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