TFOCA-II® EX
Fiber Optic Connectors

Fiber Systems
InternationalThe TFOCA-II ® EX was specifically designed
for fiber optics using field-proven TFOCA-II ®
technology. The standard TFOCA-II ® EX supports
up to four single mode or multi-mode fiber opticcontacts. Using precision ceramics, the TFOCA-II ®
EX provides excellent optical performance withinsertion losses of 0.3 dB typical and 0.75 dBmaximum. The connector is also easy to terminate
with standard fiber optic tools and training.

About the TFOCA-II ®
EX Connector
Amphenol Fiber Systems International (AFSI) offers
the TFOCA-II ® EX connector to provide fiber
optic connectivity in Zone 1 and Zone 21 hazardous
environments. AFSI was awarded an ATEX
certification number (09ATEX1033X) from Sira for
its fiber optic 4-channel TFOCA-II ® hermaphroditic
plug and receptacle connectors. This certification
allows TFOCA-II ® EX connectors to mountdirectly to flameproof enclosures in hazardous
environments, providing a safe, robust and userfriendly fiber optic interface.
The TFOCA-II ® EX

is ideal for instrumentation and control systems located in petrochemical production,exploration andprocess facilities. TheTFOCA-II ® EX
eliminates the needfor hard-wired fiber
optic cable glands,
reducing deployment,
maintenance and teardown time. Also, when compared to hard-wired
cable glands, the equipment can be connected anddisconnected by minimally-trained personnel.
