Arista Networks QSFP-ER-100G Compatible 100G QSFP28 ER Transceiver Module

Arista Networks QSFP-ER-100G Compatible 100G QSFP28 ER Transceiver Module

This Arista Networks QSFP-ER-100G compatible transceiver provides 100G connectivity in a hot-swappable QSFP28 package. Its optical design operates at 1310nm[Lane Center Wavelengths RangeTX 1308.09-1310.19 RX 1304.5-1317.5] for up to 40km, using Duplex LC. Complete parameters and related OEM references help structured fiber installations preserve a documented and serviceable optical channel.

Applications and Optical Link Design

This BiDi interface is useful where only one fiber strand is available between two sites or racks. It must be paired with the complementary wavelength direction: one end transmits on the wavelength that the other end receives. Verify the paired part number, connector polish and fiber plant before installation, and measure link loss against the specified optical budget.

Before deployment, check the host port type, supported data rate and firmware requirements. The 100G interface configuration must match the remote equipment; sharing a QSFP28 housing alone does not make two transceiver types interoperable.

This single-fiber interface must be paired with the complementary wavelength direction. One end transmits on the wavelength the other receives. Verify connector polish and measure loss over the 40km design range before service.

Arista Networks Compatibility and Factory Testing

Factory verification starts with the expected QSFP-ER-100G identity and finishes with an operating host link. EEPROM data, diagnostic visibility and the stated optical parameters are assessed together. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is 1.7~7.1 dBm; the stated optical power budget is 17.7dB. A sound acceptance record includes link state, diagnostic temperature, supply voltage and transmit or receive levels where the host exposes them. Compare the readings with the stated ranges rather than treating any received light as proof of adequate margin. Persistent alarms or borderline values should trigger an end-face and complete-channel inspection. Diagnostic monitoring is listed as Supported. Before every insertion, keep dust caps in place until the patch lead is ready, avoid touching the optical end face and use an appropriate inspection and cleaning procedure. Do not look into an active optical interface.

Structured Fiber Pathways and Serviceability

Treat the transceiver as part of the complete channel. Follow the intended patch-panel route, maintain bend control and leave service access around the port. Confirm connector polish and fiber type at every mated pair; a documented service allowance is preferable to excess slack concealed inside a rack. For this model, the principal parameters are data rate 100 Gbps, wavelength 1310nm[Lane Center Wavelengths RangeTX 1308.09-1310.19 RX 1304.5-1317.5], rated reach 40km.

Ordering Information

Quote HT part number QSFP-ER-100G together with OEM reference QSFP-ER-100G and quantity. Add the host model and software release when pre-order verification is required. Neutral labels, customer packaging and project-specific compatibility review are available on request.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.

Quality Assurance and Packaging

Quality control covers the optical or electrical interface, host identification and operating link. The verified unit is then individually protected and cartoned. Customer references, rack groups and project packing lists can be added for volume orders.

Frequently Asked Questions

Is this an original Arista Networks transceiver?

No. It is an HT-manufactured compatible alternative for equipment that specifies QSFP-ER-100G, not an original Arista Networks-branded module.

Which fiber and connector are required?

Use Duplex LC with SMF. The specified maximum reach is 40km, subject to fiber quality and total link loss.

Can it be mixed with another wavelength or reach version?

Only when the two ends share the same optical standard, wavelength plan and supported data rate. Check the exact part numbers and link budget rather than relying only on the module form factor.
