HFE7192-XXX

DATA 

SHEET

The HFE7192-xxx uses a high-performance Vertical Cavity Surface Emitting

Laser (VCSEL) designed to meet performance requirements for 1/2/4/8 Gbps

data communication over multimode optical fiber for the ANSI X2.T11 Fibre

Channel protocols. The optical assembly is designed to interface either 50

µm 

or 62.5

µm multimode fiber and ensure launch conditioning requirements

compatibility with enhanced bandwidth fiber as specified by TIA 455-203.

The HFE7192-xxx incorporates a power monitoring photodiode that can 

be used for temperature compensation, average power control, and for

compliance with Class 1 eye safety limits.
