691 - Overview
3 Overview
691 is a high-performance HDBaseT 2.0 fiber transmitter 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. 691 converts all the input
signals into the transmitted HDBaseT 2.0 signal over fiber optic cable. The
extended line receiver, such as Kramer 692, converts the HDBaseT 2.0 signal
back to 4K60Hz (4:2:0) HDMI, USB 2.0, Ethernet, RS-232, IR and stereo audio
output signals.
691 extends video signals to up to 33km (20.5 miles) over single-mode fiber at up
to 4K@60Hz (4:2:0) resolution.
The 691 transmitter features:
High performance standard fiber extender –HDBaseT 2.0 fiber transmitter for
providing ultra-reach signals over either multi-mode or single-mode optical
fiber infrastructures, using Kramer pluggable OSP SFP+ units. 691 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 691 product, use only
Kramer's certified high-performance OSP SFP+ pluggable optical
modules:
OSP-MM1: Optical MM 850nm 10G SFP+ Transceiver
OSP-SM10: Optical SM 1310nm 10G SFP+ Transceiver
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 –HDMI 2.0 and HDCP 1.4 compliant. Supports deep
color, x.v.Color™, lip sync, HDMI uncompressed audio channels, Dolby
TrueHD, DTS-HD, 2K, 4K, and 3D. EDID and CEC signals are passed
through from the source to the display.

691 - Overview

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 their 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 embedding (Adding) –A selectable analog unbalanced stereo audio
input is converted into a digital signal and added (embedded) to the
transmitted HDMI signal, replacing the embedded HDMI audio input signal.
This enables embedding a selectable audio source over HDMI. For example,
a presenter can display a video clip and temporarily override the audio of the
source media with another audio source, such as from a microphone.
Cost-effective maintenance –Status LED indicators for the HDMI input and
HDBT output link facilitate easy local troubleshooting. Remote device
management via built-in web UI and RS-232 connection enable simple
device maintenance. Kramer Network support provides remote device and
network management. Local and remote firmware upgrade via mini-USB,
RS-232 or Ethernet connection and the K-Upload tool ensure lasting,
field-proven deployment.
Easy installation –Half 19” 1U rack mountable fan-less enclosure enables
side-by-side mounting of 2 units in a 1U rack space.

5.1 Using the OSP SFP+ Module
Before connecting the 691 to an optical receiver, you need to insert the same type
of SFP+ transceiver both into the SFP+ opening on the 691 and the compatible
receiver.
Two types of Kramer SFP+ optical transceiver modules are available:
OSP-MM1: Optical MM 850nm 10G SFP+ Transceiver
OSP-SM10: Optical SM 1310nm 10G SFP+ Transceiver
Before deciding which transceiver module to use, 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 691
transmitter and the receiver (for example 692).
The following table defines various typical Fiber cable characteristics, used for
optical reach evaluation:

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 12):
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.

14
691 - Connecting the 691 HDBT 2.0 Optical Transmitter
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 12):
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
To insert the SFP+ module:
1. Make sure the bail is pushed up, in the closed position.
2. Insert the OSP-MM1/OSP-SM10 into the IN OUT SFP+ slot and push it in
until it clicks.
Figure 6: Inserting the Transceiver Module
