Is this compatible with MMA1T00-VS?
Yes. This is a third-party module built to the same IEEE 802.3cd 200GBASE-SR4 / InfiniBand HDR specification and EEPROM-coded so the host reads it as a supported optic. It is offered as a functional equivalent to MMA1T00-VS — it is an FOT module, not an OEM-branded part. Tell us the exact switch model and software version on your RFQ and we code and traffic-test against that platform before shipping.
What reach will I actually get on OM3 / OM4 multimode?
This module is specified to 100 m OM4. Real-world reach depends on your channel loss budget — every mated connector pair costs roughly 0.3 dB and every splice about 0.1 dB. Measure the installed channel rather than assuming the map distance, and keep 2–3 dB of margin for ageing and future repairs.
Which MPO polarity and polish do I need?
Single-mode parallel interfaces are APC (angled, green) and multimode are normally UPC. Polarity follows your cabling system convention — Type B is the usual choice for a straight port-to-port link. Our MPO polarity guide covers the whole scheme, and we can build trunks and harnesses to match.
Does breakout need to be configured on the switch?
Yes. The optic and the cable are passive to that decision — the lane grouping is set in the switch OS, and on most platforms a port cannot be re-aggregated without a reload. Decide the breakout ratio before you cable, not after.
Can you code these for my switch vendor?
Yes. We program the EEPROM at manufacture for NVIDIA/Mellanox, Cisco, Arista, Juniper, Huawei, HPE, Dell, Extreme and generic MSA. Specify the platform on your RFQ; mixed coding (a different vendor at each end) is routine for inter-vendor links.
Do you supply test reports and samples?
Free samples are available so you can qualify the module in your own environment before committing to volume. Per-order test reports are supplied on request, and sample reports can be provided for tender documentation.
