What does PSM4 stand for?

Parallel Single Mode 4-channel (PSM4) is a type of single-mode transceiver that uses a parallel fiber design for reaches up to 2 km. For reaches up to 100-meter Short Reach 4-channel (SR4) multi-mode transceivers are used.

How do Qsfps work?

The QSFP 100G PSM4 converts parallel electrical input signals into parallel optical signals by the Layser Array and then transmitted in parallel on the MTP/MPO single mode ribbon fiber. Upon reaching the receiving termination, the PIN array converts the parallel optical signals into parallel electrical signals.

What is QSFP used for?

The Quad Small Form-factor Pluggable (QSFP) is a compact, hot-pluggable transceiver used for data communications applications. The form factor and electrical interface are specified by a multi-source agreement (MSA) under the auspices of the Small Form Factor Committee.

What is QSFP28 LR4?

The QSFP28 LR4 is a hot-pluggable, four-channel, and full-duplex optical transceiver module designed for long-distance transmission up to 10km in the 100G Ethernet network with a working bandwidth of 1295nm to 1310nm. Simultaneously, the QSFP 100G LR4 modules are fully compliant with IEEE 802.3ba standard.

What is SFP transceiver used for?

SFP, an acronym of small form-factor pluggable, is a compact and hot-pluggable transceiver used for both telecommunication and data communication applications. It connects motherboards of network devices (such as switches and routers) with optical or copper cables.

What is 100G PSM4?

Welcome To The 100G PSM4 MSA PSM4 is a multi-vendor, multi-technology optical interface standard for 100Gbps optical interconnects. It allows for support by multiple electrical form factors, including QSFP, CFP, and embedded optical engines.

Is QSFP an Ethernet?

QSFP connectors are still small and hot-pluggable, and they still support Ethernet and fiber optics.

What is the fastest SFP?

SFP data transfer rates can range between 10 Mbps to 1000 Mbps (1 Gbps). For a more powerful data transmission and faster gigabit ethernet, SFP+ transceivers can provide up to 10 Gbps rates and for optimal speeds, QSFP/QSFP+ can reach up to 40 Gbps.

What is 100GBASE LR4?

◆ 100GBASE-LR4 is duplex, two-fiber data link for 10km (Long Reach) ◆ 25Gb/lane (wavelength) X 4 wavelengths = 100Gb/s.

What is an LR4 connector?

The LR4 standard is used for medium range fiber connections over 9/125um single-mode fiber. The optical connectors are LC on the QSFP-10010-LR4. The widespread LC connector provides easy connectivity with common fiber cabling, making the transceiver a convenient choice.

What is an SFP in networking?

An SFP port is a slot on a network device or computer into which small form-factor pluggable (SFP) transceivers are inserted. An SFP transceiver, also known as an SFP module, is just a hot-swappable, pinky-sized metal component that, when connected to another device using a cable, allows for the transmission of data.

What is a Cisco SFP?

Small form-factor pluggable (SFP) is a compact optical transceiver. Cisco Transceiver Modules support Ethernet, Sonet/SDH and Fibre Channel applications across all Cisco switching and routing platforms.

What is the 100G psm4 optical interface specification?

The 100G PSM4 Specification is targeted to service that need on a parallel single mode infrastructure, as a critical need of next generation data centers. This specification defines a four lane (per direction) 100 Gb/s optical interface to single mode fiber (SMF) media.

What is the form factor of the 100G psm4 module?

As shown in Figure 1, the 100G PSM4 Transceiver Module (100G PSM4 Module) provides Transmit Optics and Receive Optics between the Host IC and the fiber optic media. A particular form factor, e.g. QSFP28 or CFP4, is not defined and the 100G PSM4 Transceiver Module may be implemented in various form factors.

Can a psm4 be used as a 100g transceiver?

On one hand, it can be used for 100G to 100G direct connection. On the other hand, the QSFP28 PSM4 also can be applied for achieving 25G to 100G migration in short distance.

What are the compliance points on a 100g psm4?

A 100G PSM4 Transmit/Receive block diagram is shown in Figure 2. The electrical and optical interface compliance points are identified as TP1 for the electrical input signals, TP2 for the optical output signal, TP3 for the optical input signal and TP4 for the electrical output signal.
