Brief Introduction

The QSFP-4SFP25G-AOCxxM-VC is QSFP28 4-channel active optical cables (AOC) for 100G Ethernet (100GbE) applications. This full-duplex optical assembly offers 4 independent transmit and receive channels, each capable of up to 25Gbps for an aggregate bandwidth of 100Gbps. The 100G QSFP28 AOC cables can be used as a direct replacement for traditional QSFP28 DAC (direct attach copper cables) and QSFP28 transceivers of short reach while providing lighter weight, improved signal integrity, lower cost, and performance value. The optical end is never exposed to a data center environment and therefore does not require cleaning or special handling. They are designed expressed for high speed, high density and low power consumption for today’s data center networking applications..

Optical transceivers port(LC)

For LC port, there are two types of single-fiber bidirectional optical transceivers (one LC connector) and dual-fiber unidirectional optical transceiver (two LC connectors).
Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals.

Optical transceivers series

Vchung offer comprehensive optical modules, data rate from 155M to 100G,form factor including SFP,SFP+,XFP,SFP28,QSFP+,CFP,CFP2 and QSFP28,support MMF and SMF interface.
Vchung closely follow optical communication market trend, offers comprehensive transceivers solution, including:
