BBG-SFP-SXH
3G/HD/SD-SDI / ASI Reconfigurable Video SFP
Transceiver with Externally-Accessible SFP
Module
The BBG-SFP-SXH Coax/Fiber Transceiver (hereinafter called "BlueBox™ SFP-SXH")
provides a small "throwdown" package that has an external SFP cage which supports
numerous SFP choices that provide single or dual-channel IP-2022/2110 encapsulation or de-
encapsulation conversions to and from SDI and uncompressed IP video. An SDI output, as
well as convenience HDMI and analog audio downmix pair monitor audio outputs are also
provided. IP interfaces are facilitated via an SFP optical module (see Specifications).
Conversion schemes (encap, de-encap, etc.) are facilitated by the factory-installed software
loaded on BlueBox™ SFP-SXH at time of order (see BlueBox™ SFP-SXH Configurations).
The unit receives its DC power from either connecting its USB port to associated equipment,
or by the supplied AC adapter (dual-sourcing provides redundancy).
Connecting BlueBox™ SFP-SXH
1 Connect BlueBox™ SFP-SXH to DC power using the supplied AC adapter or USB
connection.
2. Remove any protective caps on fiber cables and/or input receptacles. Connect BNC Coax
input/outputs and Fiber input/outputs to desired input/output connectors. This provides the
basic conversion connections. Unused connections do not require termination.

CLASS 1 LASER PRODUCT
IEC 60825-1:2007
Caution - INVISIBLE LASER RADIATION. AVOID EXPOSURE TO THE
BEAM.
Status Indicator
BlueBox™ SFP-SXH has Status LEDs (one LED for the fiber input channel and one for the
coax input channel) on the side of the unit which function as follows:
• Solid Green – Recognized SDI present.
• Green Flash – No SDI present, or not recognized as SDI.
Note: SFP type and form (-EO, -OE, -
EOOE) is determined by BBG-SFP-SXH
model ordered. See Specifications.

Configure Select Using DIP Switch Bank
BlueBox™ SFP-SXH can be used in a local control mode using DIP switches to configure
settings, or via USB remote control. The USB remote also provides an optical Tx power meter
for Tx confidence assessment. Refer to diagram on unit label for switch positions.
• If using DIP switch control, make certain switch SW1 is set to ON. USB remote control
is locked out in this mode.
• If using USB remote control, make certain switch SW1 is set to OFF. DIP switch local
control is locked out in this mode.
Input Routing Select Switches
BlueBox™ SFP-SXH DIP switches SW2 and SW3 allow for selecting from either SDI coaxial
input via SDI I/O or SFP input via SFP I/O as shown below and on rear label on unit. The
Failover choices allow selecting from either SDI or SFP as the Primary input to be used (Pri),
with failover to Secondary (Sec) as shown.
Audio De-Embed Select Switches
BlueBox™ SFP-SXH DIP switches SW4 thru SW6 allow for selecting de-embed to be applied
to the HDMI output as well as stereo downmix to the convenience analog audio
AN-AUD L/R OUT TRS 3.5mm stereo connector using DIP switch bank as shown below and
on the unit label.
Unbalanced Audio Levels and This Device
The unbalanced audio outputs on this device (available on the AN-AUD L/R OUT TRS 3.5mm stereo
connector) correspond to 2.2 Vrms output when sourced from a unity-gain 0 dBFS digital sine-wave source.
Consumer audio is specified in dBV with a nominal (or recording) level of -10 dBV. The 2 Vrms maximum
output level corresponds to +6 dBV. The unbalanced analog outputs on this device allow for 16 dB of
headroom above the nominal -10 dBV consumer level ("headroom" is the range between the maximum and
nominal audio levels). Professional balanced analog audio levels in the US typically use a +4 dBu nominal
level with 20 dB of headroom (-20 dBFS). The maximum level for balanced analog interfaces is +24 dBu.
The headroom difference between consumer and professional audio will result in a lower consumer level
when converting from professional balanced analog audio. For example, if pro level analog audio is
received and transmitted via AES or embedded SDI to a receiver converting to unbalanced analog audio,
the output will be 4 dB lower, with a nominal level of -14 dBV.
Channel Line-Up of HDMI vs. Standard SDI Conventions
To maintain conformance with CEA-861D HDMI audio channel line-up specifications and industry standard
SDI convention, this device has DIP switch SW7 that selects audio line-up on the HDMI output as listed
below (SDI line-up is always per SDI convention)
