FAQs About ADOP QSFP28 Optical Modules

Q: What compatible brands of QSFP28 modules are available in ADOP.CN?

A: ADOP offers a high-quality QSFP28 module that is compatible with mainstream brands including Cisco, HP, Juniper, Brocade, Dell, Extreme, H3C, Arista, Huawei, Intel, IBM, Netgear, Ciena, D-Link, Avago, F5 Networks, Avaya, Alcatel-Lucent, Aruba Networks, Allied Telesis, SMC Networks, TRENDnet, etc.

Q: What kinds of custom choices are offered in ADOP.CN?

A: ADOP provides custom options such as compatibility (with different brands), transmission distance, operating temperature, label pattern, label colors and etc. And we appreciate any inquiry for customized products and solutions for your specific preference and requirements.

Q: Can ADOP.CN QSFP28s and patch cables be shipped directly from the USA or Europe?

A: Yes. ADOP has built warehouses in US and Germany. And we’ve prepared adequate stock of optical transceiver modules and patch cables in both the locations. Generally, customers can enjoy same-day shipping given that all the ordered items are ready in stock.

Q: What makes QSFP28 different from QSFP+?

A: QSFP28 has the same size form factor and the maximum number of ports as a QSFP+ transceiver, but the lane speeds of QSFP28 are increased from 10 Gbps to 25 Gbps. It’s made specifically for large-scale data centers and carriers to scale to 100G Ethernet.

Q: Can QSFP28 interoperate with 100GBASE-SR10?

A: No. The QSFP28 has just 4 electrical lanes, which is not enough to support 10 lanes of 10G electrical interface. A QSFP28 can only support a 4x25G electrical interface but not 10x 10GbE. As a result, the QSFP28 cannot interoperate with SR10 based 100GbE transceivers.

Q: Which 100G QSFP28 transceiver can be used in breakout mode?

A: Breakout mode refers to running multiple ports at lower speeds. Currently, there are three types of QSFP28 modules supporting 4x25G breakout mode: QSFP-100G-SR4, QSFP-100G-PSM4, and QSFP-100G-CR4.
