Brief Introduction

The Vchung QSFP28 Optical Transceiver Module is designed for use in 100GBASE Ethernet throughput up to 200m over OM3 MMF or 300m over OM4 MMF using a wavelength of 850nm via a MTP/MPO-12 connector. This transceiver is compliant with IEEE 802.3bm 100GBASE-SR4 and CAUI-4 standard. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP28 MSA, to allow access to real-time operating parameters.
With these features, this easy-to-install, hot swappable transceiver is suitable to be used at key locations optical networks like 100GBASE Ethernet.

QSFP28-100G-eSR4 QSFP28 100GBASE-ESR4 850nm 300m OM4 DOM MPO-12/UPC MMF Optical TransceiversOptical 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.
