Product Information

Small Form Factor Pluggable Transceiver

The small form factor pluggable 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 small form factor pluggable short-wavelength

transceivers and 1270 to 1355 nanometers for long wavelength small form factor

pluggable transceivers. For non-optical fiber cable (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.

Any system level product that incorporates the small form factor transceivers must

provide power supply protection that guarantees a voltage of 4.0 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 3.465 Volts 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 4.0 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.
