About this model
The ER EML 40KM model serves long 100G links, where forward error correction helps the signal travel further without errors, and where a 40km reach suits links between buildings, campuses, or data centre sites. A buyer who needs a long 100G link should confirm the reach, the fiber type, and the connector for their exact equipment, because a module that mismatches on any of those will not serve, however far its title reach extends.
The description below is transcribed from the official product page for this model. Where the official page states a full specification table, that table is reproduced; where it states only a title, the title wording is transcribed and labelled as title wording, and no specification table is built from it, because a model name does not evidence a specification.
Official title, as stated
Official title, as stated: QSFP28 100G ER EML Fiber Optical Transceiver Module With FEC Up To 40KM.
That wording is the official title for this model, transcribed exactly. It is not a specification table: the title names the model and its headline features, but a title does not evidence the full specification, and this site does not convert title words into table rows. A buyer who needs the full specification for this model should ask for it in the inquiry, naming the exact model.
Compatibility, as listed by the company
The company profile states compatibility with Huawei, Cisco, HP, H3C, Juniper and MikroTik.
That statement is the company profile's own compatibility statement, quoted with attribution. It is not a statement by any of the named equipment makers, it does not imply authorisation, certification, or partnership with them, and it does not make any named maker's product a product of this company. A buyer should confirm compatibility for their exact equipment in the inquiry, before ordering, because listings change and equipment variants differ.
Trade terms for this model
No trade figures are stated for this model page, because no per-page trade block is evidenced for this model in the material used here. Minimum order, lead time, payment, shipping and warranty terms for this model are confirmed in the inquiry, naming the exact model, rather than assumed from another model's page.
Trade terms are stated per model only. A term stated here applies to this model page, not to the family and not to the site. Where this page states no trade figures, that is because no per-page trade block is evidenced for this model in the material used here, and the terms are confirmed in the inquiry rather than assumed from another model's page.
What this page does not state
This page states no price, because no current price is evidenced. It states no payment, shipping or warranty specifics beyond the per-model trade terms above, because none are evidenced for this model; those are confirmed in the inquiry, in writing, before payment. It states no certificate name, number or issuer, because none are evidenced as current; certificates are available upon request.
This page also states no characteristic the official page does not state. Where a characteristic matters to your use and is not given above, ask for it in the inquiry, naming this model, so the answer is specific rather than general.
What to confirm before ordering
Name this model, the equipment it must serve, the quantity you have in mind, and the market you sell into. Ask for the specification for the exact model, the minimum order quantity, the lead time with its meaning, the warranty terms, the payment and shipping terms, and the certificates that apply to your market, by name, with documents attached. All quantity, lead-time and warranty figures are confirmed in the inquiry, in writing, before payment, except for the per-model trade terms stated above where they exist.
Before payment, confirm the minimum order quantity, lead time, payment, shipping and warranty terms for your order. Certificates are available upon request.
