Product Specifications 10Gb/s, 1310nm 40km, Single Mode, Multi-Rate SFP+ Transceiver FTLX1772M3BCL PRODUCT FEATURES Hot-pluggable SFP+ footprint 17dB optical link budget for up to (1) 40km over G.652 single mode fiber Supports 6.144, 8.5G and from 9.83 to 11.3 Gb/s bit rates Un-cooled 1310nm DFB laser Receiver limiting electrical interface APPLICATIONS Power dissipation < 1.5W 6.144G/9.83G CPRI -5C to 75C temperature range 8.5Gb/s Fibre Channel RoHS-6 compliant (lead-free) 10G NRZ SONET, SDH Single 3.3V power supply 10G Ethernet and Fibre Channel Duplex LC connector G.709 OTN FEC bit rates Built-in digital diagnostic functions Finisars FTLX1772M3BCL 10Gb/s Pluggable SFP+ transceivers are compliant with 1 2 SFF-8431 and SFF-8432 , and support 10G SONET, SDH, OTN, IEEE 802.3ae, 8x/10x Fibre Channel and 6.144G/9.83 CPRI. The transceivers have higher optical transmit power and better receiver sensitivity than 1310nm 10GBASE-LR and OC-192 SR-1 transceivers, and they support an optical link budget of 17dB, to compensate for the (1) higher fiber attenuation loss at 1310nm over 40km of G.652 single mode fiber. Digital diagnostics functions are available via a 2-wire serial interface, as specified in 6 SFF-8472 . The FTLX1772M3BCL transceivers utilize internal transmitter and receiver re-timer ICs for SONET/SDH jitter compliance and to enhance host cards signal integrity. The optical transceiver is compliant per the RoHS Directive 2011/65/EU. See 7,8 Finisar Application Note AN-2038 for more details .

T is an open collector/drain output, which should be pulled up with a 4.7k 10k Ohms resistor on FAULT the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high output indicates a transmitter fault caused by either the TX bias current or the TX output power exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the output is pulled to <0.8V. 3. Laser output disabled on T >2.0V or open, enabled on T <0.8V. DIS DIS 4. Internally pulled down per SFF-8431 Rev 2.0. See Sec. X for the logic table to use for the internal CDRs locking modes. 5. LOS is open collector output. Should be pulled up with 4.7k 10k on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation logic 1 indicates loss of signal.
