100G QSFP28-4WDM-10 QSFP28 optical module

Product Overview:
This product is a 100Gb/s transceiver module designed for optical communication applications, conforming to the 100GBASE-4WDM-10 standard in the IEEE P802.3ba standard. The module converts 25Gb/s electrical data from four input channels into four CWDM optical signal channels, then multiplexes them into a single channel to achieve 100Gb/s optical transmission. Conversely, the receiving end demultiplexes the 100Gb/s optical input into four CWDM optical signal channels, then converts them into electrical data for four output channels.
The center wavelengths of the four CWDM channels are 1271, 1291, 1311, and 1331 nanometers, all members of the CWDM wavelength grid defined by IEEE 802.3ba. A high-performance cooled CWDM DFB transmitter and a high-sensitivity PIN receiver provide superior performance for 100Gb Ethernet applications (up to 10km links).
The product design incorporates a QSFP+ Multi-Source Protocol (MSA) compliant form factor, optoelectronic connections, and digital diagnostic interfaces. It is designed to withstand the most demanding external operating conditions, including temperature, humidity and electromagnetic interference.

Optical Characteristics 
Table 3 – Optical Characteristics

 Note：

• Even if the TDP < 1 dB, the OMA min must exceed theminimum valuespecified here.
• See Figure 4 below.
• 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.
• Measured with conformance test signal at receiver inputfor BER = 5E-5
• Vertical eye closure penalty and stressed eye jitter are test conditions for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
