The QSFP-DD MSA is a multi-company industry group. The QSFP-DD MSA has defined a high-density 8-channel (8x) module, cage, and connector system. QSFP-DD supports up to 400 Gb/s in aggregate over an 8 x 50 Gb/s electrical interface. QSFP-DD MSA recommended three duplex connectors, MDC connector, CS connector and SN connector. The following paragraph are […]
SFP-DD probably is the Next Generation SFP Module to Support 100G, It is based on 50G PAM4 signaling and will feature two channels, offering 100G in SFP-DD form-factor. By using this tiny SFP slot, it could realize the highest number of 100G front-panel pluggable ports in a Top-of-Rack switch. Eventually, two channels of 100G PAM4 […]

In the latest National Electrical Code 2020, there are Optical fiber cables with the following classification: OFNP, OFCP, OFNR, OFCR, OFNG, OFCG, OFN, and OFC. The following article briefly introduces these cable codes: OFNP: OFNP is short for Optical Fiber Nonconductive Plenum. The OFNP fiber cables are generally been installed in plenums duct and other […]
Most fiber optic transceivers we are using in the WDM transmission system are with fixed wavelength, neither a CWDM or DWDM wavelength. It will result in a huge back system in the case a certain transceiver is broken. while a tunable DWDM transceiver is an idea solution for it since it is able to adjust […]
Q: HOW IS QSFP-DD800 DIFFERENT THAN QSFP-DD? A: The QSFP-DD800 MSA is focused on the next generation of the QSFP family of modules. It will focus on increasing the aggregate module bandwidth and increasing individual line speeds to 112 Gb/s. In addition, changes are anticipated to the specification in the areas of thermal performance up […]

When purchasing a Cat5e, Cat6 or Cat6a Ethernet cable, different vender might offer UTP cable with different AWG (America Wire Gauge). What is AWG and which AWG should I choose? AWG = American Wire Gauge. This number is derived from the number of drawing dies that are needed to manufacture a certain cross-section. The larger […]
1. What is a QSFP-DD Optical Modules? A QSFP-DD Optical Transceiver with double density features, it refers doubling the number of high speed transmitter and receiver for the optical signal transmitting. The QSFP-DD transceivers is ready for the new PAM4 function for supporting 50Gbps per channel, which could support bandwidth over 400Gbps via MPO/MTP fiber […]
Currently, 400G QSFP-DD transceivers use 8 pairs of MMF to transmit signal in short distance, while bidirectional (BiDi) technology enables users to save the fibers for new data center deployment or maximize their usage of the existing fiber cabling infrastructure. the following article briefly explains the latest connector for QSFP-DD BIDI transceivers. 1. MPO Optical […]
