Short Description

QSFP28 100Gb/s ER4  QSFP28 100G, 1340nm, 40km, ER4 Single Mode

Applications:

  • 100GBASE-ER4 Ethernet Links
  • Infiniband QDR and DDR interconnects

This NETRO NN-QSFP28-100G-ER4 This product is a 100Gb/s transceiver module designed for optical communication applications compliant to Ethernet IEEE 802.3ba 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 standard. The high performance cooled LAN WDM DFB transmitters and high sensitivity APD receivers provide superior performance for 100Gigabit applications up to 30km links and compliant to optical interface with 100GBASE-ER4 lite requirements.

The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the NETRO NN-QSFP28-100G-ER4 Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.

Notes:

  1. Even if the TDP < 1 dB, the OMA min must exceed the minimum value specified here.
  2. See Figure 1 below.
  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.

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