Quick StartD ESCRIPTIONThis guide includes the following products:The Small Form-Factor Pluggable (SFP) 3.125 Bidirectional(BIDI) 10 km plugs into ADTRAN equipment designed to acceptSFPs. Installed into an appropriate host unit, the BIDI SFPprovides a 3.125G optical interface to the supporting system.g NOTEThe 1442821F1 and 1442821F2 must be deployed as pairs ateach end of the system. The 1442821F1 must be connected tothe 1442821F2 at the other end of the fiber.INSTALLATIONTo install the SFP into an appropriate module, complete thefollowing steps:1. Inspect the SFP. If damaged, file a claim with the carrier andthen contact ADTRAN Customer Service.2. Do not remove the protective end cap from the SFP until thefiber optic cable is ready to be connected.3. Insert the SFP into the SFP cage on the module. Ensure themanufacturer’s label on the SFP is facing upward for correctinstallation.4. Slide the SFP all the way into the receptacle until there is anaudible “click.”f CAUTION!Due to compliance certification requirements, use only SFPssupplied by ADTRAN. ADTRAN cannot certify system integritywith other SFPs.w NOTICEThe latch on the SFP is used to remove the SFP from the cage onthe circuit card.Part Number Description1442821F1 SFP 3.125G BIDI 1310/1550 NM1442821F2 SFP 3.125G BIDI 1550/1310 NMOPERATIONAL S PECIFICATIONSGeneral■ Module type: SFP■ Fiber/Copper: Fiber♦ SM/MM: Single Mode♦ Single/Dual-fiber: Single Fiber■ Optical Connector: LC■ Applications: OC-48/STM-16; 1.0G, 3.125G■ Distance: 10 km■ Digital Diagnostic Monitoring: SFF- 8472 and SFF-8047iCompliantOptical■ Optical Budget: 13 dB■ Transmitter♦ Laser Diode Type: DFB♦ Tx Central Wavelength: 1310 nm♦ Tx Output optical power: –5.0 dBm to +0.0 dBm♦ Tx Spectral width: 1 nm♦ SMSR: 30 dB♦ Extinction Ratio: 8.2 dB■ Receiver♦ Rx Type: PIN♦ Rx Central wavelength: 1550 nm♦ Input optical power: +0 dBm to –18 dBm♦ Receiver Overload: +0 dBm♦ Receiver Sensitivity: –18 dBmEnvironmental■ Extended Support:♦ Operational temperature range: –40°C to +70°C♦ Case temperature hardened range: –40°C to +85°C♦ Storage temperature range: –40°C to +85°C♦ Relative humidity to 5 to 95%, noncondensingSmall Form-Factor PluggableSFP3.125G BIDI 10 kmFebruary 201761442821F1-13A
