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 10G interface configuration must match the remote equipment; sharing a SFP+ housing alone does not make two transceiver types interoperable.
BiDi operation saves a fiber strand but makes wavelength orientation critical. Record the part installed at each end and check its paired receive wavelength. The 20km rating still depends on total channel loss, including connectors and splices.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -6~3dBm; receiver sensitivity is < -14.4dBm; the stated optical power budget is 8.4dB. Digital diagnostics make later maintenance easier when baseline values are captured at installation. Save the initial readings with the port and OEM reference, then investigate meaningful changes rather than reacting to a single transient value. Diagnostic support depends on the host as well as the module, so unavailable fields should be confirmed with the platform documentation. 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.
Procurement and Asset Identification
A useful purchase order identifies the host platform, expected OEM code and optical standard separately. This prevents a module with the same housing but another wavelength, reach or identification profile from being substituted. For mixed deployments, keep one order line per OEM reference and reconcile each received unit with its intended port. For this model, the principal parameters are data rate 10.3125Gbps, wavelength 1270nm-TX/1330nm-RX, rated reach 20km.
Arista Networks Compatibility and Factory Testing
Factory verification starts with the expected SFP-10G23-BX20 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.
Ordering Information
Use SFP-10G23-BX20 as the compatibility cross-reference and SFP-10G23-BX20 as the HT ordering identity. Keep other reaches or wavelength directions on separate order lines. Neutral labels, customer packaging and project-specific compatibility review are available on request.
Quality Assurance and Packaging
Before packing, the module receives interface inspection, identification and link checks. Protective packaging avoids pressure on the connector and latch. 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 SFP-10G23-BX20, not an original Arista Networks-branded module.
Which fiber and connector are required?
Use Simplex LC with SMF. The specified maximum reach is 20km, 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.
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.
