Introduction

The 100G QSFP28 (Quad Small Form-factor Pluggable 28) is a high-density, high-speed optical transceiver module that utilizes four-channel parallel transmission technology, with each channel supporting data rates up to 25 Gbps, for an aggregate bandwidth of 100 Gbps. Designed for data centers, high-performance computing, and telecommunications networks, it meets the growing demand for high-bandwidth, low-power consumption connectivity.

FIBERMART’s QSFP28 Transceiver portfolio consists of transceivers which can operate over Single Mode or Multi Mode optical fiber, can be used for connections from couple of meters up to 80 kilometers and are suitable for 100G Ethernet, Optical Transport Network OTU4 and 128G Generation 6 Fiber Channel applications. Our QSFP28 transceiver portfolio is fully compliant to industry standards (QSFP28 MSA) and can work in 80% of networking equipment, where is not implemented special algorithm for protection against third party modules. However - we have accumulated deep expertise in custom-encoded firmware for our 100G QSFP28  portfolio in order to make it work in almost any brand equipment. 100g transceivers for sale.

Principle

The 100G QSFP28 transceiver module enables high-speed data transmission through electrical-to-optical and optical-to-electrical conversion. On the transmitter side, it receives four independent 25 Gbps electrical signals from the network equipment. An internal laser driver and laser array then convert each electrical signal into an optical signal at a specific wavelength. For multimode fiber (SR4), the four optical signals are transmitted in parallel through separate fibers within an MPO connector. For single-mode fiber (LR4), CWDM (Coarse Wavelength Division Multiplexing) technology is used to combine the four optical signals at different wavelengths onto a single fiber. On the receiver side, the optical signals are converted back into electrical signals by a photodetector array, then undergo clock recovery and signal reshaping before being output to the host device. The entire process is managed by an integrated controller and supports real-time digital diagnostic monitoring to ensure signal integrity and link stability.

Applications

● Data Center Interconnects: Ideal for server connects, leaf-spine architectures, and high-speed intra-data center links.

● High-Performance Computing (HPC): Enables high-speed data exchange between cluster nodes.

● Telecommunications Core Networks: Supports 100G Ethernet, OTN (Optical Transport Network).

● Enterprise Networks: Suitable for core switch uplinks or high-bandwidth aggregation layer connections.

● Cloud Services & Storage Networks: Meets the demands of large-scale storage and virtualized environments.
