≥ 5d.
Fiber Single-mode G.657A2 optical ber: R ≥
10 mm (0.39 in.), bending angle > 90°
Multi-mode A1b optical ber: 30 mm
(1.18 in.) ≤ R ≤ 40 mm (1.57 in.),
bending angle > 90°

Precautions for Installation
● Hold terminals of cables instead of pulling the cables themselves when
installing or removing cable components.
● Do not insert a connector forcibly when the connector is blocked. Use a

check that the pins are inserted properly.
● Before tightening screws on cable connectors, ensure that the connectors are
properly connected to their adapters. Tighten the screw with appropriate force
using a
at-head or Phillips screwdriver instead of bare hands or an electric
