What do the suffixes “SR8, DR4, xDR4 FR4 and 2FR4” stand for OSFP Modules?

The letters are reach specifications, and the number refers to the number of optical channels: Description Connector Type SR8: “SR” refers to 100m reach using multi-mode fiber, and “8” implies there are 8 optical channels. Each of the 8 optical channels from an SR8 module are carried on separate fibers, resulting in a total of […]

400G OSFP Transceivers and Its Fiber Type and Connector Type

The OSFP stands for an “Octal Small Form-factor Pluggable”. It is described as an “Octal” module because the electrical interface of an OSFP connector consists of 8 electrical lanes, running at 50Gb/s each, for a total of bandwidth of 400Gb/s. OSFP SR8, 8x50G Optical transceiver module is designed for use in 400 Gigabit links over […]

400G QSFP-DD Transceivers and Its Fiber Type and Connector Type

The QSFP-DD stands for a “Quad Small Form-factor Pluggable (QSFP) – Double Density (DD)”. The QSFP-DD connector also has 8 electrical lanes. The QSFP-DD form factor is similar to the QSFP form factor, except a second row of electrical contacts has been added to the QSFP connector in order to increase the number of high […]

What is Structured Cabling

Structured cabling is a telecommunications cabling infrastructure that consists of a number of standardized smaller elements called subsystems for the enterprise, banks, and campus etc. These subsystems are the Work Area, Horizontal Cabling, Telecommunications Room, Backbone Cabling (Riser), Equipment Room, and Entrance Facility. The structured cabling can have a cabling infrastructure based on optical fiber, […]

Ist OM5 die Marktwahl für das Rechenzentrum?

Was ist OM5? OM5 geht einen Schritt weiter. Wie man aus der Tabelle ersehen kann, unterscheiden sich die Eckdaten bei 850nm nicht von OM4, jedoch ist das Übertragungsfenster vergrößert worden, so dass ein nutzbarer Wellenlängenbereich von 850 bis 953nm zur Verfügung steht (WBMMF = Wide Band Multimode Fiber). Mit den heute üblichen VCSEL Lasern als […]

How will SWDM and OM5 affecting your data center upgrade?

Currently, most of the data center are using OM3 and OM4 Multimode fiber to deploying 10G Ethernet. When we are updating from 40G and 100G, mostly we are using cost-effective QSFP-SR4 and QSFP28-SR4 Multimode transceivers with a multi-fiber interface. In the cabling infrastructure of the data center, abundant of duplex fiber and multi-fiber patch cord, […]

5 Reasons to buy 100G QSFP28 Transceivers

1. What makes 100G QSFP28 Transceiver different from 40G QSFP+ Transceiver? It has the same size form factor and the maximum number of ports as a QSFP+ transceiver, but the lane speeds are increased from 10Gbps to 25Gbps. The increase in panel density is even more dramatic when compared to some of the other 100 […]
