 0.9 dB.
- Measured with conformance test signal for BER = 2.4 x 10 – 4. A compliant receiver shall have stressed receiver sensitivity (OMA outer), for SECQ values between 0.9 and 3.4 dB.
