Syrotech-GOXQ28-100GBASE-ER4-transceiver module-QSFP28-MSA-LAN WDM-hot pluggable-40Km

QSFP28 100GBASE-ER4 is Syrotech's 100Gb/s optical communication module compliant with Ethernet 100GBASE-ER4 Lite standard. Input channels of 25Gb/s electrical data are converted into LAN WDM optical signals and multiplexed into a single channel for 100Gb/s transmission. 

On the receiver side, the module converts 4 LAN WDM optical signals into 4 electrical output channels from a 100Gb/s optical input. As defined in IEEE 802.3ba, the wavelengths of the four LAN WDM channels are 1295.56, 1300.05, 1304.58, and 1309.14 nm.APD receivers with high sensitivity provide superior performance for 100Gigabit Ethernet applications up to 30km with no FEC and 40km with FEC.

PRODUCT SPECS:

In the transceiver module, four channels of 25Gb/s electrical data are received, which are reshaped and reduced in jitter by a four-channel Clock and Data Recovery (CDR) IC. Each of the 4 cooled EML lasers in the Transmitter Optical Sub-Assembly (TOSA) is then driven by an EML laser driver IC that converts the 4 electrical channels into an optical signal. IEEE 802.3ba 100GBASE-ER4 specifies a specific wavelength for each laser when it launches an optical signal. 

The optical output power of each channel is maintained constant by an automatic power control (APC) circuit. A 4-to-1 optical WDM MUX will split these four optical signals into one fiber. By using the TX_DIS hardware signal or the 2-wire serial interface, the transmitter output can be turned off.

ELECTRICAL SPECS:

Four-lane LAN WDM optical signals are received by the receiver. By demultiplexing the optical signals through a 1-to-4 optical DEMUX, each channel of optical signals is fed into one of four receivers packaged into the Receiver Optical Sub-Assembly (ROSA). Electrical signals are converted from optical signals by receivers.

As the regenerated electrical signals are de-jittered and retimed, the RX portion of the 4-channel CDR amplifies them. Four-lane output electrical signals are retimed to meet CEI-28G-VSR interface requirements. A DOM section also monitors each optical signal that is received. Through the 2-wire serial interface, the monitored value is reported. In the event of weak optical signals, the RX_LOS hardware alarm will be triggered.
