2405OE-HD SMPTE 292M Re-Clocking Fiber to Electrical Converter
Revision 1.2 2405OE-HD-1
1. OVERVIEW
The 2405OE-HD Fiber to Electrical converter provides an economical method of converting incoming
optical distribution for SMPTE 292M (1.5 Gb/s) HDTV serial digital signals to in-plant coaxial distribution.
The companion 2405EO-HD Electrical to Fiber converter facilitates conversion from coaxial distribution at
the source. The converter features one optical input with two re-clocked serial digital outputs. The
2405OE-HD has been designed to be used primarily as a reclocking 1.5Gb/s distribution amplifier,
however, it can also be used as a non-reclocking SMPTE 310M (19.4 Mb/s), DVB-ASI, or SMPTE 259M
(143 to 540 Mb/s) distribution product.
Features:
• Reclocking mode for SMPTE 292M (1.5 Gb/s) signals
• Non-reclock mode for SMPTE 310M (19.4 Mb/s), SMPTE 259M (143 to 540 Mb/s) or DVB-ASI, or
most other bit rates less than 1.5 Gb/s
• Independent isolated output drivers to ensure no cross channel loading effects and maintain polarity
from input to output for DVB-ASI applications
• Operation with multi-mode or single-mode fiber
• SC/PC, ST/PC or FC/PC connector options
• Comprehensive signal, laser and modules status indicator LEDs
• Low power +12 VDC operation
*Note: Non-reclock Mode will operate 19.4 Mb/s to 1.5 Gb/s

2. INSTALLATION
The 2405EO-HD is a compact module that has two BNC connectors and one SC/PC (shown), ST/PC or
FC/PC optical connector.
Figure 2-1: 2405EO-HD Module
HD INPUT: There is a SC/PC (shown), ST/PC or FC/PC female connector for optical 10-bit serial digital
video signals compatible with the SMPTE 292M standard. The 2405OE-HD can also be used
in non-reclock mode with SMPTE 310M (19.4 Mb/s), SMPTE 259M (143 to 540 Mb/s) or
DVB-ASI, or any other signal with bit rate less than 1.5 Gb/s. See section 5.1 for information
on operating the module in non-reclock mode.
HD OUTPUT: There are two BNC connectors with reclocked serial component video outputs, compatible
with the SMPTE 292M standard. In non-reclock mode these outputs contain an equalized copy
of the input signal.
The 2405OE-HD comes with an auto-ranging DC voltage adapter that automatically senses the
input voltage. Power should be applied by connecting a 3-wire grounding type power supply
cord to the power entry module on the DC voltage adapter. The power cord should be
minimum 18 AWG wire size; type SST marked VW-1, maximum 2.5 m in length. The DC cable
of the voltage adapter should be connected to the DC power jack on the rear panel. A green
LED located beside the power connector will be illuminated when there is power applied to the
2430DAC-HD.

2.1. CARE AND HANDLING OF OPTICAL FIBER
2.1.1. Safety
Never look directly into an optical fiber. Non-reversible damage to the eye can
occur in a matter of milliseconds.
The laser modules used in the Evertz fiber optic modules are Class I, with a maximum output power of
2mW, and wavelengths of either 1310 nm or 1470 to 1610 nm.
2.1.2. Handling And Connecting Fibers
"Never touch the end face of an optical fiber.
The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore
care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. Evertz
recommends that you maintain a minimum bending radius of 3 cm to avoid fiber-bending loss that will
decrease the maximum attainable distance of the fiber cable. The Evertz fiber optic modules come with
cable lockout devices, to prevent the user from damaging the fiber by installing a module into a slot in the
frame that does not have a suitable I/O module. For further information about care and handling of fiber
optic cable see section 3 of this manual binder.

6. FIBER OPTICS SYSTEM DESIGN
Fiber optics is best known for its applications in the telephone industry, even though it is widely used in
video and television systems. In television systems they typically send signals between two locations or
distribute the same signal to many destinations.
Traditional video distribution systems have used coaxial copper cabling. Fiber optic cable provides many
advantages over traditional copper wire:
• Lower cable losses allow longer distances without distribution amplifiers
• Ability to carry higher data rate signals
• Improved signal quality
• Immunity from electro-magnetic radiation and Lightning
• Light Weight
The crucial difference between fiber optic distribution systems and coaxial cable systems is that signals
are transmitted as light. The two key elements of optical fiber are its core and its cladding. The core is the
inner part of the fiber, through which the light is guided. The cladding surrounds the core completely. The
refractive property of the cladding is higher than that of the core, so light in the core that strikes the
boundary with the cladding at a glancing angle, is totally reflected back into the core. The boundary of the
core and cladding acts like a “cylindrical mirror”, causing the core to act as a light pipe.

