| Product CN-8380 / 8382 - 10Base-FP Transceiver, integrated cable AUI, connector with ST/SMA Connectors |
Overview
The CodeNet 8380/8382 is a fiber optic media access unit
(FOMAU) which complies with IEEE 802.3 standard at the AUI
connection. All 838X units are equipped with an integral cable
which terminates in a male 15 pin AUI connection. The cable
provides power and electrical connections to the transceiver
and enables connection to Ethernet controllers. Since the
8380/8382 is mechanically and electrically identical to coaxial
cable transceivers at the interface cable, CodeNet fiber optic
Ethernet networks can be added to, and combined with existing coaxial cable based networks, thus allowing Ethernet
networks to be expanded and converted to fiber optics at
any time.
The 8380/8382 contains several on-board switches which
make the unit extremely versatile, allowing it to be used in a
variety of configurations. These switches include:
SQE ("Heartbeat") Test Switch: Enables the user to defeat
the SQE or "Heartbeat" test, allowing the unit to be used
with IEEE 802.3 electronic repeaters.
Mode Switch: determines whether the unit will work in passive star (standard) or point-to-point mode. The point-to-point mode enables the 8380/8382 to be used in "remote
repeater" and active star applications.
Test Switch: Allows the unit's LED transmitter to be used
as a light source for testing of a network's fiber optic cable
plant, greatly simplifying network installation.
Jabber Switch: In IEEE 802.3 mode, once the unit's
"Jabber" circuitry is tripped (indicative of a controller
malfunction), a power-up reset is required before the unit
will function again. The Jabber switch is factory set to automatic reset mode, in which the unit will automatically
reset itself once the controller clears, eliminating unnecessary down time.
Break Detection Switch: This switch can defeat the unit's
fiber break detection in passive star mode (in point to-point
mode, it is automatically defeated).
The unit also has several indicator LEDs which facilitate
troubleshooting of network problems. |
Features
Signals comply with IEEE 802.3 standard at AUI (Attachment Unit Interface) via 15-pin AUI connector.
Fiber optic network operation completely transparent to
user's hardware and software.
Supports distances up to 800 meters to the passive fiber
optic Ethernet star.
Switch selectable operating mode enables unit to function either point-to-point, or with passive star.
Fiber break detection when used with CodeStar passive
stars.
Switch selectable "Jabber" function protects system
against unnecessary downtime.
Can be used as light source for network testing of fiber
optic cable plant.
SQE "Heartbeat" test may be defeated via switch selection, allowing unit to be used with IEEE-802.3 electronic
repeaters. |
