Cisco Meraki MA-QSFP-40G-SR-BD Compatible 40G BiDi QSFP+ for MS355/MS390/MS425

EdgeOptic's MA-QSFP-40G-SR-BD compatible is a Cisco Meraki-coded version of the EdgeOptic BIDI-40G-QSFP-150 multi-vendor 40G BiDi QSFP+ transceiver. Meraki's own product documentation describes the MA-QSFP-40G-SR-BD as a 40 GbE QSFP+ SR-BD fiber transceiver built for Meraki MS355, MS390, MS425 and MS450 switches, the cloud-managed MS-series platforms that this Meraki-branded ordering code targets. Meraki's product page names it a standard 40GBASE-SR-BD transceiver with a documented range of 150m. The module transmits 850nm and 900nm bidirectionally over a standard duplex LC fiber pair, one wavelength per direction per strand, instead of the four parallel 850nm lanes over an 8-fiber MPO/MTP that standard 40GBASE-SR4 uses. Meraki's own optics compatibility matrix documents reach as 30m on OM2, 100m on OM3 and 150m on OM4 multimode fiber for the Meraki-branded ordering code. EdgeOptic's BIDI-40G-QSFP-150 platform underlying this compatible is rated to 150m over OM3, OM4 or OM5 multimode fiber with a 2 dB average link budget, and the transceiver operates at a 41.25Gbps line rate to support 40G Ethernet (41.25Gbps, IEEE 802.3ba electrical and host interface), with additional supported protocol framing including OTU3 (43.01Gbps) and OTU3e2 (44.58Gbps) OTN and STM-256 (39.81Gbps) SDH and SONET.

The transceiver uses VCSEL transmitters and PIN photodiode receivers, with launch power of -4 to 5dBm per lane, receive sensitivity of -6 to 3dBm per lane, and a receiver overload of 3dBm. DDM and DOM diagnostics are supported for real time monitoring of transmit power, receive power, temperature and bias current. Operating temperature range is 0 to 70C, and the module draws standard +3.3V power. The module meets IEEE 802.3ba for the 40G Ethernet electrical and host interface, the QSFP+ MSA and SFF-8436 mechanical and electrical specifications, and carries CE and RoHS marks. The BiDi optical scheme itself follows the de facto industry MMF convention rather than a distinct IEEE optical PMD clause. This MA-QSFP-40G-SR-BD ordering code is part of Cisco Meraki's own accessory catalog for MS-series switches, distinct from the standard Cisco QSFP-40G-SR-BD catalog part, so verify the target switch model and MS-series firmware version against Meraki's own optics compatibility documentation before ordering. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, the MA-QSFP-40G-SR-BD ships next business day from EU stock with a lifetime warranty.
