10G SFP+ LR 1310 nm 10 km

ASCENT’s SFPP-ATLP-31-10 Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the 1310nm FP laser and the PIN photo-detector. The module data link up to 10 km using 9/125 µm single-mode fiber. The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also can disable the module via I2C. Tx Fault is provided to indicate that degradation of the laser. Loss Of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access.

•      Support data rate up to 11.3Gb/s

•      Hot-Pluggable SFP Footprint and Single LC Connector

•      Up to 10km reach for G.652 SMF

•      1310nm DFB laser and PIN receiver

•      Temperature Range:

      Commercial: 0°C to +70°C

      Industrial: -40°C to +85°C

•      Compliant with SFP-8431

•      Compliant with SFP-8432

•      Compliant with SFP-8472

•      Compliant with IEEE802.3ae

Note:
   The transceivers provide serial ID memory contents and diagnostic information about the present operating conditions by the 2-wire serial interface (SCL, SDA).
   The diagnostic information with internal calibration or external calibration all are implemented, including received power monitoring, transmitted power monitoring, bias current monitoring, supply voltage             monitoring and temperature monitoring.
