3-1-3 Connecting the Optical Connector (Optical Fiber)
Insert the optical connector firmly and completely into the
connector adapter. If the connection is not sound,
measurements will be inaccurate.
■
Optical Fiber
Supports single mode: (9/125 µm) and multimode: GI (50/125
µm), GI (62.5/125 µm).
■
Ferrule
Supports PC and FLAT polish.
Performance is not guaranteed with angled PC.
* Regarding support for APC (angled PC) fiber
(1) There are many kinds of angled PC connector polishes.
Performance is not guaranteed with angled PC connectors
because the measured value depends on the shape of the tip.
However, it should be noted that with single mode fiber,
measured values using an eight-degree APC connector are
nearly identical to those when using a PC connector.
(2) When connecting an APC connector to the receptacle, defects
can, very rarely, be found in the ferrule tip. Such defects are
not representative of the overall characteristics of the
instrument. Also, APC connectors are intended to create
low-reflection J-J connections, and therefore connections with
a receptacle cannot be fully guaranteed. If a defect should be
found, the cause is most likely a splinter. Consequently, any
damage incurred by the instrument or to the customer's optical
fiber as a result of a defective APC connector ferrule tip is not
covered under warranty.
Always use an optical connector that matches the instrument.
Also, before making connections, clean the ends with a
dedicated cleaner.
Dedicated cleaners for cleaning optical connectors are
available from NTT, including the NTT-AT “OPTIPOP-R”
(NTT-AT), and the “CLETOP Real-Type” (NTT-ME).
