RSPD-10GD80-T50
10Gb/s 80km DWDM Tunable SFP Transceiver

Hot Pluggable, Duplex LC, 50GHz ITU-T-T, DWDM Tunable&APD, Single mode

Description:

FIBERWDM’ RSPD-10GD80-T50 Small Form Factor 10Gb/s (SFP) transceivers are compliant with the current SFP Multi-Source Agreement (MSA) Specification. The high performance cooled DWDM TUNABLE transmitter and high sensitivity APD receiver provide superior performance for SONET/SDH, 10G FC and Ethernet applications up to 80km optical links.

The SFP+ Module compliants with SFF-8431, SFF-8432 and IEEE 802.3ae 10GBASE-ZR. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472.

The fully SFP compliant form factor provides hot pluggability, easy optical port upgrades and low EMI emission.

SFP Module EEPROM Information and Management

The SFP modules implement the 2-wire serial communication protocol as defined in the SFP -8472. The serial ID information of the SFP modules and Digital Diagnostic Monitor parameters can be accessed through the I2C interface at address A0h and A2h. The memory is mapped in Table 1. Detailed ID information (A0h) is listed in Table 2. And the DDM specification at address A2h. For more details of the memory map and byte definitions, please refer to the SFF-8472, “Digital Diagnostic Monitoring Interface for Optical Transceivers”. The DDM parameters have been internally calibrated.
