The engineer solved our problem very quick, and the service is very good. Very professional factory.

—— Robert Lichtenstein-Canada

I had no concern, was buying and testing, so equipment is ok. So equipment and logistic is ok, we keep ordering and making business.

—— Anek – Thailand

I'm very satisfied with the media converter received, the OEM order quality is good.

—— Faize Akçaba-Turkey

E-link Sales are very professional, they give me not only product, but also solution. All E-link Fiber Media Converters and PoE Switches works well.

10kmSingle Mode Fiber SFP Optical Transceiver Module Support 40Gb / S QSFP+ PSM LR4




The E-link LNK-QSFP-LR4-10KM is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP+ Transceiver for InfiniBand QDR/DDR/SDR,10G/8G/4G/2G fiber channel , PCIe and SAS Applications.


The QSFP full-duplex optical module offers 4 independent transmit and receive channels, each capable of 10.3Gbps operation for an aggregate data rate of 40Gbps 10km using single mode fiber.


These modules are designed to operate over single mode fiber systems using 1310nm DFB laser array.


An optical fiber ribbon cable with an MPO/MTPTM connector can be plugged into the QSFP module receptacle.


QSFP+ PSM LR4 is one kind of parallel transceiver which provides increased port density and total system cost savings.




● Four-channel full-duplex transceiver modules

●Transmission data rate up to 11.2Gbit/s per channel

●Up to 10km transmission of single mode fiber

●Low power consumption <2.5W,meet class 3

●Operating case temperature 0°C to +70°C

●3.3V power supply voltage

●RoHS 6 compliant

●Hot Pluggable QSFP form factor

●Single MPO connector receptacle

●Built-in digital diagnostic function





● InfiniBand QDR, DDR and SDR

● 40G Ethernet

● Proprietary High Speed Interconnections

● Data center


The operation in excess of any absolute maximum ratings might cause permanent damage to this module.
