H3C SFP-FE-LX-SM1550-BiDi Compatible 100M SFP Transceiver Module
Built for hosts recognizing SFP-FE-LX-SM1550-BiDi, this HT-manufactured SFP module delivers 100M transmission at 1550nm-TX/1310nm-RX. Its rated reach is 15km, with Simplex LC as the physical interface. The specifications and engineering guidance below support field technicians install, maintain and identify the exact compatible module, while keeping HT manufacture separate from the OEM cross-reference.

Field Installation and Maintenance
Inspect the connector and patch lead before installation, then support the fiber without pulling on the module housing. Release the latch properly during maintenance and keep dust protection on unused interfaces. If a module is removed for later use, retain its part-number label and record its original port. For this model, the principal parameters are data rate 155Mbps, wavelength 1550nm-TX/1310nm-RX, rated reach 15km.
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 100M interface configuration must match the remote equipment; sharing a SFP 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 15km design range before service.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -15~-8dBm; receiver sensitivity is < -30dBm. 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.
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.
H3C Compatibility and Factory Testing
Factory verification starts with the expected SFP-FE-LX-SM1550-BiDi 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.
Frequently Asked Questions
Is this an original H3C transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies SFP-FE-LX-SM1550-BiDi, not an original H3C-branded module.
Which fiber and connector are required?
Use Simplex LC with SMF. The specified maximum reach is 15km, 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.
Ordering Information
Quote HT part number SFP-FE-LX-SM1550-BiDi together with OEM reference SFP-FE-LX-SM1550-BiDi 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.
