56G 2km QSFP+ PSM4 LC Pigtail Module

QSFP+ PSM4 LC Pigtail

The 106426-00xx is 106426 series LC pigtail module in the QSFP+ form factor with digital diagnostics monitoring functionality (DDM) and control functions. Supporting PSM4 specifications makes it ideally suited for 56G applications where cost effective high port density is needed. It offers four times port density of 56G QSFP+ LC pigtail modules. DDM functionality (alarm and warning features) is integrated into the design via an I2C serial interface per the Multi-Source Agreement (MSA) SFF-8636, Rev. 2.5.

The LC pigtail module supports 56Gbps data rate over four coarse wavelength division multiplexed lanes. The four lanes are at 1310nm wavelength respectively. Each lane transmits and receives data streams at typical rate of 1-14.1Gbps for 56GbE applications. It provides an excellent solution for 56G data transmission over up to 2km single mode fiber. The low power consumption and excellent EMI performance enable system design with high port density. The product is designed and tested in accordance with industry safety standards. The LC pigtail module is Class 1 Laser product per U.S. FDA/CDRH and IEC 60825-1:2007 & IEC 60825-2:2004+A1+A2standards.

The 106426-00xx LC pigtail module connects to standard 38-pin QSFP+ connectors for hot plug capability. This allows the system designer to make configuration changes or maintenance by simply plugging in different LC pigtail modules without removing the power supply from the host system. The transmitter and receiver DATA interfaces are internally AC-coupled. LV-CMOS Transmitter Disable control input and Loss of Signal (LOS) output interfaces are also provided.

The LC pigtail module can be conveniently assembled into and released from the host system through the latch or pull-tab.

The LC pigtail module operates from a single +3.3V power supply over an operating case temperature range of 0°C to +70°C. The housing is made of metal for EMI immunity.
