100G, 1310nm, 40KM, QSFP28, ER4

This product is a 100Gb/s transceiver module designed for optical communication applications compliant to Ethernet 100GBASE-ER4 standard. The module converts 4 input channels of 25Gb/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of LAN WDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309.14 nm as members of the LAN WDM wavelength grid defined in IEEE 802.3ba.

Overview

This product is a 100Gb/s transceiver moduledesigned for optical communication applications compliant to Ethernet100GBASE-ER4 standard. The module converts 4 input channels of 25Gb/selectrical data to 4 channels of LAN WDM optical signals and then multiplexesthem into a single channel for 100Gb/s optical transmission. Reversely on thereceiver side, the module de-multiplexes a 100Gb/s optical input into 4channels of LAN WDM optical signals and then converts them to 4 output channelsof electrical data.

The central wavelengths of the 4 LAN WDMchannels are 1295.56, 1300.05, 1304.58 and 1309.14 nm as members of the LAN WDMwavelength grid defined in IEEE 802.3ba. The high-performance cooled LAN WDMDFB transmitters and high sensitivity APD receivers provide superiorperformance for 100Gigabit Ethernet applications up to 40km links.

The product is designed with form factor,optical/electrical connection and digital diagnostic interface according to theQSFP+ Multi-Source Agreement (MSA). It has been designed to meet the harshestexternal operating conditions including temperature, humidity and EMIinterference.

Notes:

1. The minimum average launch power spec is based on ER not exceeding 9.5dB andtransmitter OMA higher than 0.1dBm.

2. Even if the TDP < 0.75 dB, the OMA min must exceed the minimum value specified here.

3. 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.

4. Vertical eye closure penalty, stressed eye J2 jitter, and stressed eye J9 jitter are test conditions for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
