OC-3 also known as STS-3 (electrical level) and STM-1 (SDH)， is a network line with transmission speeds of up to 155.52Mbit/s with optical fibers. OC-3 SFP modules are often used for Fast Ethernet, SDH/SONET and FTTx applications.

OC3 SFP (Small Form Factor Pluggable) module is specifically designed for the high performance integrated duplex data link over single mode optical fiber. These transceiver modules are compliant with the SFP Multisource Agreement (MSA). With the hot pluggability, these modules offer an easy way to be installed into SFP MSA compliant ports at any time without the interruption of the host equipments operating online.

Ingellen is a leading supplier of wide ranges of STM-1 SFP modules, all of our oc3 stm1 SFP transceivers can be manufactured to be complete compatible with major brands Cisco, Juniper, Hp, Dell, Alcatel ect., Ingellen can customize your required compatible OC3 SFP transceivers like Cisco OC3 SFP transceivers to fit for you special applications. Next I will introduce some major custom Cisco OC3 SFP transceivers that are available from us:

SFP-OC3-MM：
Description: OC-3/STM-1 pluggable short-reach (2 km) transceiver module, 1310-nm wavelength, MMF, LC connector
SFP-OC3-SR：
Description: OC-3/STM-1 pluggable short-reach (2 km) transceiver module, 1310-nm wavelength, LC connector
SFP-OC3-IR1：
Description: OC-3/STM-1 pluggable intermediate-reach (15 km) transceiver module, 1310-nm wavelength, LC connector
SFP-OC3-LR1：
Description: OC-3/STM-1 pluggable long-reach (40 km) transceiver module, 1310-nm wavelength, LC connector
SFP-OC3-LR2：

SFP-OC3-MM and SFP-OC3-SR are for Gigabit Ethernet and SONET/OC3 applications while SFP-OC3-IR1, SFP-OC3-LR1, SFP-OC3-LR2 are for SDH STM-1, I-1.1, SONET OC-3 SR1, Fast Ethernet, Other Optical Links applications.

OC-3 SFP Transceiver Platform Support and Minimum Software Release Requirements:
SPA-2XOC3-POS, SPA-4XOC3-POS, SPA-4XOC3-POS-V2, SPA-8XOC3-POS, SPA-1XOC3-ATM-V2, SPA-1XOC3-ATM-V2, SPA-3XOC3-ATM-V2, SPA-4XOC3-ATM
SPA software support is determined by the platform on which the SPA is installed. Refer to the SPA release notes for the correct software release.
