Description
This product is a 40Gb/s transceiver module designed for optical communication applications compliant with the 40GBASE-ER4 of the IEEE 802.3bm standard.
The module converts 4 input channels of 10Gb/s electrical data to 4 channels of CWDM optical signals and then multiplexes them into a single channel for 40Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 40Gb/s optical input into 4 channels of CWDM optical signals and then converts them to 4 output channels of electrical data.
The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G.694.2.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
Absolute maximum ratings
These values represent the damage threshold of the module. Stress in excess of any of the individual Absolute Maximum Ratings can cause immediate catastrophic damage to the module even if all other parameters are within Recommended Operating Conditions.

Notes:
1. Even if the TDP < 0.8 dB, the OMA min must exceed the minimum value specified here.
2. The receiver shall be able to tolerate, without damage, continuous exposure to a modulated optical input signal having this power level on one lane. The receiver does not have to operate correctly at this input power.
3. Measured with conformance test signal at receiver input for BER = 1x10-12.
