FS 100G QSFP28 Transceivers

As the demand for higher bandwidth and faster transmission speed keeps increasing, 100G Ethernet now accounts for a large proportion of the global market. More and more enterprise networks and data centers have shifted to 100G Ethernet data transmission. This article will explain in detail how different types of 100G QSFP28 transceivers boost 100G transmission.

How Does 100G QSFP28 Boost 100G Transmission?

100G QSFP28 SR4 for 100G Transmission

100G QSFP28 SR4 transceiver is designed for use in 100G Ethernet transmission of up to 100m over OM4 multi-mode fiber (MMF) using a wavelength of 850nm via a MTP/MPO-12 connector. It transmits or receives data through four independent channels, each channel supporting a data rate of 25Gbps of throughput. The maximum transmission distance is up to 70m over OM3 fiber and 100m over OM4 fiber.

100G QSFP28 SR4 transceiver uses the layer array at the transmitting end to convert the input parallel electrical signals into parallel optical signals which are converted to electrical signals through the PIN array at the receiving end.

100G CFP SR10 for 100G Transmission

100G CFP SR10 transceiver is also used for transmitting short-range 100G Ethernet data. It offers 10 transmit and 10 receive asynchronous channels operating at up to 11.2Gbps per channel. The maximum transmission distance is up to 100m over OM3 fiber and 150m over OM4 fiber.

The transmitter side of the module consists of an array of VCSELs (Vertical Cavity Surface Emitting Lasers) and associated circuitry, which converts 10 parallel electrical data inputs to 10 parallel optical data output signals and also converts 10 parallel optical signals into 10 parallel electrical signals through an array of PIN photodiodes and associated circuitry.

100G QSFP28 PSM4 for 100G Transmission

100G QSFP28 PSM4 transceiver is designed for use in 100G transmission over single-mode fiber (SMF) using a wavelength of 1310nm via a MTP/MPO-12 connector. Signals are also transmitted through four separate channels. The single-channel transmission rate is 25Gbps.

The electrical input signals are converted into parallel optical signals through the layer array. The parallel optical signal is converted to a parallel electrical signal but it is used for single-mode fiber, not multi-mode fiber as in the case of 100G QSFP28 SR4.

100G QSFP28 CWDM4 for 100G Transmission

100G QSFP28 CWDM4 transceiver provides aggregated 100G data rate over 2 km on SMF. A 100G QSFP28 CWDM4 transceiver converts input electrical data to CWDM optical signals, and there are four independent channels of 25Gbps multiplex to a single 100Gbps channel.

There are four main wavelengths involved, 1271nm, 1291nm, 1311nm, and 1331nm. The four optical signals from the four wavelengths are multiplexed and coupled to SMF through an industry-standard LC connector. On the receiving side, the demultiplexer splits the four wavelengths apart.

100G QSFP28 LR4 for 100G Transmission

100G QSFP28 LR4 transceiver is mainly applied in 100G Ethernet long-haul transmission and the maximum transmission distance is up to 10km. The transceiver converts the optical input signal into LAN WDM optical signal with four channels separately at the receiving end, and then it will convert the optical signal into four electrical channel signal output channels.

The 100G QSFP28 ER4 is usually connected to the single-mode fiber through an industry-standard LC connector. It can multiplex four wavelengths (1295nm, 1300nm, 1305nm, 1310nm) of optical signals that can be aggregated onto an SMF fiber to achieve 100G transmission.

100G QSFP28 ER4 for 100G Transmission

100G QSFP28 ER4 transceiver is designed for use in 100GBASE Ethernet throughput up to 40km over single mode fiber (SMF) using a wavelength of 1310nm via duplex LC connectors.

100G QSFP28 ER4 transceiver can multiplex four wavelengths (1295nm, 1300nm, 1305nm, 1310nm) of optical signals. The four optical signals from the four wavelengths are multiplexed and coupled to SMF through an industry-standard LC connector to realize 100G transmission On the receiving end, the demultiplexer splits the four wavelengths apart.