Figure 6-1: Components of a Fiber Optic Transmission System
The role of an optical transmitter is to convert an electrical data signal into an equivalent optical power
waveform and couple it into an optical fiber. The role of the optical fiber is to convey the light from the
source to the destination with the minimal amount of signal loss. The role of the optical receiver is to
convert the optical power waveform back into an equivalent electrical data signal.

6.1. SYSTEM DESIGN PARAMETERS
6.1.1. Electrical to Optical Parameters
In optical output devices, the main design parameters that are important are the launched output power,
the wavelength and the linewidth. Launch power and wavelength are always important in system designs.
Line width is usually important only in high definition applications.
6.1.1.1. Transmitter Output Launch Power
The launched output power tells us the maximum power available at the optical transmitter. Table 6-1
indicates the launched output power available on current Evertz EO modules.

Table 6-1: Launch Power
6.1.1.2. Wavelength
The wavelength of the optical signal determines the cable loss window within which the system will
operate.
The Loss versus Wavelength graph in Figure 6-2 shows that at 1310nm the cable loss is 0.40dB/km and
at 1550nm the loss is 0.30dB/km.

6.1.1.3. Linewidth
The linewidth is a measure of the laser’s spectral purity, and determines the jitter penalty (how much jitter
gets added to the signal). Linewidth is important in HD applications because the additional jitter penalty is
significant compared to the bit period. In standard definition video applications linewidth is usually not a
problem because the signal will lose too much power before it can go far enough for jitter to be a problem.
At 1310nm the jitter penalty is approximately 2.5psec/km of fiber /nm of linewidth. At 1550nm the jitter
penalty is approximately 17ps/km of fiber/nm of linewidth.

In Optical input devices, the main design parameters that are important are the maximum power before
overload and the minimum power before errors (Sensitivity). Table 6-2 indicates the maximum power and
sensitivity on current Evertz OE modules.

In passive optical modules, the main design parameter that is important is the loss through the passive
device. Table 6-3 indicates the power loss on current Evertz 7705 series passive fiber modules.

6.2. DESIGN EXAMPLES
6.2.1. Standard Definition 2 km Link
2 km x 0.4 = 0.8 dB
EO13 7705OE
Using the 2405EO3F as the transmitter.
Launch Power = -7.5 dBm
Connector Loss = 2 x 1 -2.0 dB
Fiber Loss = 2 x 0.4 -0.8 dB
Safety Margin = -2.0 dB
Power at receiver –12.3 dBm
The 2405OE has a listed sensitivity of –30 dBm, which is lower than –12.3 dBm so we can implement the
system with no problems, at least with respect to power availability.
Next we need to check the jitter penalty. The system jitter-penalty = 2.5 ps/ x 2 km x 5 nm = 25 ps. So by
going through 2km of fiber, we add 25ps of jitter under the worst conditions (under the best conditions we
would add 2ps total). The standard definition video bit period is 3.7 ns; so if the maximum jitter penalty is
20% or 740 ps., then the added jitter for this system is insignificant.
When would jitter-penalty be a problem? For 1310 nm wavelengths, the cable length where the jitter
penalty becomes significant is calculated as: 740 ps divided by 2.5 ps/km/nm divided by 5 nm = 60 Km
(worst case), or 600 Km (normal condition). At 60 Km cable length the cable loss is 60 x 0.4 = 24 dB. So
the power into the receiver would be: – 6 dBm – 24 dB = – 30 dBm. This is equal to the published
specification of -30 dBm but leaves no margin for connector or other losses. The jitter penalty at 1550 nm
for standard definition video is calculated as: 740 divided by 17 divided by 0.8 = 54 Km (worst case). At
54 Km cable length the cable loss is 54 x 0.3 = 16.2 dB. So the power into the receiver would be:
- 0 dBm – 16.2 dB = - 16.2 dBm. This is above the published specification of -30 dBm, so added jitter may
become significant on cable lengths approaching 54 Km at 1550 nm.

