Using the OSP SFP+ Module

By default, OSP SFP+ is already inserted into all Kramer optical products.
Kramer offers both duplex and simplex transceiver modules as specified below.
Duplex (dual-fiber strand) modules:
•
OSP-MM1: Optical MM 850nm 10G SFP+ Transceiver (usually included in the package).
•
OSP-SM10: Optical SM 1310nm 10G SFP+ Transceiver (can be purchased separately).
Simplex (single-fiber strand) module:
•
OSP-SM10S: Optical SFP+ Transceiver Pair over 10G 1270/1330nm Simplex SM Fiber (can be
purchased separately).

Replacing the OSP SFP+ Modules

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.
When replacing the optical transceivers, use compatible SFP+ optical transceiver
modules on both extender paired end-point units.

Notes on Connecting the OSP SFP+ Modules

OSP-MM1 and
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-SM10 modules, such as the optical patch panel and bulk cables illustrated
below, 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.
