40G BASE QSFP+ Transceiver Module


        X-Krama's 40G optical module refers to an optical module with a transmission rate of 40Gbps, and its
commonly used packaging form is QSFP+. It is a product derived from the demand for higher-density high-speed
pluggable solutions. There are 4 independent transmit and receive optical signal channels, each with a transmission rate of 10G, which can provide high-density and low-power 40G Ethernet high-speed interconnection for data centers, high-performance computing networks, and telecom operators. But the 40G product layout is also a transitional product, completing the transition from 10G to 100G speed.



  Features :


  • Supports up to 11.2Gbps data rate per channel

  • Transmission up to 10 km on 9/125μm SMF

  • 4 channels full-duplex transceiver modules

  • 4 CWDM un-cooled DFB lasers, 4 PIN receivers with optical DEMUX

  • Using ITU G.694.2 wavelength grid at 1271nm, 1291nm, 1311nm, and 1331 nm

  • LC Duplex connector

  • Compliant with QDR/DDR InfiniBand data rates

  • Compliant to IEEE 802.3ba specification for 40GBASE-IR4 links

  • QSFP+ MSA compliant

  • Built-in digital diagnostic functions

  • Hot pluggable QSFP  form factor

  • Low power dissipation

  • Metal enclosure, for lower EMI

  • RoHS compliant and lead-free

  • Single +3.3V power supply

  • Operating case temperature: Standard :  0 to +70°C



 Applications :


  • 40G Ethernet and OTU3

  • Fiber Channel

  • Datacom/Telecom switch & router connections

  • Infiniband transmission at 4ch SDR, DDR and QDR

  • Data Aggregation and Backplane Applications

  • Proprietary Protocol and Density Applications
