Specifications
Absolute maximum ratings are those beyond which damage to the device may occur.
Prolonged operation between the operational specifications and absolute maximum ratings is not intended and may cause permanent device degradation.

Notes:
Average launch power, each lane (min) is informative and not the principal indicator of signal strength.
Even if TDECQ < 1.4dB, OMAouter (min) must exceed this value.
Transmitter reflectance is defined looking into the transmitter.
Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with SECQ of 0.9 dB.
Measured with conformance test signal at TP3 for the BER = 2.4x10-4
Single-mode Duplex LC PC to Duplex LC PC Optical Connector
The fiber which connects connector A lane 1 must end at connector B lane 2 at the other end of the link.

Multiple Duplex LC patch cables can be connected in series, but each added connector pair adds reflections in the link which impairs performance.

Regulatory Compliance
The transceiver is a Class 1 laser product. It is certified per the following standards:
|

Agency |
Standard |
|
Laser Eye Safety |
FDA/CDRH |

Handling and Cleaning
The transceiver can be damaged by exposure to current surges and over voltage events. Take care to restrict exposure to the conditions defined in Absolute Maximum Ratings. Observe normal handling precautions for electrostatic discharge-sensitive devices.
The transceiver is shipped with dust caps on both the electrical and the optical port. The cap on the optical port should always be in place when there is no fiber cable connected. The optical connector has a recessed connector surface which is exposed whenever it has no cable nor cap.
Important note 1: Keep both the fiber and transceiver dust caps.
Important note 2: Clean both transceiver receptacle and cable connector prior to insertion of the fiber cable, to prevent contamination from it.
The dust cap ensures that the optics remain clean during transportation. Standard cleaning tools and methods should be used during installation and service. Liquids must not be applied.
Important note 3: 80% of transceiver link problems are related to dirty optical connectors.
