◆ Description:

Miray’s 622M-LX160-SM is a high-performance small form factor pluggable (SFP) transceiver module for duplex optical data communications such as SDH STM-4/SONET OC-12 and 622Mb/s ATM ultra long reach the application. This SFP transceiver module provides 150~160km transmission distance over single mode fiber at a nominal wavelength of 1550nm. The transmitter section uses a 1550nm DFB laser that is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses a high-speed APD photodiode (PD) and trans-impedance preamplifier. The 622Mbps SFP module series is fully compliant with SFP Multi-Sourcing Agreement (MSA) and SFF-8472.

Long-Reach Optical Link Performance for Carrier and Industrial Networks
Miray’s 622M SDH STM-4/SONET OC-12 SFP module is built for buyers who need a practical, high-reliability transceiver for long-distance fiber links in an ethernet switch, network switch, or transport platform. Designed for 622Mb/s applications, it supports SDH STM-4, SONET OC-12, and ATM deployments while delivering a stable optical connection over singlemode fiber at 1550nm. The module’s hot-pluggable SFP form factor and LC duplex interface make it a strong fit for system builders, optical transceiver manufacturers, and procurement teams looking for a compact sfp module that supports dependable operation in structured network environments, including installations associated with industrial ethernet switch manufacturers and top network switch manufacturers.

Proven Optical Design with Monitoring and Installation Flexibility
This transceiver combines a 1550nm DFB laser transmitter with a high-speed receiver section using APD photodiode technology and trans-impedance amplification, helping maintain consistent signal performance across long-distance singlemode links. It is fully compliant with SFP MSA and SFF-8472, includes a monitoring interface, operates from a single +3.3V power supply, and supports hot-pluggable installation for easier maintenance planning. With a transmission range of 150~160km on 9/125 μm SMF and a maximum power rating of 1W, this transceiver is well-suited to operators who need dependable optics for mission-critical cabinet, rack, and field deployments. The RoHS-compliant, lead-free build also aligns with procurement standards for regulated projects and long lifecycle supply programs.

Application Fit for Long-Distance Transport and Network Expansion
For network operators, contractors, and resellers supporting telecom, transport, utility, or campus backbones, this SFP module offers a practical way to extend links where standard short-reach optics are not enough. Its industrial, extended, and commercial temperature versions provide deployment flexibility from -40°C to 85°C, -5°C to 85°C, or 0°C to 70°C depending on site requirements, making it suitable for controlled indoor systems as well as harsher environments. Whether used inside a poe switch aggregation layer, an optical transport shelf, or a long-haul access platform, the module helps keep infrastructure choices focused on stable link delivery, service continuity, and compatibility with existing fiber-based network designs.

Key Advantages

Long-Reach Optical Performance
This sfp module is built for 622 Mb/s SDH STM-4 and SONET OC-12 links that need stable transmission over long distances, with support for up to 150 to 160 km on singlemode fiber. The 1550 nm DFB laser and APD receiver are selected to maintain signal quality over extended routes, which helps network teams reduce repeaters and keep long-haul network switch connections dependable in real operating conditions.

Industrial-Ready Integration
With hot-pluggable operation, LC duplex connectivity, single +3.3 V power supply, and DDM monitoring under SFF-8472, this module is practical for maintenance and fault tracking in managed optical systems. It is well-suited for ethernet switch and transport platforms used by industrial ethernet switch manufacturers, optical transceiver manufacturers, and top network switch manufacturers because it supports structured deployment, easier replacement, and stable performance across industrial, extended, and commercial temperature ranges.

Use Scenarios

Carrier and Telecom Backbone Links
In telecom rooms, carrier aggregation sites, and long-distance backbone installations, operators often need to carry SDH STM-4 or SONET OC-12 traffic across remote nodes without frequent signal loss. This transceiver works as the optical interface inside a transport network switch or transmission platform, and its 1550 nm long-reach design makes it a reliable choice where distance and signal stability are the main requirements.

Industrial Network Equipment Deployment
In factory networks, utility control rooms, and outdoor equipment cabinets, system integrators and panel builders need an SFP that can tolerate wider temperature conditions and support straightforward maintenance. This module fits those environments as a dependable optical link for an ethernet switch or poe switch, helping operators keep connected devices running while simplifying replacement and monitoring in industrial settings.
