100G QSFP28 (Quad Small Form-Factor Pluggable 28) optical transceivers are widely used by Internet Service Providers, Mobile Operators and Data Centers globally as QSFP28 has become dominant form factor of 100G. EDGE Optic’s compatible QSFP28 portfolio consists of transceivers which can operate over Single Mode or Multi Mode optical fiber, can be used for connections from couple of meters up to 80 kilometers and are suitable for 100G Ethernet, Optical Transport Network OTU4 and 128G Generation 6 Fiber Channel applications. Our QSFP28 portfolio is fully compliant to industry standards (QSFP28 MSA) and can work in 80% of networking equipment, where is not implemented special algorithm for protection against third party modules. However – we have accumulated deep expertise in custom-encoded firmware for our 100G QSFP28 portfolio in order to make it work in almost any brand equipment.
100G Ethernet QSFP28 Transceivers:
100G Ethernet QSFP28 Transceivers are designed for 100G Ethernet application using fixed 103.25 Gbps data rate, comprehending 100G SR4, LR4, ER4 Lite, ZR4 which are defined by IEEE 802.3ba/802.3bm, 2km PSM4 which is defined by 100G PSM4 MSA and CWDM4/CLR4 modules which are defined by 100G CWDM4 MSA and 100G CLR4 Alliance. Additionally here are 2 special modules: 100G QSFP28 SR4 Low Power module which is useful in modern data center environments and can help to save power and lower heat dissipation and there is 100G QSFP28 LR4 Long Haul (20km) module which is extended reach version of 100G LR4.
Short Range 100G Ethernet QSFP28:
Extended Range and 80km (ZR) 100G Ethernet QSFP28:
OTU4/128G Fiber Channel QSFP28 Transceivers:
OTU4/128G Fiber Channel module chipset supports multi rate speeds: 103.125-112.2 Gbps and such applications as 100G Ethernet (103.125Gbps), Optical Transport Network OTU4 4l1-9D1F (112 Gbps) and 128G Generation 6 Fiber Channel (112.2 Gbps).
Single Lambda QSFP28 Transceivers:
Single Lambda QSFP28 Transceivers transport 100G Ethernet (103.125Gbps) per optical channel using PAM4 modulation over pair of single-mode optical fiber. Ability to transport 100G Ethernet over single lane, comparing to current mainstream 100G modules which transport 25G per lane and use 4 lasers is great breakthrough in optical industry and paves the way for future 100G and 400G connections. Our portfolio consists of 100G-DR which is defined by IEEE802.3cd and 100G-FR and 100G-LR which are defined by 100G Lambda MSA.
Industrial Temperature QSFP28 Transceivers:
For optical module use under harsh environments, we recommend 100G QSFP28 SR4 and LR4 Industrial Temperature versions which support -40 to 85 Celsius operating temperature range.
RX Only QSFP28 Transceivers:
As global online data traffic is asymmetrical – especially this statement is valid nowadays when biggest share of global traffic is video streaming, there is much more downlink traffic then uplink. To address this challenge and help engineers design network connections according to real life traffic requirements Rx Only QSFP28 100G Transceivers come in play. As Rx Only modules don’t have TOSA laser, just PIN receivers they are cost efficient alternative comparing to standard 100G Ethernet QSFP28 modules which have both TOSA laser and PIN receiver.
