Installation Site Install the unit in a place where the following conditions are met: The temperature and the relative humidity of the operating environment must be within the specified limits during operation of the unit. Values specified are applicable to the air inlets of the unit. Condensation may not be present during operation. If the unit is installed in a location subject to large variations of ambient temperature (e.g. in an OB‐van), appropriate precautions must be taken. Unobstructed airflow is essential for proper operation. Ventilation openings of the unit are a functional part of the design and must not be obstructed in any way during operation (e.g. ‐ by objects placed upon them, placement of the unit on a soft surface, or improper installation of the unit within a rack or piece of furniture). The unit must not be unduly exposed to external heat sources (direct sunlight, spot lights). Ambient Temperature Units and systems by FiberPlex are generally designed for an ambient temperature range (i.e. temperature of the incoming air) of 5 °C to 40 °C (41 °F to 104 °F). When rack mounting the units, the following facts must be considered: The permissible ambient temperature range for operation of the semiconductor components is 0 °C to +70 °C (32 °F to 158 °F) (commercial temperature range for operation). The airflow through the installation must allow exhaust air to remain cooler than 70 °C (158 °F) at all times. Average temperature increase of the cooling air shall be about 20 °C (68 °F), allowing for an additional maximum 10 °C increase at the hottest components. If the cooling function of the installation must be monitored (e.g. for fan failure or illumination with spot lamps), the exhaust air temperature must be measured directly above the modules at several places within the enclosure. Grounding and Power Supply Grounding of units with mains supply (Class I equipment) is performed via the protective earth (PE) conductor integrated in three‐pin Phoenix™ connector. Units with battery operation (< 60 V, Class III equipment) must be earthed separately. Grounding the unit is one of the measures for protection against electrical shock hazard (dangerous body currents). Hazardous voltage may not only be caused by defective power supply insulation, but may also be introduced by the connected audio or control cables. This equipment may require the use of a different line cord, attachment plug, or both, depending on the available power source at installation. If the attachment plug needs to be changed, refer servicing to qualified personnel. ...

General Instructions for Inserting and Removing SFP Modules Handling Warnings SFP Modules are static sensitive. To prevent damage from electrostatic discharge (ESD), it is recommended to attach an ESD preventative wrist strap to your wrist and to a bare metal surface when you install or remove an SFP Module. Disconnect all optical or copper cables from SFP Modules prior to installing or removing the SFP Module. Failure to do so could result in damage to the cable, cable connector or the SFP Module itself. Removing and inserting an SFP Module can shorten its useful life, so you should not remove and insert SFP Modules any more often than is absolutely necessary. Protect optical SFP modules by inserting clean dust covers into them after the cables are removed. Be sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another SFP module. Avoid getting dust and other contaminants into the optical ports of your SFP modules, because the optics will not work correctly when obstructed with dust. Identify the Latch Type of the SFP Module SFP Modules have various latching mechanisms to secure them into the SFP Cage of a device. The FiberPlex WDM can support a host of manufacturers and brands of SFP Modules so the user may encounter any number of different latches. Some of these are described below. Bail Clasp Actuator Button The bail clasp SFP module has a clasp The actuator button SFP module includes a button that you that you use to remove or install the SFP push in order to remove the SFP module from a port.

Inserting a Module Attach an ESD‐preventative wrist or ankle strap, following its instructions for use. Disconnect and remove all interface cables from SFP Module. If the SFP Module has a Bail Clasp , close the Bail Clasp before inserting the SFP Module. With the gold finger connector on the bottom and the label on the top, line up the SFP Module with the empty cage and slide it in making sure that it is completely inserted and seated in the cage. Removing a Module Attach an ESD‐ preventative wrist or ankle strap, following its instructions for use. Disconnect and remove all interface cables from SFP Module. Release the latching mechanism. Bail Clasp – Open the bail clasp on the SFP Module with your finger in a downward direction. Actuator Button – Gently press the actuator up (or in) while pulling the body of the SFP Module to release the SFP Module from the cage. Mylar Tab – Pull the tab gently in a straight outward motion until it Actuator Button disengages from the port. Make sure the tab is not twisted when pulling as it may become disconnected from the SFP Module. Slide Tab ‐ With your thumb, push the slide tab on the ...

Serial Configuration Interface The SFP 2‐wire serial interface (MOD_DEF1/MOD_DEF2) provides also digital diagnostic monitoring via the SERIAL CONFIG INTERFACE. The serial interface uses the 2‐wire serial EEPROM protocol defined for the ATMEL AT24C02 family component. The memory is organized as a series of 8‐bit data words that can be addressed individually or sequentially. The 2‐wire serial bus address 1010001X (A2h) is used for SERIAL CONFIG INTERFACE access.

Measurements are calibrated over operating temperature and voltage and should be interpreted as defined below. Alarm and warning threshold values should be interpreted in the same manner as real time 16 bit data. Internally measured temperature The temperature is represented as a 16 bit signed two’s complement value in increments of 1/256°C, yielding a total range of ‐128°C to +128°C. The measured range is limited to the operating recommended conditions. To convert a 16 bit digital value in Celsius, take directly the 16‐bit value and divide it by 256°C. If the result is greater or equal to 128, subtract 256 from the result.

Other Considerations Video Optimization The Society of Motion Picture and Television Engineers, or SMPTE, is a leader in the development of standards for film, television, and other video. The Serial Digital Interface or SDI, was standardized by SMPTE for broadcast quality digital video transmission. Other standards evolved from this original standard, defining Enhanced, High‐definition (HD), 3G‐SDI (1080p) and Ultra High‐definition (UHD), or 4K video (2160p). To help ensure error‐free transmission, the standards include a data scrambler / descrambler to create a high density of transitions in the serial data, making it easier for the receiver to maintain timing. Where an encoding method such as 8B‐10B ensures a minimal sequential run of all ones or zeros, it does so at the cost of a 25% increase in bandwidth requirements. The scrambler / descrambler method does not require this, but as a result there are certain combinations of scrambler state and the next data bits to be scrambled that result in a sequence of up to twenty consecutive ones or zeros. These sequences are referred to as pathological conditions, and are present in specific shades of pink or grey. These pathological conditions may create errors in transmission through typical AC coupled optics, or any other AC coupled interface. Video Enhanced or SMPTE Compliant optics are designed to accept these pathological conditions, allowing the longer sequences of ones or zeros to pass without error. SFP MSA Compliance The SFP Multi‐Source Agreement (MSA) is an agreement that was drafted among competing manufacturers of SFP optical modules. The SFF Committee was formed to oversee the creation and maintenance of these agreements including the SFP MSA designated as INF‐8074i. This agreement describes a mutually agreed upon standard for the form and function of SFP modules. However, not all SFPs produced are MSA compliant. The MSA provides for a transceiver (TX/RX) pinout. Other industries such as broadcast had the need for dual TX and dual RX SFP for unidirectional applications such as video. Naturally, a non‐MSA standard was introduced allocating pinout assignments for dual output and dual input I/O configurations. In addition, the some of the internal serial communication pins were reassigned.
