40G QSFP+ Light Module OTQ-40G-PSM4
OTQ-40G-XX series single mode QSFP+ transceiver is designed for single-mode fiber optical data communications such as 40GBASE-LR4. The transceiver consists of two sections: The transmitter section consists of four directly modulated uncooled CWDM 4- 1271, 1291, 1311, and 1331 nm DFB lasers and four drivers. The receiver section incorporates four PIN photodiodes integrated with four trans-impedance preamplifiers (TIA) and four limiting post-amplifier ICs. The module is with the QSFP+ 38-pin connector to allow hot plug capability. The internally ac coupled high speed serial I/O simplifies interfacing to external circuitry. Only single 3.3V power supply is needed. A serial EEPROM in the transceiver allows the user to access transceiver digital diagnostic monitoring and configuration data via the 2-wire QSFP+ Management Interface. This interface uses a single address, A0h, with a memory map divided into a lower and upper area. Basic digital diagnostic data is held in the lower area while specific data is held in a series of tables in the high memory area. Up to 10.3125 Gbps bi-directional data links per lane Compliant with SFF-8436 QSFP+ MSA Complaint with IEEE 802.3ba 40GBASE-LR4 Hot pluggable electrical interface Link length up to 10km with SMF Uncooled CWDM 4-wavelength DFB LDs: 1271, 1291, 1311, and 1331 nm 2-Wire interface for integrated digital diagnostic monitoring Power consumption < 3.5W Single +3.3 V power supply Temperature range support 0°C to +70°C RoHS compliant
