Project Documentation and Traceability
Large deployments are easier to audit when the order code, optical standard and endpoint record agree. Keep the OEM reference in the compatibility document and the HT part number on the packing list. Labels and carton groups can be arranged by rack or port plan so installers need not identify modules by appearance. For this model, the principal parameters are data rate 1.25Gbps, wavelength 850nm, rated reach 550m on 50 / 125µm OM2 MMF275m on 62.5 / 125µm OM1 MMF220m on 62.5 / 125µm FDDI MMF.
Brocade Compatibility and Factory Testing
Compatibility testing for E1MG-SX-OM combines identification with a live link and available transmit, receive and alarm information. Connector condition is inspected separately. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
Applications and Optical Link Design
Typical deployments include switch-to-switch, switch-to-server and aggregation links inside a data hall or between adjacent equipment rooms. The Duplex LC interface connects to the specified multimode cabling, and the stated reach depends on fiber grade and link loss. Keep this interface on the matching multimode optical standard rather than connecting it directly to a single-mode wavelength or reach variant.
Before deployment, check the host port type, supported data rate and firmware requirements. The 1G interface configuration must match the remote equipment; sharing a SFP housing alone does not make two transceiver types interoperable.
The multimode channel should use the fiber grade associated with the stated 550m on 50 / 125µm OM2 MMF275m on 62.5 / 125µm OM1 MMF220m on 62.5 / 125µm FDDI MMF reach. Keep the Duplex LC end faces clean and avoid tight bends. Different multimode standards are not interchangeable merely because they share a connector.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -9.5~-3dBm; receiver sensitivity is < -17dBm. During commissioning, record the host diagnostic readings after the link has stabilized and compare them with those limits. DOM values are useful operational indicators, but they do not replace calibrated optical measurements when a link is marginal. Investigate unexpected loss through connector inspection, cleaning and a channel measurement before replacing the module. 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.
Frequently Asked Questions
Is this an original Brocade transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies E1MG-SX-OM, not an original Brocade-branded module.
Which fiber and connector are required?
Use Duplex LC with MMF. The specified maximum reach is 550m on 50 / 125µm OM2 MMF275m on 62.5 / 125µm OM1 MMF220m on 62.5 / 125µm FDDI MMF, 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 E1MG-SX-OM together with OEM reference E1MG-SX-OM 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
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.
