Which hardware platforms is this module compatible with?

It is compatible with all SONET/SDH line cards and routers supporting industry-standard SFP/SFP+ cages for OC-12/STM-4.

Can I mix this module with multimode transceivers?

No. Mixing single-mode and multimode transceivers on the same link will result in signal loss and link failure.

What is the operating temperature range?

The ESR-1OC12/P-SMI operates reliably between 0 °C and 70 °C (standard commercial range).

How much power does the module consume?

Typical power consumption is 1.2 W, ensuring minimal impact on chassis power budgets.

How do I install the ESR-1OC12/P-SMI?

Simply slide the module into an empty SFP/SFP+ slot until it clicks, then attach the LC duplex fiber cable.

How can I verify the module is functioning correctly?

Check the host device’s interface status LEDs and use show interface commands to confirm link up, proper rate, and error-free traffic.

What is the difference between OC-12/STS-12c and STM-4?

OC-12/STS-12c is the SONET term for 622 Mbps, while STM-4 is the SDH equivalent at 622 Mbps. This module supports both.

Is the ESR-1OC12/P-SMI RoHS compliant?

Yes. The module meets all RoHS 2.0 directives for hazardous substance reduction.

What warranty covers the ESR-1OC12/P-SMI?

It includes a limited lifetime warranty covering manufacturing defects and premature failure under normal operation.

Where can I purchase or order this module?

You can order through authorized distributors, our online store, or by contacting our sales team directly.

What are common use cases for this transceiver?

Typical applications include metro MAN links, backbone WAN aggregation, and POS interconnects in carriers and ISPs.

What is the typical lead time for delivery?

Standard lead time is 2–5 business days for in-stock modules; custom orders may require up to 10 business days.
