Extended range module engineered for metropolitan area network (MAN) rings.
As the physical and digital bridge between Europe and Asia, Istanbul demands unparalleled reliability and scale in its telecommunications infrastructure. The metropolitan network is currently experiencing a massive migration toward smarter, denser fiber layouts.
With initiatives like the Turkey National Broadband Strategy and the aggressive rollouts of fiber-to-the-home (FTTH) by major players like Turk Telekom, Turkcell Superonline, and Vodafone Turkey, high-quality optical modules are critical. At the center of this transformation are 1.25G and 2.5G SFP transceivers. These legacy and mid-tier modules act as the fundamental pillars for GPON residential access, metropolitan transport systems, enterprise networks in Levent, and industrial monitoring arrays in Hadımköy and Tuzla Organized Industrial Zones (OSB).
Istanbul's unique geographical challenge—spanning the Bosphorus Strait—places heavy emphasis on fiber efficiency. Wavelength Division Multiplexing (WDM) and high-power duplex LC modules, capable of transmitting over 40km or 80km, are vital in reducing optical fiber layout costs while ensuring high throughput across intercontinental routes.
For network architects, selecting the right form factor, wavelength, and distance classification is vital to budget efficiency and hardware durability. The table below outlines the core parameters required for modern network upgrades in Turkey.
| Module Type | Wavelength | Fiber Mode | Max Distance | Connector Type | Key Application Scenario |
|---|---|---|---|---|---|
| 1.25G SFP Copper | N/A (UTP) | Cat5e/Cat6 | 100m | RJ45 | Intra-rack switch connection & LAN networks |
| 1.25G SFP SX | 850nm | Multi-Mode (MMF) | 550m | LC Duplex | Enterprise server rooms and campus backbones |
| 1.25G SFP LX/LH | 1310nm / 1550nm | Single-Mode (SMF) | 10km - 40km | LC Duplex | Metropolitan ring nodes & ISP aggregation points |
| 2.5G SFP GPON OLT | 1490nm Tx / 1310nm Rx | Single-Mode (SMF) | 20km | SC Simplex | FTTH Last-Mile Distribution (GPON Network Edge) |
| 1.25G / 2.5G BiDi | Tx1310/Rx1550 (or vice versa) | Single-Mode (SMF) | 20km - 80km | LC Simplex | Fiber-constrained links across long-distance spans |
DOM/DDM Functionality: Every module produced by Kocent Optec Limited incorporates Digital Optical Monitoring (DOM) under the SFF-8472 standard. This feature permits Turkish telecom engineers to track parameters such as optical output power, receiver sensitivity, operating temperature, and laser bias current in real-time, preventing network downtime in crucial metropolitan links.

Supporting real-time smart traffic cameras and public security networks along major arteries (E-5 & TEM highways) using durable industrial temperature SFP modules.
As bandwidth requirements double, operators in Istanbul are evaluating future-proof transitions to ensure current network designs support seamless upgrades without requiring entirely new fiber paths.
In GPON infrastructures, legacy 2.5G down / 1.25G up configurations must coexist with XG-PON (10G/2.5G) and XGS-PON (10G/10G) wavelengths on the same physical fiber network. By using advanced coexistence elements (WDM filters), engineers can retain existing SFP client modules while provisioning ultra-high bandwidth packages for high-demand business towers in the Bosphorus region.
Kocent Optec Limited actively researches and implements these technological intersections, optimizing transceiver design with custom EEPROM programming to guarantee broad multi-vendor compatibility.
