692 - Overview
3 Overview
692 is a high-performance HDBaseT 2.0 fiber receiver for ultra-reach extension of
4K60Hz (4:2:0) HDMI, USB 2.0, Ethernet, RS-232, IR and stereo audio signals
over either multi-mode or single-mode fiber optic cable. 692 converts the
HDBaseT 2.0 fiber optics signal received from an extended line transmitter, such
as Kramer 691, back into 4K60Hz (4:2:0) HDMI, USB 2.0, Ethernet, RS-232, IR
and stereo audio output signals.
692 extends video signals to up to 33km (20.5 miles) over single-mode fiber at up
to 4K@60Hz (4:2:0) resolution. 692 includes a multimode OSP+ transceiver
(Kramer OSP-MM1), but can be used with a single mode OSP+ transceiver and
fiber as well.
The 692 receiver features:
•High performance standard fiber extender –HDBaseT 2.0 fiber receiver for
providing ultra-reach signals over either multi-mode or single-mode optical
fiber infrastructures, using Kramer pluggable OSP SFP+ units. 692 is a
standard fiber extender that can be connected to any market-available
HDBaseT-compliant extension product.
To ensure Kramer support and warranty of the 692 product, use only
Kramer's certified high-performance OSP SFP+ pluggable optical
modules:
OSP-MM1: Optical MM 850nm 10G SFP+ Transceiver (included).
OSP-SM10: Optical SM 1310nm 10G SFP+ Transceiver (can be
purchased separately).
For optimum extension reach and performance, use Kramer's OSP SFP+
units and recommended Kramer cables. Non-Kramer cables may not
reach these ranges.
Note that the maximum transmission reach is typical and may vary
depending on fiber cables performance, signal resolution, connectors and
splicing optical losses, modal or chromatic dispersion, and similar optical-
related factors.

•HDMI Signal Extension –HDCP 1.4 compliant. Supports deep color,
x.v.Color™, lip sync, HDMI uncompressed audio channels, Dolby TrueHD,
DTS-HD, 2K, 4K, and 3D as specified in HDMI 2.0. EDID and CEC signals
are passed through from the source to the display.
•I-EDIDPro™ Kramer Intelligent EDID Processing™ – Intelligent EDID
handling, processing and pass-through algorithm that ensures Plug and Play
operation for HDMI source and display systems.
•USB Extension –USB 2.0 interface data flows in both directions, allowing
extension of HID (Human Interface Devices) peripheral devices, such as a
mouse or a keyboard. High-bandwidth USB peripheral devices, such as USB
isochronous streaming cameras and audio devices, transfer data
continuously and periodically.
Delivery of the transferred data is not guaranteed by the USB standard
and is subject to both USB and HDBaseT line bandwidth management
limitations. When such devices are connected, check their functionality
to ensure bandwidth limitations are not exceeded.
•Ethernet Extension –Ethernet interface data flows in both directions allowing
extension of up to 100Mbps Ethernet connectivity for LAN communication
and device control.
•Bidirectional RS–232 Extension –Serial interface data flows in both
directions allowing data transmission and device control.
•Bidirectional Infrared Extension –IR interface data flows in both directions
allowing remote control of peripheral devices located at either end of the
extended line.
•Audio De-embedding (Drop-and-Continue) –The transmitted digital audio
signal is extracted from the AV signal (dropped), converted to an analog
signal for transmission to stereo balanced analog audio output, in parallel to
being transmitted (continued) to the HDMI AV output. This enables
high-quality audio playback by routing the audio to external speakers in
parallel to routing the audio to the connected AV acceptor device’s local
speakers (such as TVs with speakers).

5.1 Using the OSP SFP+ Module
By default, OSP-MM1 is inserted in 692. If required, replace the optical
transceiver, you need to insert the same type of SFP+ transceiver both into the
SFP+ opening on the 692 and the compatible transmitter.
Two types of Kramer SFP+ optical transceiver modules are available:
•OSP-MM1: Optical MM 850nm 10G SFP+ Transceiver (included in the
package).
•OSP-SM10: Optical SM 1310nm 10G SFP+ Transceiver (can be purchased
separately).
Before deciding to replace the default SFP+ transceiver, consider the infra-
structure of the installation area, the desired distance, optical loss budget and
typical expected loss.
Use the same type of SFP+ optical transceiver module both on the 692
receiver and the transmitter (for example, 691).

OSP-MM1 and OSP-SM10 modules are designed to be used only with
LC(UPC) blue or LC(PC) white connectors. Using an LC(APC) green
connector with the module causes poor performance and can damage
the module connector.
For all other cable connections that do not connect directly to the
OSP-MM1 or OSP-SM10 modules, such as the optical patch panel and
bulk cables illustrated in Figure 5, we recommend using Angled Physical
Contact (APC) green connectors for improved end-to-end reach
performance.
When using OSP modules consider the following:
•Modules are Class 1 Laser products.
•There may be Invisible laser radiation present.
•Avoid long-term viewing of laser.
•Avoid the use of magnifying viewing aids or instruments (such as
binoculars, telescopes, microscopes and magnifying lenses, but not
spectacles or contact lenses).
•Avoid placing optical devices in the emitted beam that could cause
the concentration of the laser radiation to be increased.

5.1.1 Optical Reach Evaluation
The following examples show how to calculate dB loss during optical signal
transmission over fiber optical infrastructure.
In the optical system layout example, illustrated in Figure 5:
•691 and 692 are connected to a patch panel via 100m patch cords.
•There are 6 connectors and no splices.
Figure 5: System Layout Example for Optical Reach Evaluation
For multi-mode lines (MM OM3 cable category, as defined in the table on page 13):
•Maximum loss budget is: 8.6dB.
•Typical loss per connector is 0.3dB.
•Typical loss for each patch cord (100m) is 0.25dB.
•Fiber optic loss is 2.5 dB/km.
Multi-mode bulk line budget is: 8.6 –(0.3x6 +0.25x2) = 6.3dB.
Evaluated bulk line length is: 6.3/2.5=~2.5km.
For single-mode lines (SM OS1 cable category, as defined in the table on page 13):
•Maximum loss budget is: 11.9dB.
•Typical loss per connector is 0.3dB.
•Typical loss for each patch cord (100m) is 0.1dB.
•Fiber optic loss is 1 dB/km.
Single-mode bulk line loss budget is: 11.9 –(0.3x6 +0.1x2) = 9.9dB.
Evaluated bulk line length is: 9.9/1=~9.9km.

5.1.2 Inserting the SFP+ Module
OSP-MM1 (included in the package) comes inserted in the OUT IN SFP connector
opening of 692 from factory. If you want to replace the OSP-MM1 with a different
SFP_ transceiver, you need to remove the installed transceiver before installing
the new one.
To insert the SFP+ module:
1. Pull the bail out and remove the currently installed transceiver, insert the
protective cap and store in a safe place.
2. Make sure the bail of the new transceiver is pushed up, in the closed
position.
3. Insert the 692 into the IN OUT SFP+ slot and push it in until it clicks.