2405OE-HD-12 Revision 1.2
WDM Loss = 2 x 4 -8.0 dB
Power at receiver –29.5 dBm
For the 1310 nm path the power available at the receiver is very close to the receiver input sensitivity of
-30 dBm. This calculation assumes the worst case connector losses, and a safety margin of 2 dB. In
practice, the actual system may be viable, but we should assemble the system including the connectors
and actually measure the available power at the receiver to determine the viability. For the 1550 nm path
the transmitter launch power is greater and the cable loss is less, so the resulting system design is OK for
power loss.
6.3. CALCULATING THE OPTICAL SYSTEM POWER BUDGET
Given a specific optical transmitter and receiver pair, the most important question concerning a system
designer or integrator is the maximum possible link length. Here is a worksheet that simplifies this
calculation. The specific receiver/transmitter parameters used in the worksheet vary depending on the
specific module being used. Consult the specifications in the respective chapters for the modules to get
the correct values for the worksheet.
Transmitter Launch Power................................................................................ _______ dBm
Receiver Sensitivity........................................................................................ - _______ dBm
Maximum Allowable Loss: ........................................................................ = ________ dB
Fiber Loss: † ____km X Attenuation: _______dB/km........................... ________ dB
Connector Loss: ‡ _____Connectors X Loss/Connector _______ dB ..... + ________ dB
Passive Device Attenuation.......................................................................... + ________ dB
Safety Margin................................................................................................ + ________ dB
Total System Loss:..................................................................................... = ________ dB
If the Total System Loss < Maximum Allowable loss, then the system is viable. A conservative industry
standard for the safety margin is 2dB, and 1 dB per connector. However, these may vary and are usually
determined by the system integrator/system engineer.
† Attenuation over Corning SMF 28 Single Mode Fiber: 0.3 dB/km @ 1550 nm, 0.4 dB/km @ 1310 nm
‡ If 62.5µm multimode fiber is used then 2dB must be added to the connector loss to account for receiver
and cable fiber diameter mismatch.

6.4. CARE AND HANDLING OF OPTICAL FIBER
6.4.1. Safety
Never look directly into an optical fiber.Non-reversible damage to the eye can occur in a matter of
milliseconds. The laser modules used in Evertz fiber optic products are all CLASS I, with a maximum
output power of 2mW, and wavelengths of either 1310 nm or 14750 nm to 1610 nm.
6.4.2. Handling And Connecting Fibers
"Never touch the end face of an optical fiber.
The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore
care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. Evertz
recommends that you maintain a minimum bending radius of 3 cm to avoid fiber bending loss that will
decrease the maximum attainable distance of the fiber cable. Evertz fiber modules come with cable
lockout devices, to prevent the user from damaging the fiber by installing a module into a slot in the frame
that does not have a suitable I/O module.
Dust particles on the ends of the optical fiber greatly increase the signal loss at interconnections, and
large dust particles can even obscure light transmission altogether. To minimize the effects of dust
contamination at the interconnections, the fiber should be cleaned each time it is mated or unmated. When
using interconnection housings to mate two optical fibers it is good practice to remove dust particles from
the housing assembly with a blast of dry air. Whenever a fiber is unmated it must be covered immediately.
Most fiber manufacturers provide a plastic boot that fits over the ferrule body for this purpose.
Fiber interconnections must be made securely. The Evertz fiber optical transmitters and receivers come
with SC interconnection housings built into the module. With this style of connector, the fiber assembly
and the housing assembly can only be connected in one way and with very good repeatability. The rear
fiber interconnect panel that is provided with each module can be ordered with optional SC/PC, ST/PC or
FC/PC connectors. The customer is required to provide the optical fiber with the correct connectors to
connect the modules together. SC/PC, ST/PC and FC/PC interconnection housing and connectors as well
as adapters are industry standards with many available sources.
6.4.3. Making Sure The Optical Fibers Are Clean
It is very important to ensure that optical fibers are clean before mating and after unmating. You should
have received a pre-moistened tissue with the optical module. Remove this tissue from its package and
wipe the end of the fiber connector before mating it to the module.
