Installation Guide for 100VG Recessed Transceivers 1995-11

HP J3027A Recessed Fiber-Optic Multimode ST Transceiver
The HP J3027A Recessed Fiber-Optic Multimode ST Transceiver connects
an HP networking device to a fiber-optic network. This transceiver is
compatible with the IEEE 802.12 and its wavelength is 1300nm. Optical
fibers conforming to the ISO/IEC DIS 11801 standard will work with this
transceiver.
Connecting the Fiber-Optic Cable
Important: Fiber-optic cables have two separate fibers for delivery of data
to and from the transceiver. The two fibers are identical, but there are several
different conventions to enable you to tell the fibers apart. For example, on
some fiber-optic cables, only one of the fibers has lettering imprinted on its
insulating sheath. Make sure that the fiber that is connected to the
transceiver’s transmit (Tx) port is connected to the receive (Rx) port on the
device at the other end of the cable, and vice versa.
To connect a fiber-optic cable to a transceiver:
1. Remove the plastic dust covers
from the cable connectors and the
transceiver jacks.
2. Match the “key” on the connector
of one of the fibers to the slot in
the transceiver’s jack. See the
illustration.
3. Press and twist the connector
onto the jack so that the pins on
the jack slide into the diagonal
slots on the connector and the
connector snaps securely into
place.
4. Repeat steps 1 and 2 for the other
fiber, connecting it to the other
jack on the transceiver.
5. When power is applied to this
transceiver in its module, the Link
or port LED should be ON. If the
LED is off, see Troubleshooting
on page 6.
