Product Information
Small Form Factor Transceiver
The small form factor transceiver is an integrated duplex data link for bi-directional communications over
multimode or single mode optical fiber. Each small form factor transceiver consists of a transmitter and
receiver optical subassembly. The transmitter subassembly contains a semiconductor laser emitting in
the wavelength range of 770 to 860 nanometers for shortwave length small form factor transceivers and
1270 to 1355 nanometers for long wavelength small form factor transceivers. For non-OFC links, the
optical power from the laser transmitter is controlled and maintained at a lower power level. The power
emitted from either an open fiber or open laser transmitter is guaranteed to be below the Class 1 limit.
Class 1 laser products are not considered hazardous. No user maintenance, service operations or
adjustments can be performed the small form factor transceiver.

Usage Restrictions
Failure to comply with these usage restrictions may result in incorrect operation of the system and could
possible lead to points of access that may emit laser radiation levels above the Class 1 limits established
in the U. S. by the DHHS and within Europe by EN60825-1/EN60825-2.

Short wavelength and long wavelength small form factor transceivers allow normal data transmission on
the optical link when they are connected to another compatible laser product. Short wavelength and long
wavelength small form factor transceivers embedded in Emulex host adapter are non-OFC. For non-
OFC links, a compatible laser device must be non-OFC and certified as a Class 1 laser product.

OFC links, a compatible laser device must be non-OFC and certified as a Class 1 laser product.
Any system level product that incorporates the small form factor transceivers must provide power supply
protection that guarantees a voltage of 5.0 volts or less at the small form factor transceivers. The
functional power supply range of the small form factor transceivers product is specified as 3.135 to
3.465V typically. Operation outside of this range may degrade the performance and lifetime of the
transceiver. The transceiver will remain operational with laser emissions below Class 1 limits provided
the power supply level at the adapter remains at or below 5.0 volts. If the power supply level rises above
5.0 volts, the small form factor transceiver cannot be guaranteed to operate correctly and could result in
laser emissions that may exceed Class 1 limits.

System Level Certification
All host adapters containing embedded small form factor transceivers are certified as Class 1 laser
products within the U.S. and Class 1 laser component assemblies outside of the U.S. Manufacturers of
products properly incorporating the small form factor transceiver do not need to recertify their product for
laser safety. The procedure for full system certification is therefore identical to that used for any other
electronic system. When applying for system level certification to electronic standards such as IEC950,
the regulatory engineers may want to see the DHHS and European conformity labeling on the small form
products within the U.S. and Class 1 laser component assemblies outside of the U.S. Manufacturers of
