Instruction Manual – DXLink Fiber™ Transmitters and Receivers, Duplex
Fiber Optic Cable Requirements
Fiber Optic Cable Requirements
Fiber optic cable with LC termination for snap coupling with SFP+ transceivers
LC Duplex conforming to ANSI TIA-EIA 604-10 (FOCIS 10A)
MM duplex units require OM3 50/125
μ
m multimode fiber optic cable; maximum length 984 feet (300 m)
SM duplex units require 9/125
μ
m single mode fiber optic cable; maximum length is 6.21 miles (10 km)
Important:
Be sure to follow the fiber optic cable manufacturer’s recommendations.
Tip:
Multimode transceivers only – If you are unsure that a multimode transceiver is passing a signal, hold the
unattached end of the fiber optic cable
away from you
and take a picture of it with a digital camera (or cell
phone camera). The image will show a bright light if signal is being passed (works on some digital cameras).
Fiber Optic Cable Wiring for Bidirectional Full System Capabilities
When wiring fiber optic cable for bidirectional full system capabilities, a dual set of fiber optic cables is used to wire
from a DXLink Fiber Transmitter to a DXLink Fiber Input Board and another dual set of fiber optic cables from a
DXLink Fiber Output Board to a DXLink Fiber Receiver. This wiring provides not only video and audio but Ethernet,
IR, serial, and USB functionality as well.
Fiber Optic Transceiver LEDs
The following information applies to the LEDs above the fiber optic transceiver on the units.
Twisted Pair Cable for ICS LAN 10/100 Connection
Cable Pinout
Either T568A or T568B pinout specification for termination of twisted pair cable can be used for ICS LAN 10/100.
Warning:
DXLink Fiber units use laser transceivers, which are Class 1 Eye Safe per IEC 60825-1/CDRH
requirements. While the Class 1 category indicates that the invisible laser used is safe, we recommend
avoiding direct eye exposure when using any optical fiber products (see the OSHA directive on page 13).
Caution:
Do not severely bend or kink the fiber optic cable. Irreversible damage can occur. Refer to the
physical limitations (bend radius) specified by the cable manufacturer.
