SFP-10GD-LR

Datasheet 10 Gbps 10 km Single-Mode SFP+ Transceiver SFP-10GD-LR Features Hot-pluggable SFP+ footprint Supports 9.95 to 10.52 Gbps bit rates Power dissipation < 1W RoHS-6 compliant (lead-free) Commercial temperature range -5°C to 70°C Single 3.3 V power supply Maximum link length of 10 km Uncooled 1310 nm DFB laser Receiver limiting electrical interface Duplex LC connector Built-in digital diagnostic functions MRV’s SFP-10GD-LR 10 Gbps Enhanced Small Form Factor Pluggable SFP+ transceivers are designed for use in 10-Gigabit Ethernet and 10 Gigabit Fibre Channel links up to 10km over single-mode fiber. They are compliant with SFF-8431, SFF-8432 and IEEE 802.3ae 10GBASE-LR/LW. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. The SFP-10GD-LR is a “limiting module”, i.e., it employs a limiting receiver. Host board designers using an EDC PHY IC should follow the IC manufacturer’s recommended settings for interoperating the host-board EDC PHY with a limiting receiver SFP+ module. The transceiver is RoHS compliant and lead free per Directive 2002/95/EC.

Use of four 1’s and four 0’s in sequence in the PRBS 9 is an acceptable alternative. SFF-8431 Rev 2.1 LOS is an open collector output. Should be pulled up with 4.7kΩ – 10kΩ on the host board. Normal operation is logic 0; loss of signal is logic 1. See section 2.8.3 of SFF-8431. Rev 2.1 The SFP-10GD-LR is a “limiting module”, i.e., it employs a limiting receiver.

TFAULT is an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on 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 2.0V or open, enabled on TDIS
