1. Product description
Typical deployment
This PTP 600 Series optical interface upgrade kit allows connection of a PTP 600 Series
ODU to a network over a 1000BaseSX or 1000BaseLX fiber interface:
Power over Ethernet
When the fiber interface is installed, the ODU is powered over a standard CAT5e
Ethernet cable connected to either the 1000BaseT port (labeled PIDU+) or, on earlier
versions, the power port (labeled PWR).
ODU units with a ‘Mod Record’ label showing ‘1’ or higher are powered via the
1000BaseT port:
Earlier versions are identified by the fact that they do not have a ‘Mod Record’ label on
the back of the ODU.

62.5/125 Multi 160 220 m (720 ft) 2.38
62.5/125 Multi 200 275 m (900 ft) 2.6
50/125 Multi 400 500 m (1640 ft) 3.37
50/125 Multi 500 550 m (1800 ft) 3.56
The 1000BaseLX (1310 nm) module specifications are:
Core/ Mode Bandwidth at Maximum Insertion
cladding 1310 nm length of fiber loss (dB)
(microns) (MHz/km) interface
62.5/125 Multi 500 550 m (1800 ft) 1.67
50/125 Multi 400 550 m (1800 ft) 0.07
50/125 Multi 500 550 m (1800 ft) 1.19

8. 1. Product description PTP 600 Series Optical Interface Upgrade Guide
Contents of the upgrade kit
The SFP optical module may be damaged by ESD. It is supplied in an ESD protective
case. Observe ESD handling procedures when unpacking and installing the module.
The performance of 1000BaseSX and 1000Base LX connections can be seriously
affected by dust build up. Keep all dust covers in place until just before the connection
is to be made.
The optical upgrade kit contains the following items:
• SFP optical module:
Either 1000BaseSX:
Or 1000BaseLX:
• Extension tube (complete with ‘O’ ring seal):
• Weatherproofing Gland:
• Instruction manual (on CD) – this document
• License key instructions and unique Access Key

9. 1. Product description PTP 600 Series Optical Interface Upgrade Guide
Fiber optic cable and connectors
The fiber optic cable and connectors are not supplied as part of the optical upgrade kit.
Order them from a specialist fiber optic cable fabricator, quoting the following
specification:
This specification is based on the following considerations:
• Individual LC connectors are specified to aid installation and removal of the fiber
optic cable assembly to and from the SFP module installed in the ODU.
• The finished diameter of the cable where the weatherproofing gland clamps the
cable should be between 6 mm and 7 mm. If the finished diameter is less than 6 mm,
the weatherproofing gland may not seal correctly. If the finished diameter is greater
than 7 mm it will be difficult to assemble the weatherproofing gland without
damaging the fiber optic cable.
• Assembly can be made easier by fitting the weatherproofing gland before fitting the
connectors to the fiber optic cable.
• LC connectors should be supplied with dust caps to prevent dust build up.

11. 2. Installing the optical interface PTP 600 Series Optical Interface Upgrade Guide
4 Remove the optical dust protection cap.
Connecting the fiber optic cable
The fiber optic cable assembly is very delicate. To avoid damage, handle it with
extreme care. Ensure that the fiber optic cable does not twist during assembly,
especially when fitting and tightening the weatherproofing gland.
To connect the fiber optic cable to the SFP module, proceed as follows:
1 Thread the gland and extension tube over the fiber optic cable as shown.
Thread the gland onto the fiber optic cable before termination. It is possible to
thread the LC connectors through the gland by separating the rubber seal into
its component parts, then stretching them open with a sleeve spreading tool.

19. 3. Configuring the optical interface PTP 600 Series Optical Interface Upgrade Guide
Configuring SFP
If the SFP optical module is not automatically sensed by the PTP 600 unit, the SFP
Configuration menu option will not be available.
Select option System, SFP Configuration to display the SFP Configuration page:
This page contains a single user selectable attribute ‘Data Port Ethernet Media Type To
Use’. This attribute has three options:
• ‘Auto Select (Fiber Preference)’ means that if a supported SFP module is present
and is working, and the optical carrier is present, the Ethernet service connects
through fiber and the copper data port is not used. If the fiber link fails or loses the
carrier signal, the Ethernet service falls back to the copper LAN connection.
• ‘Copper Media Only’ means that the Ethernet service connects through the copper
port only and the Fiber SFP interface is disabled.
• ‘Fiber Media Only’ means that the Ethernet service connects through the Fiber SFP
interface only and the copper port is disabled.
The remaining attributes contain information read from the SFP optical module.

o If SFP Configuration is not available: switch off the power to the wireless unit;
remove and then replace the SFP module; switch the unit back on and confirm
that the SFP Configuration menu is now available.
o If SFP Configuration is available: check the Ethernet Link Status attribute on
the System Status page to see if it indicates a fault.
• Trying swapping the transmit and receive fibers
• Remove and remake both ends of the fiber connection, ensuring that is no dust or
other debris contaminating the connections.
License key is incorrect
• If the license key which you have is incorrect then contact your distributor or
reseller.
Alarms
An SFP is installed but has been disabled because your license key does not
include Fiber support
• This alarm indicates that the license key entered into the PTP 600 unit is invalid.
No Fiber link established but no LOS (i.e. an optical carrier is detected).
Broken TX Fiber or link disabled at Fiber link partner?
• This alarm indicates that a signal is being received over the fiber interface but the
transmit fiber is broken or the receiver at the far end is disabled.
