Ingellen offers full line of SDH OC3 SFP fiber optic transceivers which support DDM/DOM, BIDI and CWDM/DWDM. SFP(Small Form-Factor Pluggable Interface Converter) optic modules, are small form factor pluggable module for multi-mode fiber Fast Ethernet, plug into a variety of SFP-based POS, TDM and ATM interfaces on router products. . Depending on the system OC-3 is also known as STS-3 (electrical level) and STM-1 (SDH). A STM-1 or OC-3 interface will reduce overall expenses and control costs by combining data and voice applications over one circuit. All of them can be provided with a very good price and reliable quality.912 Mbit/s, including path overhead) using fiber optics. Large economies of scale can be achieved by substituting multiple single T1/E1 trunks with a single fiber connection running at 155 Mbps, which OC-3/STM-1 does.608 Mbit/s; overhead: 6. OC-3 STM-1 is a network line with transmission speeds of up to 155.52 Mbit/s (payload: 148. This line of SFP optics supports the following three data rates at various reaches: OC-3/STM-1 SFP (155 Mbps), OC-12/STM-4 SFP (622 Mbps), and OC-48/STM-16 SFP (2,488 Gbps). More, you can easily find other SFP modules like OC-12 SFP and OC-48 SFP there. OC-3/STM-1 is a commonly used universal interface in the telecom community. Ingellen is a leading fiber optic manufacturer who has rich experience in fiber optical field. Depending on the market, the benefits can be seen as soon as you subscribe to more than 20 T1 or E1 circuits simultaneously. The products include: SFP-OC3-MM= OC-3/STM-1 pluggable short-reach (2 km) transceiver module, 1310-nm wavelength, MMF, LC connector SFP-OC3-SR= OC-3/STM-1 pluggable short-reach (2 km) transceiver module, 1310-nm wavelength, LC connector SFP-OC3-IR1= OC-3/STM-1 pluggable intermediate-reach (15 km) transceiver packaging machine for sale module, 1310-nm wavelength, LC connector SFP-OC3-LR1= OC-3/STM-1 pluggable long-reach (40 km) transceiver module, 1310-nm wavelength, LC connector SFP-OC3-LR2= OC-3/STM-1 pluggable long-reach (80 km) transceiver module, 1550-nm wavelength, LC connector The OC-3/STM-1 Module is a highly versatile access solution, suitable for various applications, including: DSLAM backhaul, POS router interconnect, Voice exchange interconnect, Interconnect of ATM switches, SDH/SONET network bridging and Distributed cross-connect. These modules are also used for Fast Ethernet application. The SFPs are compatible with the SONET/SDH and ATM standards, and support the digital diagnostic functions specified in the SFF-8742 Multi-Source Agreement (MSA) and the extended operating temperature range from 23 to185°F (-5 to 85°C). The OC-3/STM-1 SFP transceivers module is a high performance and cost effective fiber optic transceiver. Ingellen's original OC-3/STM-1 SFP transceivers are designed for Fast Ethernet & SDH STM-1&SONET OC-3, which can be used in fast ethernet switch, router and other networking equipments from Cisco and other brands like HP, Juniper and so on.
