Questions & Answers
What is the ESR-1OC12/P-SMI module?
The ESR-1OC12/P-SMI is a single-mode, intermediate-reach transceiver supporting OC-12/STS-12c and STM-4 POS applications over fiber.
Which protocols does the ESR-1OC12/P-SMI support?
It supports SONET OC-12/STS-12c and SDH STM-4 packet-over-SONET (POS) data transport protocols.
What is the maximum transmission distance?
The module achieves intermediate reach up to 15 km over single-mode fiber, depending on link budget and fiber quality.
What fiber type and connector are required?
ESR-1OC12/P-SMI uses single-mode fiber with LC duplex connectors for both transmit and receive channels.
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?
