Eoptolink 400G QSFP-DD and OSFP Transceivers fully support CMIS4.0

Dublin, Ireland, September 23, 2019 – Eoptolink Technology Inc., Ltd (SZSE: 300502) today announced the full support of CMIS 4.0 for its 400G QSFP-DD and OSFP optical transceivers.

CMIS 4.0 enables customers to upgrade MCU and DSP firmware from the host system, offer additional digital diagnostics and has an improved state machine.
Diagnostic functions include
• PRBS Generation and Checking
• Loopback functions
• SNR data
• PAM4 Level Transition Parameters
• Pre-FEC BER and Uncorrected Error Count data

“We are pleased that our complete OSFP and QSFP-DD transceiver portfolio can now be ordered with either CMIS 3.0 or CMIS 4.0 support”, says Sean Davies, Director of Sales in Americas.

 

Eoptolink has a strong portfolio of industrial temperature SFP+, SFP28 and QSFP28 transceivers supporting 10G/25G Ethernet and CPRI protocols.

Eoptolink has a strong portfolio of industrial temperature SFP+, SFP28 and QSFP28 transceivers supporting 10G/25G Ethernet and CPRI protocols. Our i-temp transceivers operate from -40⁰C to +85⁰C and do not need a warm up period to achieve a higher operating temperature.

The QSFP-DD form-factor doubles the number of data-lines between the host equipment and the transceiver.

Eoptolink’s 2x100G transceivers take advantage of this new building practice and offer two 100G interfaces in one QSFP-DD transceiver. The 100G interfaces are fully compatible to CWDM4, 4WDM-10 or LR4 standards.
These transceivers offer a way of either increasing the port density in 100G switches or to connect in 400G switches more effectively to legacy equipment.

Difference between 100G ER4, 100G ER4 Lite and 4WDM-40

Below you will find a summary of the differences for 100G ER4 transceiver types. There are 3 different MSAs, or standards, targeting transmission distances of up to 40 km:

  • 100G ER4
  • 100G ER4 Lite
  • 4WDM-40

Eoptolink Samples the Lowest Power 400G DR4/FR4 Transceivers for Hyper-scale Data Center and Cloud Networks

CHENGDU, China, January 29, 2019 – Eoptolink Technology Inc., Ltd (SZSE: 300502) today announced the immediate availability of the world’s first sub-10W 400G QSFP-DD and OSFP DR4 and FR4 optical transceiver products. The new transceiver modules offer best-in-class performance while delivering unprecedented power efficiency enabling high volume deployment of 400GbE links in hyper-scale datacenter and cloud networks.
