N-Type

The N-Type connector is used for intrusive taps in thick coaxial cabling. The
instructions which follow detail the process used to connect a male N-Type
connector to a female N-Type barrel connector.
Before attaching a male N-Type connector to a female N-Type barrel connector or
terminator, look into the end of the male connector to verify that the gold contact
pins are present and centered. Any bent or broken pins may not connect properly
and should be replaced.
1. Slide the threaded metal housing of the male connector straight over the
2. Once the housing stops moving in, turn the metal housing clockwise while

ST Connector

Each fiber optic link consists of two strands of fiber optic cabling: the transmit
(TX) and the receive (RX). The transmit strand from a module port connects to the
receive port of a fiber optic Ethernet device at the other end of the segment. The
receive strand of the applicable port on the module connects to the transmit port
of the fiber optic Ethernet device.
Cabletron Systems recommends labeling fiber optic cables to indicate receive and
transmit ends. Many cables are prelabeled, providing matching labels or tapes at
both ends of each strand of cable.
The instructions which follow detail the process used to connect an ST connector
to a station port.
