    QSFP28 LR4 Optical Transceiver with 100GE for up to 10 km Reach , Cisco Huawei Compatible

    JUHUA's QSFP28-S31LLR4 100G QSFP28 LR4 optical transceiver is a full duplex, photonic-integrated optical transceiver that provides a high-speed link at aggregated data rate of either 103.125 Gbps or 111.81 Gbps over up to 10 km of SMF28. The module complies with IEEE 802.3-2015 Clause 88 and 83E standard and ITU-T G.959.1-2016-04.


    The transceiver integrates the receive and transmit path on one module. On the transmit side, four lanes of serial data are recovered by a programmable continuous time linear equalizer (CTLE), retimed and passed to four laser drivers, which control four lasers with center wavelengths of 1296 nm, 1300 nm, 1305 nm and 1309 nm. The optical signals are multiplexed to a single-mode fiber through an industry standard LC connector. On the receive side, four lanes of optical data streams are optically de-multiplexed by an integrated optical demultiplexer. Each data stream is recovered by a PIN photodetector transimpedance amplifier, retimed and passed to a CAUI-4 compliant output driver.


    This module features a hot-pluggable electrical interface, low power consumption and 2-wire I2C management interface.

    Electrical Input and Output Squelch Behavior:

    100G QSFP28 Optical Transceiver is compliant to the Rx squelch behavior described in SFF-8636 section 6.6.2.


    Rx(n)(p/n) are QS Lumentum QSFP28 transceiver. In the event of the optical signal on any channel becoming equal to or less than the level required to assert LOS, then the receiver data output for that channel shall be squelched or disabled. In the squelched or disabled state output impedance levels are maintained while the differential voltage swing shall be less than 50 mVpp.


    In normal operation the default case has Rx Squelch active. Rx Squelch can be deactivated using Rx Squelch Disable through the 2-wire serial interface. For the Lumentum 100G QSFP28 Optical Transceiver, squelch and output disable is controlled for each channel using bytes 240 and 241. Writing a '1' in the Squelch Disable register (byte 240) disables the squelch for the associated channel. Writing a '1' in the Output Disable register (byte 241) squelches the output of the associated channel. When a '1' is written in both registers for a channel, the associated output is disabled. The registers read all '0's upon power-up. All other squelch functionality details are outside the scope of this document.


    The 100G QSFP28 Optical Transceiver also support Tx Squelch Function.
