SONET/SDH OC48/STM16 SFP Optical Interface Specifications

M Series and T Series routers support the following SONET/SDH OC48/STM16 PICs with SFP. To determine which SFPs are supported, see the cables and connectors for each PIC.

  • Table 1 shows the optical interface specifications for SONET/SDH OC48/STM16 PICs with a short reach (SR-1) SFP.
  • Table 2 shows the optical interface specifications for SONET/SDH OC48/STM16 PICs with an intermediate reach (IR-1) SFP.
  • Table 3 shows the optical interface specifications for SONET/SDH OC48/STM16 PICs with a long reach (LR-1) SFP.
