• Single-mode intermediate-reach (IR) SFP module—SFP-OC48-IR1 OC48/STM16c
• Single-mode long-reach (LR) SFP module—SFP-OC48-LR2 OC48/STM16c
Each port on the 4-Port OC-48/STM-16 POS/RPR SPA has one duplex LC-type receptacle. For single-mode
optical fiber connections, you can use either a duplex LC-type cable or two simplex LC-type cables, one for
transmit (TX) and one for receive (RX).

Mate Interface Cables
The 4-Port OC-48/STM-16 POS/RPR SPA supports two mate interface configurations:
• Mate between two OC-192c SPAs in the same SIP
• Mate between two OC-192c SPAs in adjacent SIPs
Two SPAs are connected using a 40–pin connector copper mate cable. The length of the cables allow only
two possible connection scenarios, next slot horizontal and same slot vertical. This assumes that the chassis
is mounted vertically. The following figure shows the mate cables used to connect the SPAs.
