Breaking the Speed Barrier with QSFP28 100G PSM4 Transceivers 

In today’s fast-paced digital world, high-speed data transmission is a must. Whether you’re running a data centre, managing a network infrastructure, or looking to upgrade your internet connectivity, speed matters. This is where QSFP28 100G PSM4 transceivers come into play. These advanced optical transceivers are changing the game when it comes to
high-speed data transmission. In this article, we will dive deep into QSFP28 100G PSM4 transceivers, their features, benefits, and applications. 

Understanding QSFP28 100G PSM4 Transceivers 

What is QSFP28 100G PSM4? 

QSFP28 stands for Quad Small Form-Factor Pluggable 28. It’s a compact, high-speed transceiver module designed for various applications, including data centres and telecommunications. The “100G” indicates that it’s capable of transmitting data at a rate of 100 gigabits per second (Gbps), making it perfect for high-bandwidth requirements. 

PSM4 stands for Parallel Single-Mode 4. It’s a specific optical technology that allows QSFP28 transceivers to transmit data using four parallel single-mode fibre connections. This technology enhances data transmission efficiency and reliability, especially over longer distances. 

Features & Applications –  

  • Hot-pluggable QSFP28 form factor 
  • Compliant with QSFP MSA standard; Compliant with 100G PSM4 MSA standard 
  • 4 channels full-duplex transceiver module; Supports 100Gb/s aggregate bit rate 
  • 4 channels 1310nm DFB lasers; 4 channels PIN photo detector array 
  • Maximum link length of 2km on SMF 
  • Single MTP/MPO receptacle; Built-in digital diagnostic functions 
  • 3.5W maximum power dissipation; Single 3.3V power supply 
  • Operating case temperature range: 0 to 70°C 
  • RoHS-6 compliant (lead free) 
  • 100GE direct interconnection 
  • 100GE to 4x 25GE breakout interconnection 

How Does QSFP 100G PSM4 Work? 

The QSFP 100G PSM4 converts parallel electrical input signals into parallel optical signals by the Layser Array and then transmits them in parallel on the MTP/MPO single-mode ribbon fibre. Upon reaching the receiving termination, the PIN array converts the parallel optical signals into parallel electrical signals. The QSFP28 PSM4 module works in much the same way as the QSFP28 SR4 optical transceiver. The difference is that the former operates on single-mode fibre while the latter operates on OM3/OM4 multimode fibre.
