The ESR1OC48/P/SRPSML is a hot-pluggable OC-48/STM-16 optical transceiver module designed for POS and SRP applications over single-mode fiber in long-reach networks.
The module supports a fixed data rate of 2.488 Gbps for OC-48/STM-16 Packet over SONET (POS) and Synchronous Residual Packet (SRP) transport.
Over standard single-mode fiber, the SM-LR transceiver reliably reaches up to 80 kilometers for OC-48/STM-16 transmission.
This OC-48/STM-16 POS/SRP SM-LR module uses an SC/APC duplex connector for low-reflection, single-mode optical links.
The module transmits at a central wavelength of 1310 nm, optimized for long-range single-mode fiber performance.
Yes. The ESR1OC48/P/SRPSML supports hot-swapping, allowing insertion or removal without powering down the host system.
Yes. It includes SFF-8472 compliant DDM functions for real-time monitoring of optical power, temperature, and voltage.
The transceiver is compliant with ITU-T G.957, IEEE 802.3, and ANSI T1.105, supporting POS and SRP framing over SONET/SDH.
The module offers a minimum receiver sensitivity of –34 dBm and a transmitter output up to +0 dBm, delivering a 34 dB optical budget.
It operates reliably from 0°C to 70°C (32°F to 158°F) to meet extended industrial temperature requirements.
It is compatible with standard XFP and XENPAK cages on routers, switches, and SONET/SDH transport equipment.
Align the module with the host port, slide it in until the latch clicks, then secure it using the integrated ejector tab.
Use the host’s DDM management interface or an optical power meter to check real-time diagnostics and link integrity.
The module is CE, FCC, and RoHS compliant, ensuring safety, electromagnetic compatibility, and environmental compliance.
It includes a two-year warranty covering defects in materials and workmanship, backed by responsive technical support.
